Three types of semiconductor CdS nanoparticles (quantum dots) are obtained by biosynthesis, using bacteria Escherichia coli, the fungus Pleurotus ostreatus, and the plant — Linaria maroccana. The effects of CdS quantum dots on the cancer cell line HeLa is studied. All types of CdS quantum dots vs ionic Cd2+ have weaker cytotoxic and cytostatic activities. The effects on cells’ adhesive potential depend on the types of CdS quantum dots. The least toxic quantum dots are synthesized, using the fungus Pleurotus ostreatus. Low toxic effects of studied fluorescent CdS nanoparticles on cancer cells might promise their effective application to cell biology and biomedical research.
