摘要: At present there are few methods available for observing the adhesion of viruses. Also, it is difficult to determine virus concentrations on-line. This paper describes “NanoSight,” a microscope instrument which counts nanoparticles directly from scattered laser light and then determines their diameter by tracking Brownian movement applying Stokes-Einstein theory random walk pathways. By this preparations adenovirus, concentration viruses has been measured compared with polystyrene latex spheres. Then, used detect aggregates in suspension. Taking number as measure interparticle equal spheres, self-adhesion particles estimated function two parameters, energy range interaction. The results showed that was similar polystyrene.
