Antibacterial analysis and characterization of endotrachal probe of polyvinyl chloride with silver nanoparticles

Abstract

"This article was performed deposition of silver nanoparticles in an endotracheal tube of polyvinyl chloride (PVC) and was evaluated it antibacterial activity; synthesis of silver nanoparticles was performed by an electrochemical method, for which silver nitrate (AgNO3) was used as precursor agent, glucose (C6H12O6) as a reducing agent and sodium hydroxide (NaOH) as a stabilizing agent, to deposit nanoparticles PVC probe in a process of functionalization was performed with two coupling agents, 3-mercaptopropyl trimethoxysilane (C6H16O3SSi) and 3-aminopropyl triethoxysilane (C9H23NO3Si) incorporating nanoparticles was by direct immersion, the product was characterized by infrared spectrometry Fourier transform (FTIR) confirming the chemical functionalization on the probe by means of Scanning Electron Microscope (SEM) and Atomic Force microscopy (AFM) the presence of nanoparticles was observed and an average size of 25nm and is determined through testing antibacterial where PVC samples among E.Coli were exposed zones of inhibition were observed material."
