Ultramodern treatments for malignant hepatocellular carcinoma (HCC) in clinics are ineffective and frequently produce impaired adherence from patients. Due to poor therapeutic efficiency and significant systemic side effects, we coupled chemo-photothermal targeted treatment for hepatocellular carcinoma (HCC) within a novel, versatile drug delivery system to overcome these issues. Targeted nanoparticle treatment also improves the efficacy of cancer therapy. Peptides are peculiarly well-suited as targeting moieties, with the powerful avidity. To achieve optimal targeting efficiency, potent peptide exhibit on nanostructures requires ideal development. In spite of its strong affinity for the tumor marker αVβ3 integrin receptor, the cyclo(Arg-Gly-Asp-D-Phe-Lys) (cRGD) peptide has gained widespread use. To achieve targeted chemo-photothermal treatment and near-infrared (NIR)/pH-responsive drug release, we construct a cRGD peptide-conjugated quercetin (QT) drug in the present investigation. This drug can be assembled into molybdenum selenide (MoSe₂) coated zinc oxide (MoSe₂/ZnO-PEG-QT-cRGD) nanocomposites (NCs). MoSe₂/ZnO-PEG-QT-cRGD NCs were synthesized and characterized using UV–Vis, FT-IR, XRD, FE-SEM, and DLS analyses. The nanocomposites exhibited quasi-spherical morphology with an average hydrodynamic diameter of ∼158 nm (PDI 0.22), showed high drug loading efficiency (77 %), and demonstrated pH- and NIR-sensitive QT release, with excellent photothermal conversion capacity. The MoSe₂/ZnO-PEG-QT-cRGD NCs that evolved were biocompatible, as shown by the MTT experiment. In vitro and in vivo findings indicated significantly enhanced therapeutic efficacy against Hep3B cells under NIR irradiation compared with non-targeted NCs. Therefore, this investigation may provide an innovative model for cancer detection and therapy, and findings may surely assist in enhancing the quality of life for cancer patients.

临床上对恶性肝细胞癌（HCC）的超现代治疗是无效的，并且经常导致患者的依从性受损。由于治疗效果不佳和显著的全身副作用，我们将化学-光热结合治疗肝细胞癌（HCC），在一个新的，多功能的药物输送系统中克服这些问题。靶向纳米颗粒治疗也提高了癌症治疗的疗效。多肽特别适合作为靶向部分，具有强大的贪婪性。为了达到最佳的靶向效果，强效肽在纳米结构上的展示需要理想的发展。尽管cyclo(arg - gly - asp - d - ph - lys) （cRGD）肽对肿瘤标志物α v - β3整合素受体具有很强的亲和力，但它已被广泛使用。为了实现靶向化学光热治疗和近红外(NIR)/ ph响应药物释放，本研究构建了一种cRGD肽偶联槲皮素（QT）药物。该药物可组装成硒化钼（MoSe2）包覆氧化锌（MoSe2/ZnO-PEG-QT-cRGD）纳米复合材料（NCs）。合成了MoSe2/ZnO-PEG-QT-cRGD NCs，并通过UV-Vis、FT-IR、XRD、FE-SEM和DLS分析对其进行了表征。该纳米复合材料具有准球形形态，平均水动力直径为~ 158 nm (PDI 0.22)，具有较高的载药效率（77%），并具有良好的光热转换能力，对pH和nir敏感的QT释放。MTT实验表明，进化的MoSe2/ZnO-PEG-QT-cRGD nc具有生物相容性。体外和体内实验结果表明，与非靶向NCs相比，NIR辐照对Hep3B细胞的治疗效果显著增强。因此，本研究可能为癌症的检测和治疗提供一种创新模式，研究结果必将有助于提高癌症患者的生活质量。

