This paper performs detailed study of Raman scattering for platelets mixed with gold nanoparticles in presence with R6G molecules on quartz surface. Spectral properties of main spectral bands corresponding to proteins and dye in the complexes with gold nanoparticles have been performed. The perspectives SERS for applications in modern physics and biophotonics have been shown. Results of the study can be applied for SERS detection and investigation of blood components such as cells and platelets. Paper describes characteristic maxima of different cell components and its identification in platelets.
The article presents the results of the SERS study of fluorine-containing dye 6G (R6G) adsorbed onto quartz surfaces modified with gold nanoparticles (NPs). A new technique for quartz glass modifying with hydrosols of gold NPs of various shapes has been developed. The possibilities of its application to implement SERS effect for R6G molecules have been shown. In this work, we synthesized hydrosols of spherical gold NPs (nanospheres) and rod-shaped NPs (nanorods (NRs)) and studied their optical and morphological properties. The SERS spectra of R6G molecules on NP modified quartz glasses have been obtained as well as the SERS enhancement factor has been calculated.
