Abstract

In this paper by the methods of Raman spectroscopy, a drop of the evaporating liquid of Human Serum Albumin with the Rhodamine 6G dye molecules in the presence of silver nanoparticles obtained by laser femtosecond ablation in water was studied. In the Raman spectra, an increase in the intensity of scattering of dye molecules with silver nanoparticles the addition of protein molecules was recorded. We suppose that the observed effect is associated with the diffusion and thermal processes in the drop arising during laser excitation.
