Effect of Surface Charge on a Microsphere on the Stability of a Nanoparticle Suspension
Shruthi S. Iyengar,
Sarbari Bhattacharya
Abstract:A stable suspension of nanoparticles is generally achieved by modifying the surface properties of the nanoparticles using a surfactant. This is to create a surface charge on the nanoparticles which prevents them from forming aggregates. This phenomenon is very sensitive to changes in the local environment. Conventional optical tweezers though capable of trapping sub‐micrometer particles are not known to trap single nanoparticles. However, the stability and dynamics of a suspension of nanoparticles can be probe… Show more