Cu-integrated metal-organic framework (MOF-199) has emerged as a significant semiconductor due to its remarkable stability and capacity for visible light absorption. Nevertheless, the catalytic efficiency of pure MOF-199 is significantly impeded by the rapid recombination of photogenerated charge carriers. To address this, the MOF-199 integrated with boron-doped graphene oxide (BGO) was synthesized using the in-situ growth method, resulting in the novel MOF-199/BGO composite for tetracycline (TC) degradation. The integration of MOF-199 and BGO efficiently modulates the band structure of the composite, thereby enhancing the separation of carriers. Additionally, a detailed analysis was conducted to assess the chemical, structural, morphological, and textural properties of the photocatalysts. Investigations on the electronic properties of the heterojunction demonstrated interfacial characteristics conducive to improved charge carrier separation and transport, as well as a potential Z-scheme charge transfer mechanism. The Z-scheme heterojunction concurrently optimizes the charge transfer path, resulting in a substantial improvement in charge carrier separation efficiency and a significant enhancement of the redox capability of the photocatalyst. The MOF-199/BGO heterojunction degraded 93 % of the TC under sunlight in 60 min with a kinetic rate constant of 0.026 min⁻¹, which is ∼1.5 times better than MOF-199 (0.0098 min⁻¹). Liquid chromatography-mass spectrometry (LC-MS) was used to identify degradation intermediates, while electron paramagnetic resonance (EPR) and radical trapping experiments confirmed the involvement of superoxide anions (^•O₂⁻) and hydroxyl radicals (^•OH). Reusability studies demonstrated remarkable stability, with the composite maintaining nearly 85 % efficiency across five consecutive cycles, highlighting its prospects for practical applications in wastewater treatment.

铜集成金属有机骨架（MOF-199）由于其卓越的稳定性和可见光吸收能力而成为一种重要的半导体材料。然而，纯MOF-199的催化效率明显受到光生载流子快速重组的阻碍。为了解决这一问题，采用原位生长方法合成了掺杂硼的氧化石墨烯（BGO）的MOF-199，得到了新型的降解四环素（TC）的MOF-199/BGO复合材料。MOF-199和BGO的集成有效地调节了复合材料的能带结构，从而增强了载流子的分离。此外，还详细分析了光催化剂的化学、结构、形态和结构特性。对异质结电子性质的研究表明，界面特性有利于改善载流子分离和输运，以及潜在的Z-scheme电荷转移机制。z型异质结同时优化了电荷转移路径，从而大大提高了电荷载流子分离效率，并显著增强了光催化剂的氧化还原能力。MOF-199/BGO异质结在60 min内降解了93%的TC，动力学速率常数为0.026 min−1，比MOF-199 （0.0098 min−1）好1.5倍。液相色谱-质谱（LC-MS）鉴定了降解中间体，电子顺磁共振（EPR）和自由基捕获实验证实了超氧阴离子（•O2−）和羟基自由基（•OH）的参与。可重复使用研究表明，该复合材料具有显著的稳定性，在连续五个循环中保持近85%的效率，突出了其在废水处理中的实际应用前景。

Biocompatible carbon quantum dots (CQDs) were prepared using a hydrothermal synthesis approach employing citric acid and urea as carbon and nitrogen sources, respectively. CQDs were characterized through the various analytical techniques, including HR-TEM, XRD, FTIR, UV–Vis, Raman spectroscopy, and fluorescence spectroscopy. The CQDs exhibited a uniform spherical morphology with an average particle diameter of 2.966 ± 0.89 nm and a quantum yield of 15 %. The CQDs exhibited selective sensing toward hexavalent chromium [Cr(VI)] through fluorescence quenching, with a linear detection range of 1–10 nM and detection limit of 0.09 nM, lower than most reported CQD-based Cr(VI) sensors. Time-resolved fluorescence studies showed quenching occurred through static and dynamic processes via surface complexation and electron/energy transfer. Other metal ions, including Cr(III), caused minimal interference, demonstrating oxidation-state-specific sensing. Real water sample analysis validated the sensor's practical applicability. Excitation–emission matrix analysis showed excitation-independent emission behavior, ensuring spectral stability. Zebrafish embryo studies proved CQDs' biocompatibility at low concentrations, enabling effective in vivo bioimaging, while Cr(VI) co-exposure caused concentration-dependent fluorescence reduction. The antibacterial activity of CQDs was evaluated using bacterial biofilm eradication experiments. CQDs effectively eradicated mature biofilms of S. aureus, P. aeruginosa, K. pneumoniae, and E. coli at 75 μg/mL, highlighting their significant antibacterial properties. These findings suggest that the synthesized CQDs are ideal for Cr(VI) detection in aquatic ecosystems and living cells and have potential for bioimaging and antibacterial applications.

