Bactericidal activity of zinc oxide particles embedded in poly(vinyl pyrrolidone) electrospun fibers

Abstract

Composites of metal oxide nanoparticles incorporated into poly(vinyl pyrrolidone) electrospun fibers can be considered potential and low cost bactericidal agents. Homogeneous distribution of nanoparticles in the core of fibers and minimal aggregation induced by strong interaction with polymeric template are factors that contribute with diffusion of metal oxide nanoparticles from bulk to the fiber surface and subsequent release of nanoparticles to bacterial culture. Hybrid electrospun fibers were successfully applied against bacteria as a result of reasonable degree of interaction between zinc oxide and fibers as detected from FTIR analysis, DSC curves and SEM images.

Synthesis of nonylphenol polyoxyethylene oligomer and application as an effective dispersant in pyraclostrobin suspension concentrate

“…In addition, they are highly efficient in lowering interfacial tension and form micelles at very low critical micellar concentrations [15,16]. Based on unique superior performance, they have a great potential of being used as effective emulsifiers, bactericidal agents, dispersants, antifoaming agents, and detergents [17][18][19][20]. Trimeric nonionic surfactants are also used in the oil industry recently, and the most of the work is focused on enhanced oil recovery.…”
