Background: Green synthesis of nanoparticles has been emerging as interesting and expanding research area due to environmentally friendly, non-toxic, clean, less costly route and also it can be done at room pressure and temperature. Blumea lacera is described as a valuable medicinal plant in many vital systems of medicines. The study explored the eco-friendly green synthesis of MnO2 NPs using Blumea lacera leaf extract.Method: Reduction of potassium permanganate (KMnO4) using Blumea lacera leaf extract were carried out at room temperature. The crude extract of Blumea lacera were added to metal ion reagents of specific volume and specific concentration at ambient temperature and stirred continuously using magnetic stirrer. The aqueous leaf extract reduced and stabilized the KMnO4 into MnO2 NPs. The MnO2 NPs obtained from the solution was purified and separated by repeated centrifugation using Remi cooling centrifuge model C-24.Results: The biosynthesized MnO2 NPs characterized by UV–Vis spectroscopy showed an absorption peak at 400 nm. The XRD studies revealed the spherical shape of MnO2 NPs with an average particle diameter of 20 nm. FT-IR analysis confirmed the presence of functional groups -OH, C=O, C=C, and C-H triggering the synthesis of MnO2 NPs. Vibrational mode at around 606.62 and 438.81 cm−1 supports the occurrence of O–Mn–O bond. Conclusion: The synthesized MnO2 NPs was found to be a good antibacterial and antifungal agent against bacterial stain Staphylococcus aureus, S. bacillus, Pseudomonas aeruginosa, E. coli and fungal stain C. albicans, Aspergillus niger and Sclerotium rolfsii.
背景:纳米颗粒的绿色合成具有环境友好、无毒、清洁、成本低、可在室温和常压条件下进行等优点,已成为研究的热点。蓝草在许多重要的药物系统中被描述为一种有价值的药用植物。本研究探索了以蓝草叶提取物为原料,绿色环保地合成二氧化锰NPs的方法。方法:采用蓝草叶提取物在室温下还原高锰酸钾(KMnO4)。将蓝草粗提物在常温下加入比体积、比浓度的金属离子试剂中,用磁力搅拌器连续搅拌。叶提取物将KMnO4还原稳定为MnO2 NPs。利用C-24型Remi冷却离心机对溶液中得到的MnO2 NPs进行反复离心纯化和分离。结果:生物合成的二氧化锰纳米粒子在400 nm处有一个吸收峰。XRD分析表明,MnO2纳米颗粒呈球形,平均粒径为20 nm。FT-IR分析证实了-OH、C=O、C=C和C- h等官能团的存在,触发了MnO2 NPs的合成。在606.62和438.81 cm−1附近的振动模式支持O-Mn-O键的形成。结论:合成的MnO2 NPs对金黄色葡萄球菌、芽孢杆菌、铜绿假单胞菌、大肠杆菌和白色念珠菌、黑曲霉、罗氏菌核具有良好的抗菌和抗真菌作用。

This study aimed to design and statistically optimize the potential of intranasaly delivered chitosan wrapped linagliptin nanosuspension as an alternative approach for brain targeting for enhancing cognitive behaviour, increasing its solubility/permeability characteristics and reducing the side effects.Linagliptin nanosuspensions were prepared by nanoprecipitation method. We investigated the effects of independent variables, i.e., linagliptin concentration (D), Chitosan concentration (P) on the dependent factors like % drug loading (R1), % entrapment efficiency (R2) and % drug release (R3) via a central composite design. Furthermore, the optimized formulation was evaluated for surface morphology/size, ex-vivo permeation study, in-vitro release study, and stability study.The optimized formulation was further evaluated by different evaluation parameters such FESEM & TEM study of the optimized formulation (LS 1) showed spherical morphology. Mean particle size (250.7 nm), charge (-16.3 mV), % entrapment efficiency (95.8 ± 1.45 %), % drug loading (35.78 ± 0.19 %) was achieved. Saturation solubility (0.987 mg/ml), in vitro dissolution rate (89.65 ± 0.82 %) and ex vivo permeation (82.23 ± 1.25 %) of LS 1 were higher than pure Linagliptin.Response surface methodology was applied successfully to obtain LS 1 as an optimized formulation with enhanced solubility and dissolution characteristics at minimized dose alleviating side effects and with improvised cognitive effects. Thus, an efficient intranasal delivery platform of linagliptin based on nanosuspension was designed for bypassing the BBB and delivering therapeutics directly to the brain. This can be a futuristic approach for enhancing cognitive effects by linagliptin nanosuspension via intranasal route.
