Recent findings have sparked great interest in MagR/Cry4 protein that underpin animal magnetoreception. We tried to make progress in characterizing the Columba livia clMagR/clCry4, and connecting its properties to biological impacts. Throughout natural evolution, new functions of protein were never constructed from scratch, but from pre-existing parts. The clMagR/clCry4 was certainly not an exception. By employing synthetic biology, protein heterologous expression approach allowed protein function to be borrowed from nature to study their new traits. We introduced clMagR/clCry4 into the natural bacteria constructing the recombinant bacteria that perform biomineralization process. Our current work efforts were focused on investigating iron biomineralization in clMagR/clCry4 using electron microscopy. This is only one study, thus far, that describes clMagR/clCry4 deem as a likely candidate as iron biomineralization protein. Notably, iron biomineralization brings clMagR/clCry4 closer to its potential magnetoreception. Additionally, the obtained iron biominerals have shown a great promise to serve as T₂ contrast agents for MRI application.

最近的发现引起了人们对支撑动物磁接受的MagR/Cry4蛋白的极大兴趣。我们试图在Columba livia clMagR/clCry4的表征以及将其特性与生物学影响联系起来方面取得进展。在整个自然进化过程中，蛋白质的新功能从来都不是从零开始构建的，而是从已有的部分中构建的。clMagR/clCry4当然也不例外。利用合成生物学的方法，利用蛋白质的异源表达，从自然界借用蛋白质的功能，研究蛋白质的新特性。我们将clMagR/clCry4引入到天然细菌中，构建了进行生物矿化过程的重组细菌。我们目前的工作重点是利用电子显微镜研究clMagR/clCry4中的铁生物矿化。到目前为止，这只是一项研究，描述了clMagR/clCry4被认为是铁生物矿化蛋白的可能候选者。值得注意的是，铁生物矿化使clMagR/clCry4更接近其潜在的磁受体。此外，获得的铁生物矿物已经显示出作为MRI应用的T2造影剂的巨大前景。

Optical materials with imaging and phototherapy functionalities have offered promising perspectives for precise tumor treatment. Among these materials, boron-dipyrromethene (BODIPY) photosensitizers have presented potential for cancer theranostics because of their long wavelength absorption/fluorescence, tunable reactive oxygen species quantum yield, excellent photostability, and good biocompatibility. The development of nanotechnology in combination with BODIPY provided researchers with nanomedicines passively targeting solid tumors via enhanced penetration and retention effect, which greatly improved the efficacy of cancer photo-theranostics. In this review, we summarize our contributions for the development of BODIPY nanomedicine for cancer imaging and phototherapy. We firstly introduce our comprehensive routes for BODIPY synthesis and the preparation strategies of BODIPY nanomedicine. Thereafter, we give an in-depth discussion on the photo physicochemical properties of BODIPY nanomedicines, focusing on their applications in fluorescence/photothermal/photoacoustic imaging, photodynamic therapy, phototherapy, and combined phototherapy/vascular disruption therapy. Lastly, we look at the perspectives and challenges for the development of next-generation BODIPY nanomedicines.

We investigated how structures formed by hydrophobic superparamagnetic Fe₃O₄ nanoparticles (NPs) at air-water interfaces could be changed, in order to achieve films with the desired structure. NP films were prepared on water using the Langmuir trough, and deposited onto glass substrates. The effect of the NP spreading solution concentration (C_NP) and the magnetic field strength on the NP aggregation were determined from surface pressure-area/particle isotherms and Atomic Force Microscope images. In the absence of a magnetic field, the NPs aggregated to form large and heterogeneous domains. The size and non-homogeneity of the domains increased as C_NP increased, a result explained by increasing attractive hydrophobic interactions. A magnetic field decreased the size and non-homogeneity of these domains, a result explained by a directional attractive magnetic force. The NP film structure depended on C_NP and the magnetic field strength. Structural changes by the magnetic field became more visible as C_NP was increased.

我们研究了如何改变由疏水超顺磁性Fe3O4纳米颗粒（NPs）在空气-水界面形成的结构，以获得具有所需结构的薄膜。利用Langmuir槽在水中制备NP膜，并将其沉积在玻璃基板上。通过表面压力-面积/粒子等温线和原子力显微镜图像，研究了NP扩散溶液浓度（CNP）和磁场强度对NP聚集的影响。在没有磁场的情况下，NPs聚集形成大而不均匀的畴。随着CNP的增加，结构域的大小和非均匀性增加，这一结果可以通过增加吸引疏水相互作用来解释。磁场减小了这些畴的尺寸和非均匀性，这一结果可以用方向性磁力来解释。NP膜的结构取决于CNP和磁场强度。随着CNP的增加，磁场引起的结构变化更加明显。

The past few decades have witnessed plenty of research activities in advanced adsorbents for iodine pollutant treatment, but little attention has been paid to the reutilization of them. Herein, we report on superficial pyrrolidone-rich polymer nanoparticles (i.e., PMP NPs) as integrated sustainable materials for the effective removal of iodine from waste, coupled with their reutilization in antibacterial-associated areas. The pyrrolidone groups on the surface of PMP NPs served as adsorbing sites for capturing iodine and having the special capability of desorbing iodine in the presence of starch or bacteria. The as-captured iodine showed excellent in vitro antibacterial ability against 10⁷ CFU·mL⁻¹ of Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). We believed that this “turning waste into treasure” strategy based on the synergism of iodine adsorption and antibacterial utilization should have great potential for environmental remediation and public healthcare.

