The Role of Primary Acts of Ion Reduction and Oxygen Effects Using Various Methods of Gold Nanoparticle Formation, Including Self-Assembly
This work presents the results of a study of the physical-chemical properties of gold nanoparticles (NP) prepared in reverse micellar solutions (RMS) using various ion reduction methods, including self-assembly (SA). The spectra of the electron plasmon resonance of the Au NP in the visible region (λmax ~ 530 nm) and in the UV region of the spectrum (λmax ~ 200–220 nm) were recorded by UV–Vis spectrophotometry. In the present work, the kinetics of the primary stages of the formation of Au NPs in RMS using various synthesis methods, including SA, has been studied. Based on the results we obtained, an explanation has been provided for the effect of oxygen (aerobic conditions) on the primary stages of the formation of Au NPs using chemical (Chem) synthesis in the presence of the flavonoid quercetin, and radiation-chemical (RadChem) one based on interaction with intermediate particles of water radiolysis. The formation of Au NPs with optical absorption bands in the UV region and the visible region of the spectrum has been corroborated by the results of electron microscopy.
