nanoparticles

The paper describes the results of experimental work of students and post­graduate students of the Department of Biophysics of the FNP SSU and the laboratory of nanobio­technology IBPPM RAS to identify the potential danger of plasmon­resonance nanomaterials in biomedical research, namely the development of software and instrument complex spectrophotometric and microscopic measurements to estimate viability of microalgae Dunaliella salina and determine the toxicity of the components of incubation medium.

This article was prepared on the basis of a lecture for higher forms students on school-conference «Nonlinear days in Saratov for youth – 2011». The lecture discusses about the results of the experimental work on the use of gold plasmon-resonance particles in cytological studies of undergraduate and graduate students of the basic Chair of biophysics of DNP SSU and Laboratory of nanobiotechnology of IBPPM RAS. Some of the optical properties of gold nanoparticles are discussed to ensure their use for diagnostics and therapy of malignant tumors (cancer cells).