以柠檬酸和尿素为碳源和氮源，采用水热法制备了生物相容性碳量子点（CQDs）。通过各种分析技术，包括HR-TEM， XRD， FTIR, UV-Vis，拉曼光谱和荧光光谱对CQDs进行了表征。CQDs具有均匀的球形结构，平均粒径为2.966±0.89 nm，量子产率为15%。cqd通过荧光猝灭对六价铬[Cr(VI)]表现出选择性传感，线性检测范围为1 ~ 10 nM，检出限为0.09 nM，低于大多数cqd基Cr（VI）传感器。时间分辨荧光研究表明，猝灭是通过表面络合和电子/能量转移的静态和动态过程发生的。其他金属离子，包括铬（III），造成最小的干扰，显示氧化状态特异性传感。实际水样分析验证了传感器的实用性。激发-发射矩阵分析显示出与激发无关的发射行为，保证了光谱的稳定性。斑马鱼胚胎研究证明了CQDs在低浓度下的生物相容性，可以有效地进行体内生物成像，而Cr（VI）共暴露导致浓度依赖性荧光降低。通过细菌生物膜根除实验对CQDs的抑菌活性进行了评价。在75 μg/mL浓度下，CQDs能有效根除金黄色葡萄球菌、铜绿假单胞菌、肺炎克雷伯菌和大肠杆菌的成熟生物膜，显示出显著的抗菌性能。这些结果表明，合成的CQDs是水生生态系统和活细胞中Cr（VI）检测的理想选择，具有生物成像和抗菌应用潜力。

This paper proposes a strategy of oxalic acid-regulated cobalt ion doping to construct a multi-phase coexisting vanadium-based cathode material (CoVO) through a one-step hydrothermal method, and systematically studies its influence on the electrochemical performance of aqueous zinc-ion batteries. The study systematically investigates the effects of oxalic acid concentration on the phase composition, valence state distribution of vanadium, and oxygen defect concentration of CoVO, revealing the enhancement mechanism of electrochemical performance by the synergistic effect of multiphase, oxygen deficiency and Co ions. The experimental results show that the optimized CoVO-3 sample achieves a high specific capacity of 317 mAh g⁻¹ at a current density of 0.1 A g⁻¹ and maintains a capacity retention rate of 89.71 % after 2000 cycles at 5 A g⁻¹. The rational design in multi-phase interface, enhancement of electronic conductivity due to Co²⁺ doping and pseudocapacitive energy storage dominating mechanism are responsible for the superior activity of CoVO-3 sample. Besides, the kinetic results prove that multi-phase interface and oxygen defects will enhance rapidly insertion/extraction kinetics of Zn²⁺ from the synergistic effect. In this paper, we present an alternative design strategy to create high-performance and long-cycle-stable cathode materials for aqueous zinc ion batteries.

本文提出了草酸调控钴离子掺杂的策略，通过一步水热法制备多相共存钒基正极材料（CoVO），并系统研究了其对水性锌离子电池电化学性能的影响。本研究系统考察了草酸浓度对CoVO中钒的物相组成、价态分布和氧缺陷浓度的影响，揭示了多相、缺氧和Co离子协同作用增强CoVO电化学性能的机理。实验结果表明，优化后的CoVO-3样品在0.1 a g−1电流密度下可获得317 mAh g−1的高比容量，在5 a g−1电流密度下循环2000次后容量保持率为89.71%。多相界面的合理设计、Co2+掺杂导致的电子电导率的增强以及赝电容储能主导机制是CoVO-3样品具有优异活性的原因。此外，动力学结果表明，多相界面和氧缺陷会从协同效应上增强Zn2+的快速插入/萃取动力学。在本文中，我们提出了一种替代设计策略，以创建高性能和长周期稳定的锌离子电池正极材料。