本研究旨在设计和统计优化经鼻给药壳聚糖包裹利格列汀纳米混悬液的潜力,作为脑靶向治疗的替代方法,以增强认知行为,增加其溶解度/渗透性特征并减少副作用。采用纳米沉淀法制备利格列汀纳米混悬液。通过中心复合设计考察了利格列汀浓度(D)、壳聚糖浓度(P)对药物负荷% (R1)、包封率% (R2)和药物释放% (R3)等因变量的影响。并对优化后的制剂进行了表面形貌/尺寸、体外渗透、体外释放和稳定性研究。通过FESEM和TEM等不同评价参数对优化后的配方进行了进一步的评价,优化后的配方(LS 1)形貌呈球形。平均粒径(250.7 nm),电荷(-16.3 mV),包封效率(95.8±1.45%),载药量(35.78±0.19%)。LS - 1的饱和溶解度(0.987 mg/ml)、体外溶出度(89.65±0.82%)和体外透入度(82.23±1.25%)均高于利格列汀纯品。响应面法成功地获得了LS 1的最佳配方,该配方在最小剂量下具有增强的溶解度和溶出特性,减轻了副作用,并具有临时的认知效果。因此,设计了一种基于纳米混悬液的利格列汀有效的鼻内给药平台,可以绕过血脑屏障,直接将治疗药物输送到大脑。这可能是一种未来的方法,通过鼻内途径增强利格列汀纳米混悬液的认知效果。

Polymer-based nanofibril finds its application in various fields including tissue engineering, environmental monitoring, food packaging, and micro/nanoelectromechanical systems. These nanofibrils are subjected to chemical treatment and constant stress, which may cause permanent deformation to the fibrils when it is used. Therefore, the synthesis of well-defined nanofibrils and characterization techniques are key elements in identifying desired chemical and physical properties for suitable applications. Many methods have been developed to prepare individual nanofibrils, including electrospinning, phase separation, template synthesis, and self-assembly. Among all, self-assembly offers simple, efficient, and low-cost strategies that produce high-ordered nanofibirls using noncovalent interactions including hydrogen bonding, electrostatic interactions, π-π interactions, and hydrophobic interactions. The first part of the review provides detailed molecular interactions and simulations that can be controlled to achieve the formation of well-defined individual nanofibrils. The second part of the review describes the various existing tools to characterize the chemical and physical properties of single nanofibrils including atomic force microscopy. In the final part of the review, recently developed novel nanotools that measure the mechanical properties of nanofibrils are described. By bridging the gap between molecular interactions and resulting nanoscale fibirls, physical and chemical properties may lead to the construction of novel nanomaterials in the area of nanoscience and nanotechnology.
