Abstract One of the developing areas of nanotechnology is the production and application of nanoscale materials, with large surface/volume ratios, which provides them with the specific properties. Cadmium telluride (CdTe) is a typical nanomaterial, which has been the subject of various studies due to its large bandwidth and excitation binding energy, which make it suitable for various purposes like anti-inflammatory, wound healing, antioxidant, antifungal and antibacterial applications. The large quantities of toxic chemicals and harsh conditions required for preparing CdTe, led to great interest in developing green methods for its synthesis. This review provides a comprehensive overview of the research on the green biological synthesis of CdTe. It is also important to consider the increasing interest in the area of production of CdTe QDs (Quantum dots) for drug delivery, bioimaging and anti-cancer applications. One green approach for producing CdTe nanocrystals is the application of metabolic activity of living organisms. Intra and extra-cellular biosynthesis can occur through a biomimetic approach based on feeding organisms with cadmium and telluride precursors. Yet there are huge gaps in our knowledge on the toxic effects of nano-scale CdTe particles on single organisms and the mechanism there of and to guarantee the safe application of CdTe, further work needs to be done on assessing the long-term effects of nano-sized CdTe particles at low quantities.

使用草药物种和微生物制备的 CdTe 量子点及其抗癌、药物输送和抗菌应用;回顾

摘要 纳米技术的发展领域之一是纳米材料的生产和应用,这些材料具有大的表面积/体积比,使其具有特定的性能。碲化镉 (CdTe) 是一种典型的纳米材料,由于其大带宽和激发结合能,使其成为各种研究的主题,使其适用于抗炎、伤口愈合、抗氧化、抗真菌和抗菌等各种用途。制备 CdTe 所需的大量有毒化学物质和苛刻的条件导致人们对开发其合成绿色方法的极大兴趣。本综述全面概述了 CdTe 绿色生物合成的研究。考虑到对用于药物输送、生物成像和抗癌应用的 CdTe QD(量子点)生产领域日益增长的兴趣也很重要。生产 CdTe 纳米晶体的一种绿色方法是应用生物体的代谢活动。细胞内和细胞外生物合成可以通过基于用镉和碲化物前体喂养生物体的仿生方法发生。然而,我们对纳米级 CdTe 颗粒对单一生物体的毒性作用及其机制的认识存在巨大差距,为了保证 CdTe 的安全应用,需要做进一步的工作来评估纳米级 CdTe 颗粒的长期影响。 - 大小的 CdTe 颗粒数量很少。生产 CdTe 纳米晶体的一种绿色方法是应用生物体的代谢活动。细胞内和细胞外生物合成可以通过基于用镉和碲化物前体喂养生物体的仿生方法发生。然而,我们对纳米级 CdTe 颗粒对单一生物体的毒性作用及其机制的认识存在巨大差距,为了保证 CdTe 的安全应用,需要做进一步的工作来评估纳米级 CdTe 颗粒的长期影响。 - 大小的 CdTe 颗粒,数量很少。生产 CdTe 纳米晶体的一种绿色方法是应用生物体的代谢活动。细胞内和细胞外生物合成可以通过基于用镉和碲化物前体喂养生物体的仿生方法发生。然而,我们对纳米级 CdTe 颗粒对单一生物体的毒性作用及其机制的认识存在巨大差距,为了保证 CdTe 的安全应用,需要做进一步的工作来评估纳米级 CdTe 颗粒的长期影响。 - 大小的 CdTe 颗粒,数量很少。