近几十年来，国内外对高级吸附剂处理碘污染物的研究较多，但对其资源化利用的关注较少。在此，我们报道了富含表面吡咯烷酮的聚合物纳米颗粒（即PMP NPs）作为有效去除废物中碘的综合可持续材料，以及它们在抗菌相关领域的再利用。PMP NPs表面的吡咯烷酮基团是吸附碘的位置，在淀粉或细菌存在的情况下具有解吸碘的特殊能力。捕获的碘对大肠杆菌（E. coli）和金黄色葡萄球菌（S. aureus）的体外抑菌能力为107 CFU·mL−1。我们认为，这种基于碘吸附和抗菌利用协同作用的“变废为宝”策略在环境修复和公共医疗保健方面具有很大的潜力。

The control of structure is crucial for diverse applications of colloidal crystals. Open-structure colloidal crystals are promising in their novel optical or mechanical properties, yet fabrication remains a significant challenge. Here, we demonstrate fabrication of multi-layer colloidal kagome lattices via heteroepitaxial growth. Unlike previous methods that rely on anisotropic particles, such as Janus particles, our approach utilizes common isotropic spherical polystyrene particles. We fabricated multi-layered kagome lattices, in contrast to techniques that were limited to forming single layers. The first layer in the kagome lattice formation on a substrate was a multi-step process, as revealed by in situ-observations. Then repeated stacking of kagome lattice layers occurred stably. This heteroepitaxial growth technique offers a feasible approach to self-assemble open-structure colloidal crystals.

胶体晶体的结构控制是胶体晶体多种应用的关键。开放结构胶体晶体在其新的光学或机械性能方面很有前途，但制造仍然是一个重大挑战。在这里，我们展示了通过异质外延生长制备多层胶态kagome晶格。与之前依赖于各向异性粒子（如Janus粒子）的方法不同，我们的方法利用了普通的各向同性球形聚苯乙烯粒子。我们制造了多层的kagome晶格，而不是局限于形成单层的技术。原位观察表明，在衬底上形成kagome晶格的第一层是一个多步骤的过程。然后稳定地重复堆叠kagome晶格层。这种异质外延生长技术为自组装开放结构胶体晶体提供了一种可行的方法。

Piezocatalysis has attracted much attention for its efficient performance in removing pharmaceuticals and dyes from wastewater. In this work, the piezoelectric system was applied by environmental-benign BiFeO₃ catalysis for the removal of antibiotics in the water. The irregular honeycomb-like BiFeO₃ was prepared through a simple co-precipitation route with composite precipitants. The results demonstrated that BiFeO₃ exhibited excellent piezoelectric catalytic degradation performance for metronidazole under ultrasonic vibration. The effects of catalyst dosage, initial metronidazole concentration, solution pH, and ultrasonic power on piezoelectric catalytic efficiency were systematically investigated. It was found that the highest piezoelectric catalytic degradation efficiency of metronidazole was 98.87 %. The catalyst stability of the catalyst showed that it had excellent piezoelectric catalytic degradation Finally, the degradation efficiency of metronidazole was only reduced by 4 % through four cycles, which demonstrated the good stability and reusability of BiFeO₃.

Bioadhesives are widely used in medical fields due to their compatibility with biological soft tissues and their ability to facilitate non-invasive wound closure. Despite their widespread clinical applications, the inadequate adhesion performance highlights the need for further refinement and innovation of these materials. A profound comprehension of the underlying mechanisms of tissue adhesion is essential for the successful development of bioadhesives. This review elucidates adhesion mechanisms and design principles for bioadhesives, emphasizing strategies to enhance interfacial adhesion and cohesion performance. We also provide a forward-looking perspective on the challenges and emerging trends for the development of next-generation bioadhesives. The progress of bioadhesives has significant potential to revolutionize wound management.

The present study aims to explore the potential role of curcumin and piperine loaded spongosomes to protect the skin against pollution-induced damage. The hydration of a glyceryl monooleate and sodium cholate thin film, followed by homogenization, led to dispersions with an internal spongiform structure, as demonstrated by cryogenic transmission electron microscopy and small angle X-ray scattering. Spongosome mean diameter measured by photon correlation spectroscopy was roughly 200 nm. Curcumin and piperine were efficiently encapsulated in spongosomes, as demonstrated by ultrafiltration and HPLC analysis. In vitro permeation tests revealed that piperine enhances the penetration of curcumin, suggesting a further improved bioavailability and sustained release. Ex vivo studies using human skin biopsies showed that curcumin and piperine-loaded spongosomes protect the skin against diesel exhaust emissions, preserving the levels of key skin barrier proteins, as filaggrin and involucrin. The formulations exhibited non-irritating properties in human patch tests, supporting their suitability for topical application.

本研究旨在探讨姜黄素和胡椒碱负载的海绵体在保护皮肤免受污染损伤中的潜在作用。单油酸甘油酯和胆酸钠薄膜的水合作用，随后均质化，导致具有内部海绵状结构的分散体，如低温透射电子显微镜和小角度x射线散射所示。光子相关光谱测得海绵体平均直径约为200 nm。超滤和高效液相色谱分析表明，姜黄素和胡椒碱被有效地包裹在海绵体中。体外渗透试验表明，胡椒碱增强了姜黄素的渗透，进一步提高了姜黄素的生物利用度和缓释。利用人体皮肤活检进行的离体研究表明，姜黄素和装载胡椒碱的海绵体可以保护皮肤免受柴油废气排放的影响，保持关键皮肤屏障蛋白的水平，如聚丝蛋白和天花苷。该配方在人体贴片试验中表现出无刺激性，支持其局部应用的适用性。
