Structural-Morphological and Spectral Characteristics Hybrid Bioactive Copper-, Selenium- and Silver-Containing Nanosystems Based on Poly-4-Acryloylmorpholine
By the methods of atomic force (AFM) and transmission electron (TEM) microscopy, UV/visible spectroscopy, and dynamic light scattering (DLS), a comparative study of new hybrid bioactive nanosystems based on nanoparticles (NPs) of various nature: zero-valent copper (Cu<sup>0</sup>), zero-valent selenium (Se<sup>0</sup>) and zero-valent silver (Ag<sup>0</sup>) stabilized by the water-soluble homopolymer poly-4-acryloylmorpholine (PAM) has been carried out. The possibility of controlling the structural and morphological parameters, as well as the dimensional and spectral characteristics of bioactive nanosystems by varying the nature of the NPs was shown. It was established that the reduction of biogenic element’s ions in water in the presence of PAM due to sufficiently good screening allows to obtain spherical nanostructures with a diameter not exceeding 180 nm (PAM/Se<sup>0</sup>). The most probable sizes of NP/nanoclusters do not exceed 12 nm.