聚合物基纳米纤维在组织工程、环境监测、食品包装和微/纳米机电系统等各个领域都有应用。这些纳米纤维经过化学处理和恒定应力,使用时可能会导致纤维永久变形。因此,明确定义的纳米纤维的合成和表征技术是确定合适应用所需的化学和物理性质的关键因素。已经开发了许多方法来制备单个纳米纤维,包括静电纺丝、相分离、模板合成和自组装。其中,自组装提供了简单、高效和低成本的策略,可以利用非共价相互作用(包括氢键、静电相互作用、π-π相互作用和疏水相互作用)生产高有序的纳米比尔。综述的第一部分提供了详细的分子相互作用和模拟,可以对其进行控制,以实现明确定义的单个纳米纤维的形成。综述的第二部分描述了表征单个纳米纤维化学和物理性质的各种现有工具,包括原子力显微镜。在综述的最后部分,介绍了最近开发的测量纳米纤维机械性能的新型纳米工具。通过弥合分子相互作用和由此产生的纳米纤维之间的差距,物理和化学性质可能导致在纳米科学和纳米技术领域构建新型纳米材料。

Graphitic carbon nitride (g-C3N4) is an important photocatalytic material that receives a lot of research attention globally. This is because of its favourable thermal and chemical stability as well as electronic band structure. However, the photocatalytic performance of the bulk g-C3N4 is limited by fast recombination of electron-hole pair and poor visible light-harvesting ability. Thus, different strategies, such as heterostructuring, nanotuning, doping, etc., have been adopted to overcome the aforementioned challenges to enhance the photocatalytic performance of g-C3N4. In recent times, various nanostructured g-C3N4 photocatalytic materials with various tuned morphologies have been designed and fabricated in literature for different photocatalytic activities. This mini-review summarized the progress development of nanostructured g-C3N4 photocatalysts with various tuned morphologies for solar fuel generation. The article briefly highlights the research status of various g-C3N4 with tuned morphologies and enhanced solar fuel generation abilities. Finally, a conclusion and future research were also suggested, opening up new areas on g-C3N4 photocatalysis.
石墨碳氮化物(g-C3N4)是一种重要的光催化材料,在全球范围内受到广泛的研究关注。这是因为它具有良好的热稳定性和化学稳定性以及电子能带结构。然而,块状g-C3N4的光催化性能受到电子-空穴对快速复合和较差的可见光捕获能力的限制。因此,已经采用了不同的策略,如异质结构、纳米调谐、掺杂等来克服上述挑战,以提高g-C3N4的光催化性能。近年来,文献中针对不同的光催化活性设计和制备了各种具有不同形貌的纳米结构g-C3N4光催化材料。本文综述了用于太阳能发电的具有各种调谐形态的纳米结构g-C3N4光催化剂的进展。本文简要介绍了各种具有调谐形态和增强太阳能燃料发电能力的g-C3N4的研究现状。最后,还提出了结论和未来的研究方向,为g-C3N4光催化开辟了新的研究领域。

Layered silicates (nanoclay) are new types of nanomaterials derived from clay minerals with wide range application in different fields such as catalysts, soil industry and etc. Nanoclays are wide ranges of naturally occurring inorganic minerals with different derivatives. Montmorillonite is a well-known nanoclay consisting of 2:1 layered structure with two-silica tetrahedron sandwiching an alumina octahedron. In nature, nanoclays can be found in both crystalline (phyllosilicates) and non-crystalline (imogolite) forms. . Nanoclays incorporated into polymer matrices have demonstrated a significant capability to improve the tensile and barrier properties of soil. Nanoclays play a vital role in enhancing soil quality due to its high surface area and porous structure. On the other hand, due to the positive charge of sand grains and the chemical compositions of clay particles, the negatively charged clay particles help to create a good condition to improving soil properties. According to the best of our knowledge, there is not any review paper for study the role of nanoclays on soil samples.

