Abstract
The invention relates to a SERS method for analyzing a biological sample, the method comprising the following step of: a. obtaining a biological sample which is viscous biofluid, b. depositing at least one droplet of the biological sample onto a microscope slide, and drying the droplet, c. depositing a drop of an aqueous dispersion of metallic nanoparticles above the droplet dried in step b), to have a dense distribution of nanoparticles on the surface of the dried droplet and to obtain a SERS-activated biological sample, d. drying the SERS-activated biological sample, e. irradiating the SERS-activated biological sample using a light source to obtain a SERS spectrum, and f. collecting the SERS spectrum.
