Research work is devoted to the development of "green" (environmentally sensitive) methods of synthesis of CdTe quantum dots using the mycelium of the basidial fungus Pleurotus ostreatus, study of their physico-chemical characteristics, as well as the development of methods for their application.Spectral characteristics of biosynthetic CdTe nanoparticles were investigated using optical spectrophotometry methods. The structure and morphology of CdTe nanoparticles were investigated by transmission electron microscopy. Тoxicity of chemically synthesized CdTe quantum dots on human T-and B-lymphocytes, endothelial cells, coloncancer cells (Colo 205) and human mammary gland (MCF-7) has been evaluated.Screening of chemically synthesized CdTe quantum dots indicates toxicity of these nanoparticles in a range of concentrations that exceed limit concentrations of similar nanostructures. CdTe nanoparticles obtainedby a fungal mycelium have a lower toxic effect compared to chemically synthesized particles, which is probably due to the presence of an organic shell around the nucleus of such quantum dots.
