A series of metal oxide nanoparticles coated on glass fiber substrates were developed in our research group for evaluation of their viricidal activity. The nanoparticles were prepared with a narrow size distribution and deposited on a glass fiber substrate. They were also characterized by XRD, TEM, surface area measurements and for their zeta potential. MS2 virus inactivation experiments showed that these nanoparticle-coated fibers were powerful viricidal materials. We believe that electrostatic interactions (surface charge) are the primary factor for achieving the inactivation of viruses.
