Characterization of Silica Nanoparticles in Interaction with Escherichia coli Bacteria

Year: 2013 Volume: 7 Issue: 7 536 - 542 Pages

Abstract: The objective of the present investigation was to evaluate the morphology of Escherchia coli bacteria in interaction with SiO2 nanoparticles. This study was made by atomic force microscopy and quartz crystal microbalance using SiO2 nanoparticles with 10nm, 50nm and 100nm diameter and bacteria immobilized on polyelectrolyte multilayer films obtained by spin coating or by “layer by layer” (LbL) method.