层状硅酸盐(纳米粘土)是由粘土矿物衍生而来的新型纳米材料,在催化剂、土壤工业等不同领域有着广泛的应用。纳米粘土是一种具有不同衍生物的天然无机矿物。蒙脱石是一种众所周知的纳米粘土,由2:1的层状结构组成,两个二氧化硅四面体夹着一个氧化铝八面体。在自然界中,纳米粘土既有结晶形式(层状硅酸盐),也有非结晶形式(伊莫戈莱特)。掺入聚合物基质中的纳米粘土已证明具有显著的改善土壤拉伸和阻隔性能的能力。纳米粘土由于其高表面积和多孔结构,在提高土壤质量方面发挥着至关重要的作用。另一方面,由于砂粒的正电荷和粘土颗粒的化学成分,带负电荷的粘土颗粒有助于创造改善土壤性质的良好条件。据我们所知,目前还没有任何关于纳米粘土在土壤样品中作用的综述论文。本文介绍了纳米粘土化合物在改善土壤样品性能方面的作用,并介绍了土壤样品中使用的不同类型的改性纳米粘土。研究结果表明,具有复杂结构的纳米粘土是改善土壤样品质量的有用纳米材料。

To propose a modified RESS method of herbal pharmaceutical extracts nanoparticle production. A vast number of methods have been applied to water-insoluble pharmaceuticals to improve their solubility. Nanoparticle production of pharmaceuticals is considered as one of the high-speed ways to improve solubility. Supercritical CO2 was applied to extract Zingiber officinale Roscoe rhizome pharmaceutical. Then a modified RESS (rapid expansion of supercritical solution) method, called ESS (expansion of supercritical solution), was exerted to obtain NPs (nanoparticles) of the extracted pharmaceuticals. Initially, applying high pressure in supercritical CO2 contributed to the extract dissolution such that supercritical CO2 was saturated with the sample. Then by decreasing the pressure, an expansion occurred in the saturated medium. This expansion reduced the power of supercritical CO2 solvent and induced the sample nanoparticle nucleation in the needle valve. Unlike rapid expansion of supercritical solution methodology, in this technique, the initial and secondary pressures were permanently above the critical pressure to provide a gentle expansion, which contributes to the production of uniform and small particles. The obtained uniform NPs had a narrow size distribution. Consequently, ESS technique can be considered as an efficient technique for improving the solubility of hydrophobic pharmaceuticals such as [6]-gingerol.
提出一种改进的RESS法生产草药提取物纳米颗粒。大量的方法已应用于水不溶性药物,以提高其溶解度。药物的纳米颗粒生产被认为是提高溶解度的高速途径之一。采用超临界CO2萃取法提取生姜根茎药物。然后采用改良的超临界溶液快速膨胀法(RESS),即超临界溶液膨胀法(ESS)来获得所提取药物的纳米颗粒。最初,在超临界CO2中施加高压有助于萃取物的溶解,使超临界CO2与样品饱和。然后通过降低压力,在饱和介质中发生膨胀。这种膨胀降低了超临界CO2溶剂的功率,诱导了针阀中样品的纳米颗粒成核。与快速膨胀的超临界溶液方法不同,在该技术中,初始压力和二次压力永久高于临界压力,以提供温和的膨胀,这有助于产生均匀和小的颗粒。所得均匀NPs的尺寸分布较窄。因此,ESS技术可以被认为是提高[6]-姜辣素等疏水药物溶解度的有效技术。

Cancer continues to be the most annihilating illness and despite vast research in understanding cancer biology as well as rational drug designing progressing profoundly, cancer remains the second leading cause of death worldwide. The conventional chemotherapeutic agents being exploited for cancer therapy contain several limitations, including less selectivity, nonspecific targeting and high off-target effects, and the emergence of multidrug resistance. These drawbacks can be addressed by employing the use of nanotherapeutics.The main objective of this review is to summarize various mechanisms of cancer genesis. It focuses on several strategies employed for modifying nano formulations for localization and emerging stimuli-based nanotherapeutics with recent examples. The method involved the collection of the articles from different search engines like Google, PubMed, and ScienceDirect for the literature to get appropriate information regarding the topics.Studies revealed that nanoscale-based therapy provides targeted delivery, minimizes the off-target effects, and improves the therapeutic efficacy of the treatment modalities. The characteristics of nanoparticles like larger surface area become favourable and provide a platform for surface modifications, thereby improving cell targeting, internalization, and opportunities for delivering multiple agents. Advances in rational designing like stimuli-responsive therapies employing the use of sensitive nanocarriers, further provide high specificity, controlled release, and more efficient delivery of chemotherapeutic agents.Characteristics of the nanoscale delivery system like larger surface area provide us with ample options for desired modifications, hence providing multimodal delivery of chemotherapeutic agents in cancer treatment. Nano therapy serves well as a potential tool for improving cancer therapies.
