• The article presents the results of studies of nanocomposite biostrucrures based on a protein matrix, impregnated with carbon nanotubes (CNTs). To prepare the samples, aqueous dispersions of bovine serum albumin (BSA) and bovine collagen (BC), with the addition of two types of single-walled carbon nanotubes (SWCNT) were prepared. Nanocomposite materials were created by the method of layer-by-layer deposition and laser evaporation of the aqueous component from dispersions. As sources of laser radiation, a continuous diode laser with a wavelength of 810 nm, a power of 2 W, and a semiconductor laser with a wavelength of 810 nm were used. Infrared (IR) spectra and Raman spectra of biostructures were obtained and analyzed. The spectra of nanocomposite biostructures demonstrated a high degree of binding of the organic (protein) and inorganic (SWCNT) components. From Raman spectra, the structure and defectiveness of a carbon scaffold was studied.
