Structure and supramolecular organization of silver nitrate modified epoxy or amino terminated liquid oligoethers.

The behavior of silver nitrate in non-aqueous liquid oligomeric media-aromatic and aliphatic diglycidyl ethers and aliphatic diamine-has been investigated. By employing UV-visible spectrophotometry and dynamic light scattering, it has been shown that in diglycidyl oligomers, regardless of the nature of the monomeric unit, the formation of silver nanoparticles occurs, and the kinetics of this process has been studied. At the same time, in the medium of aliphatic diamine, the reduction of silver ions is absent, indicating the formation of a complex compound.

Formation Kinetics and Antimicrobial Activity of Silver Nanoparticle Dispersions Based on N-Reacetylated Oligochitosan Solutions for Biomedical Applications.

The paper presents the results of the synthesis, a detailed kinetics study, and an investigation of the biological activity of silver nanoparticles (AgNPs) in aqueous solutions of N-reacetylated oligochitosan hydrochloride. UV-visible spectrophotometry and dynamic light scattering were employed to control silver ion reduction. The process was observed to follow a pseudo-first-order law.