癌症仍然是最致命的疾病,尽管在理解癌症生物学和合理药物设计方面的大量研究取得了深刻进展,但癌症仍然是全球第二大死亡原因。用于癌症治疗的传统化学治疗剂存在一些局限性,包括选择性低、非特异性靶向和高脱靶效应,以及多药耐药性的出现。这些缺点可以通过使用纳米疗法来解决。本文的主要目的是总结癌症发生的各种机制。它重点介绍了几种用于修饰纳米制剂以进行定位的策略,以及新兴的基于刺激的纳米疗法和最近的例子。该方法包括从谷歌、PubMed和ScienceDirect等不同搜索引擎收集文章,以获取有关主题的适当信息。研究表明,基于纳米尺度的治疗提供了靶向递送,最大限度地减少了脱靶效应,并提高了治疗模式的疗效。纳米颗粒的较大表面积等特性变得有利,并为表面修饰提供了平台,从而改善了细胞靶向、内化和递送多种制剂的机会。使用敏感的纳米载体进行合理设计类刺激反应疗法的进展,进一步提供了高特异性、可控释放和更有效的化疗药物递送。纳米级递送系统的特征,如较大的表面积,为我们提供了足够的选择来进行所需的修饰,因此在癌症治疗中提供了化疗剂的多模式递送。纳米治疗是改善癌症治疗的一个潜在工具。

The work investigates the performance of intrinsic layers with and without band-gap tailoring in single-junction amorphous silicon-based photovoltaic cells. The work proposes single-junction amorphous silicon solar cells in which band-gap grading has been done between layers as well as within each layer for the first time.The samples of hydrogenated amorphous silicon-germanium with different mole fractions are fabricated, and their band-gaps are validated through optical characterization and material characterization. A single-junction solar cell with an intrinsic layer made up of hydrogenated amorphous silicon (aSi:H) having a band-gap of 1.6 eV is replaced by continuously graded hydrogenated amorphous silicon-germanium (aSi1-xGe x :H ) intrinsic bottom layers having band-gaps ranging from 0.9 eV to 1.5 eV. The proposed structure has been considered as a variant of previously designed single-junction band-gap tailored structures. The suitable utilization of band-gap tailoring on the intrinsic absorber layer aids more incident photons in energy conversion and thereby attain a better short circuit current density of 19.89 mA/cm2.A comparative study on performance parameters of solar cell structures with graded band-gap intrinsic layer and the ungraded single band-gap intrinsic layer has been done. The graded band-gap intrinsic layer structure results in better conversion efficiency of 15.55%, while its ungraded counterpart contributes only 14.76 %. Further, the proposed solar structure is compared with the performance parameters of recent related works. The layers used in the proposed solar structure are of amorphous-phase only, which reduces structural complexity. The use of a lesser number of active layers reduces the number of fabrication steps and manufacturing cost compared to state-of-the-art.
该工作研究了单结非晶硅基光伏电池中带隙剪裁和不带隙剪裁的本征层的性能。这项工作首次提出了单结非晶硅太阳能电池,其中在层之间以及每层内进行了带隙分级。制备了不同摩尔分数的氢化非晶硅锗样品,并通过光学表征和材料表征对其带隙进行了验证。具有由带隙为1.6eV的氢化非晶硅(aSi:H)组成的本征层的单结太阳能电池被带隙范围为0.9eV至1.5eV的连续分级氢化非晶锗(aSi1-xGex:H)本征底层所代替。所提出的结构被认为是先前设计的单结带隙定制结构的变体。在本征吸收层上适当利用带隙剪裁有助于更多的入射光子进行能量转换,从而获得19.89mA/cm2的更好短路电流密度。分级的带隙本征层结构产生了15.55%的更好的转换效率,而其未分级的对应物仅贡献了14.76%。此外,将所提出的太阳能结构与最近相关工作的性能参数进行了比较。所提出的太阳能结构中使用的层仅为非晶相,这降低了结构的复杂性。与现有技术相比,使用较少数量的有源层减少了制造步骤的数量和制造成本。