Developing heterojunctions has been widely recognized as an effective strategy for enhancing catalytic performance. In this context, nature-inspired approaches for nanomaterial synthesis have emerged as a potent way to further elevate the functional and catalytic properties of these materials. This study explores the advanced usage of Datura innoxia Mill flowers in the synthesis of Pure Bi₂O₃ (BO), Fe₂O₃ (FO) nanoparticles (NPs), and Bi₂O₃/BiFeO₃ nanocomposites (NCs), highlighting its dual role as a bio-reductant and stabilizing agent. NPs and NCs were characterized using several analytical examinations. Pure BO NPs and FO NPs exhibit band gaps of 3.47 ± 0.05 eV and 2.2 ± 0.1 eV, respectively. The Bi₂O₃/BiFeO₃ (BBFO) NCs exhibit a band gap of 2.1 ± 0.05 eV, which is attributed to the formation of an in-situ Type-II heterojunction between BO and BiFeO₃ (BFO). The photocatalytic activity of BBFO NCs demonstrated varying efficiencies for the degradation of three industrial dyes, such as Methylene Blue (MB), Rhodamine B (Rh-B), and Rose Bengal (RB), under visible light irradiation. The degradation efficiencies were 26% for MB, 75% for Rh-B, and 80% for RB. Notably, BBFO NCs achieved an excellent degradation efficiency of 96.5% for RB using 30 mg of the catalyst within a period of 150 min. Datura significantly increased the photocatalytic activity for RB degradation by stabilizing the catalyst through its capping ability. Photoluminescence (PL) investigations were used to examine the nanomaterials' (NMs') optical light emission characteristics. With all of the NMs emitting blue light, a lower PL intensity signified higher catalytic activity of the NCs. The developed BO, FO NPs, and BBFO NCs were examined for the development of low-cost Latent Fingerprints (LFPs) detection. The NCs demonstrated high-quality LFP visualization, highlighting their potential in forensic applications. Consequently, BBFO emerges as an efficient material for photochemical, catalytic, and forensic technologies, and is anticipated to play a significant role in future advanced applications.

发展异质结被广泛认为是提高催化性能的有效策略。在这种背景下，受自然启发的纳米材料合成方法已经成为进一步提高这些材料的功能和催化性能的有效方法。本研究探讨了曼陀罗花在合成纯Bi2O3 （BO）、Fe2O3 （FO）纳米粒子（NPs）和Bi2O3/BiFeO3纳米复合材料（nc）中的先进应用，突出了其作为生物还原剂和稳定剂的双重作用。NPs和NCs通过几种分析检查进行了表征。纯BO NPs和FO NPs的带隙分别为3.47±0.05 eV和2.2±0.1 eV。Bi2O3/BiFeO3 (BBFO) NCs的带隙为2.1±0.05 eV，这是由于BO和BiFeO3 （BFO）之间形成了ii型异质结。BBFO纳米纤维素在可见光下降解亚甲基蓝（MB）、罗丹明B （Rh-B）和孟加拉玫瑰（RB）等三种工业染料的光催化活性表现出不同的效率。MB的降解效率为26%，Rh-B为75%，RB为80%。值得注意的是，BBFO NCs在使用30 mg催化剂的情况下，在150 min的时间内对RB的降解效率达到了96.5%。曼陀罗通过其旋盖能力稳定催化剂，显著提高了RB降解的光催化活性。采用光致发光（PL）研究了纳米材料的光学发光特性。所有的NMs都发出蓝光，较低的PL强度表明NCs的催化活性较高。研究了发达的BO、FO NPs和BBFO NPs，以开发低成本的潜在指纹（LFPs）检测方法。NCs展示了高质量的LFP可视化，突出了它们在法医应用中的潜力。因此，BBFO作为光化学、催化和法医技术的高效材料出现，并有望在未来的高级应用中发挥重要作用。

The degradation efficiencies were 26% for MB, 75% for Rh-B, and 80% for RB. Notably, BBFO NCs achieved an excellent degradation efficiency of 96.5% for RB using 30 mg of the catalyst within a period of 150 min. Datura significantly increased the photocatalytic activity for RB degradation by stabilizing the catalyst through its capping ability. Photoluminescence (PL) investigations were used to examine the nanomaterials' (NMs') optical light emission characteristics. With all of the NMs emitting blue light, a lower PL intensity signified higher catalytic activity of the NCs. The developed BO, FO NPs, and BBFO NCs were examined for the development of low-cost Latent Fingerprints (LFPs) detection. The NCs demonstrated high-quality LFP visualization, highlighting their potential in forensic applications. Consequently, BBFO emerges as an efficient material for photochemical, catalytic, and forensic technologies, and is anticipated to play a significant role in future advanced applications.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"185 ","pages":"Article 116038"},"PeriodicalIF":5.4,"publicationDate":"2025-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145881699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inflammatory processes and responses can contribute to development and progression of several diseases including atherosclerosis, gastrointestinal disorders, diabetes, rheumatoid arthritis, asthma, and cancer. Nanotechnology can display several beneficial effects in medicine which can aid in diminishing the adverse effects displayed by conventional anti-inflammatory drugs. In the current study, we synthesized zinc oxide nanoparticles using Jasminum azoricum leaf extract (JA-ZnO NPs) and characterized them using Ultraviolet-Visible (UV–Vis) spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), X-Ray diffraction (XRD) analysis, Dynamic Light Scattering (DLS), Hi-Resolution Transmission electron microscopy (HR-TEM), Field Emission Scanning electron microscopy (FE-SEM) and energy dispersive X-ray analysis (EDAX) analyses. The in vitro anti-inflammatory effects were determined using cyclooxygenase (COX) and lipoxygenase (LOX) inhibition assays. The in vivo anti-inflammatory effects were determined in male Wistar rats by determining the paw edema inhibition and the inflammation of the paw tissue was determined using haematoxylin and eosin (H&E) staining. Immunohistochemical (IHC) analysis was performed using antibodies for IL-6 and COX-2. The results indicated that JA-ZnO NPs possessed significant anti-inflammatory effects both in vitro and in vivo. This study paves way for further analysis of nanomaterials for use as anti-inflammatory agents in clinic.

