Autor: Kirill Khabarov, Emiliia Filalova, Messan Nouraldeen, Ekaterina Kameneva, Andrey Musaev, Sergei Tikhonov, Victor Ivanov

Publikováno v: Nanomaterials, Vol 13, Iss 5, p 812 (2023)

An analyzed substance’s signal intensity and detection sensitivity in surface-enhanced Raman spectroscopy (SERS) significantly depend on the size and agglomeration degree of nanoparticles (NPs) forming the enhancing structure. Structures were manuf
