fCuInS（2）（CIS）纳米粒子具有独特的化学、毒理学和光电性质，有利于其技术应用。在本工作中，我们报告了一种新的一步仿生方法的水相合成CIS纳米粒子，这也是低成本和环境友好。这种仿生方法仅使用CuSO 4和InCl 3作为前体盐，并且生物分子谷胱甘肽作为硫供体和纳米颗粒（NPs）的稳定剂。该反应在低温、有氧条件和大气压下进行。通过我们的仿生方法产生的CIS纳米颗粒在500 nm激发时在650和700 nm之间显示荧光发射。通过动态光散射（DLS）测定10和15 nm之间的尺寸，并通过电子透射显微镜证实。X射线衍射分析（XRD）证实了所产生的CIS NP的晶体结构。能量色散X射线光谱（EDX）分析揭示了Cu、In和S以0.6：1.4：2的比例存在，这在文献中已经报道了其他CIS NP。在人OKT 6/TERT 2细胞和细菌中未观察到CIS NP的细胞毒性。此外，仿生CIS纳米粒子作为光敏剂在量子点敏化太阳能电池（QDSSC）中的潜在应用也得到了证实。通过我们的仿生方法生产的CIS NPs的生物相容性，光谱特性和太阳能电池中的能量收集性能使它们适合于在不同的生物技术应用中使用。(C)2021年，任作者。由Elsevier B.

fCuInS(2) (CIS) nanoparticles have unique chemical, toxicological and optoelectronic properties that favor their technological applications. In the present work we report a novel one step biomimetic method for the aqueous synthesis of CIS nanoparticles, that is also low cost and environmentally friendly. This biomimetic method uses only CuSO4 and InCl3 as precursor salts, and the biological molecule glutathione as sulfur donor and stabilizer of the nanoparticles (NPs). The reaction is performed at low temperatures, under aerobic conditions and atmospheric pressure. CIS nanoparticles produced by our biomimetic method exhibit fluorescence emission between 650 and 700 nm when excited at 500 nm. A size between 10 and 15 nm was determined by Dynamic light scattering (DLS) and corroborated by electron transmission microscopy. X-ray diffraction analysis (XRD) confirmed the crystalline structure of the CIS NPs produced. Energy Dispersive X-Ray Spectroscopy (EDX) analyses revealed the presence of Cu, In, and S in a 0.6: 1.4: 2 ratio, which has been reported for other CIS NPs in literature. No cytotoxicity of CIS NPs was observed in human OKT6/TERT2 cells and bacteria. Besides, the potential application of biomimetic CIS NPs as photosensitizers in quantum dots sensitized solar cells (QDSSCs) was confirmed. The biocompatibility, spectroscopic properties, and energy harvesting performance in solar cells of the CIS NPs produced by our biomimetic method make them suitable for their use in different biotechnological applications.