炎症过程和反应可促进几种疾病的发生和进展，包括动脉粥样硬化、胃肠道疾病、糖尿病、类风湿关节炎、哮喘和癌症。纳米技术可以在医学上显示出一些有益的作用，可以帮助减少传统消炎药所显示的副作用。本研究以azoricum叶片提取物（JA-ZnO NPs）为原料合成氧化锌纳米颗粒，并利用紫外可见光谱（UV-Vis）、傅里叶红外光谱（FTIR）、x射线衍射（XRD）、动态光散射（DLS）、高分辨率透射电子显微镜（HR-TEM）、场发射扫描电子显微镜（FE-SEM）和能量色散x射线分析（EDAX）对其进行了表征。采用环氧合酶（COX）和脂氧合酶（LOX）抑制法测定其体外抗炎作用。通过测定雄性Wistar大鼠足部水肿抑制程度来测定其体内抗炎作用，并用血红素和伊红（H&；E）染色法测定其足部组织炎症程度。使用IL-6和COX-2抗体进行免疫组化（IHC）分析。结果表明，JA-ZnO NPs在体内外均具有明显的抗炎作用。本研究为进一步分析纳米材料在临床中的抗炎作用铺平了道路。

The discharge of uranium-containing wastewater from nuclear fuel production poses severe threats to human health and environmental security due to the high mobility, solubility, and radiotoxicity of hexavalent uranium (U(VI)). However, developing an adsorbent that simultaneously achieves high adsorption capacity, fast kinetics, strong selectivity and good recyclability remains a major challenge. In this paper, porous boron nitride-loaded ZIF-67 composites (BN@ZIF-67-X) were synthesized by a simple in situ growth method and used for the removal of U(VI) from aqueous solutions. The results showed that BN@ZIF-67 exhibited excellent adsorption properties for U(VI) than pure p-BN and ZIF-67. It also demonstrated acceptable cyclic regeneration properties. In addition, the adsorption of U(VI) by BN@ZIF-67-2 achieved equilibrium within 60 min, the adsorption kinetics were well-described by the pseudo-second-order model, the isothermal model conformed to the Langmuir isothermal model, and the adsorption was an endothermic monolayer chemisorption process. The maximum adsorption capacity of U(VI) by BN@ZIF-67-2 was calculated to be 550.306 mg g⁻¹. Moreover, the adsorption of BN@ZIF-67-2 exhibited excellent selectivity in the adsorption of U(VI), which was dominated by surface complexation. In conclusion, BN@ZIF-67 is a promising adsorbent for the adsorption of U(VI) from aqueous solution.

