Abstrakt: We use atomic-force microscopy, transmission electron microscopy, ultraviolet (UV)/visible spectroscopy, and dynamic light scattering to perform a comparative study of new hybrid bioactive nanosystems based on nanoparticles of various natures: zero-valent copper (Cu0), zero-valent selenium (Se0), and zero-valent silver (Ag0) stabilized with a water-soluble homopolymer poly-4-acryloylmorpholine (PAM). We demonstrate the possibility of regulating the structural and morphological parameters and the dimensional and spectral characteristics of bioactive nanosystems by varying the nature of nanoparticles. The reduction of ions of biogenic elements in water in the presence of poly-4-acryloylmorpholine, due to sufficiently good screening, yields spherical nanostructures with a diameter not exceeding 180 nm (PAM/Se0). The most probable sizes of nanoparticles do not exceed 12 nm. [ABSTRACT FROM AUTHOR]
