Abstract:
The influence factor of silver nanoparticles on the intramolecular processes of deactivation of the electronically excited state of polymethine dyes (PD) of different ionicity has been studied. It has been demonstrated that the optical density forcationic 1 and anionic 2 dyes does not change under the action of the plasmon field of Ag nanoparticles. Whereas an increase in absorbance by almost 18% was observed for neutral dye 3. A decrease in the enhancement in fluorescence intensity in the series of anionic–cationic–neutral dyes was registered upon addition of Ag nanoparticles to their solutio

Abstract:
In this work, the effect of six non-ionic and two anionic surfactants on the characteristics of poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nanoparticles obtained by single emulsion solvent evaporation technique was assessed. The most satisfactory results were obtained when polyvinyl alcohols with relatively low molecular weight were used as a surfactant.