由于六价铀（U(VI)）的高流动性、溶解度和放射性毒性，核燃料生产中含铀废水的排放对人类健康和环境安全构成严重威胁。然而，开发一种同时具有高吸附量、快速动力学、强选择性和良好可回收性的吸附剂仍然是一个重大挑战。本文采用简单的原位生长方法合成了多孔氮化硼负载的ZIF-67复合材料（BN@ZIF-67-X），并将其用于去除水溶液中的U（VI）。结果表明，BN@ZIF-67对U（VI）的吸附性能优于纯p-BN和ZIF-67。它还表现出可接受的循环再生性能。此外，BN@ZIF-67-2对U（VI）的吸附在60 min内达到平衡，吸附动力学符合拟二阶模型，等温模型符合Langmuir等温模型，吸附过程为吸热单层化学吸附过程。BN@ZIF-67-2对U（VI）的最大吸附量为550.306 mg g−1。此外，BN@ZIF-67-2对U（VI）的吸附表现出优异的选择性，以表面络合为主。综上所述，BN@ZIF-67是一种很有前途的吸附U（VI）的吸附剂。

The many benefits of materials that absorb electromagnetic waves—such as lowering electromagnetic interference, enhancing communication, and encouraging environmental sustainability—have drawn a lot of attention and will help ensure sustainable growth in the future. In this study, manganese‑nickel layered double hydroxide (MnNi-LDH) with a flower-like structure was successfully synthesized using a simple hydrothermal method. To overcome the limitation of a single loss mechanism in MnNi-LDH, Ti₃C₂T_x MXene, featuring an accordion-like layered structure, was introduced. The combination of the two-dimensional Ti₃C₂T_x MXene and flower-like MnNi-LDH significantly enhances the electromagnetic wave absorption properties. The LDH/MXene composite exhibits an effective absorption bandwidth from 6.9 GHz to 9.1 GHz with a thickness of only 2.045 mm and a minimum reflection loss (RL_min) of −50.3 dB at 7.8 GHz when the Ti₃C₂T_x MXene mass fraction reaches 30%. These findings indicate that the LDH/MXene composite may be a suitable electromagnetic wave absorber.

Doxorubicin (DOX) remains one of the most effective chemotherapeutic agents; however, its clinical application is restricted by dose-dependent cardiotoxicity and off-target systemic effects. To address these limitations, we engineered a ROS-responsive nanocarrier system composed of Iron oxide @OA-Starch-DOX-NPs. Magnetic iron oxide nanoparticles (Iron oxide NPs) were synthesized through a green route using Citrus sinensis peel extract, subsequently functionalized with oleic acid (OA) and starch, and finally loaded with DOX. The presence of a double bond in OA enables lipid peroxidation under elevated ROS conditions, leading to oxidative disruption of the OA coating and triggering accelerated drug release within ROS-rich tumor microenvironments. The resulting nanostructures exhibited uniform spherical morphology (15–20 nm), high drug encapsulation efficiency (87.25 ± 1.12 %), and pH/ROS-responsive release behavior, with enhanced DOX liberation under acidic conditions attributable to starch degradation. Comprehensive physicochemical characterization confirmed their magnetic responsiveness (55.40 emu/g), thermal stability, and expected elemental composition. In vitro assays demonstrated significant anticancer activity against MCF-7 breast cancer cells (IC₅₀ = 30.2 μg/mL) and notable anti-inflammatory potential (IC₅₀ = 25.08 μg/mL). Collectively, these findings highlight Iron oxide@OA-Starch-DOX-NPs as a robust and promising platform for targeted and stimuli-responsive cancer therapy.

阿霉素（DOX）仍然是最有效的化疗药物之一；然而，其临床应用受到剂量依赖性心脏毒性和脱靶全身效应的限制。为了解决这些限制，我们设计了一种由氧化铁@ oa -淀粉- dox - nps组成的ros响应纳米载体系统。以柑桔果皮提取物为原料，通过绿色通道合成磁性氧化铁纳米颗粒（iron oxide NPs），然后用油酸（OA）和淀粉进行功能化，最后负载DOX。OA中双键的存在使脂质在ROS升高的条件下发生过氧化，导致OA涂层的氧化破坏，并在富含ROS的肿瘤微环境中触发加速药物释放。所制备的纳米结构具有均匀的球形形貌（15-20 nm）、高包封效率（87.25±1.12%）和pH/ ros响应释放行为，并且由于淀粉降解，在酸性条件下DOX释放增强。综合物理化学表征证实了它们的磁响应性（55.40 emu/g）、热稳定性和预期的元素组成。体外抗MCF-7乳腺癌细胞抑癌活性（IC50 = 30.2 μg/mL），抗炎活性（IC50 = 25.08 μg/mL）。总的来说，这些发现突出了铁oxide@OA-Starch-DOX-NPs作为靶向和刺激反应性癌症治疗的一个强大而有前途的平台。
