Fluorescence Imaging For Ultrafiltration Of Individual Nanoparticles From A Colloidal Solution In Track Membranes

2018
Journal paper
Abstract

We have used fluorescence nanoscopy for direct imaging of adsorption of individual colloidal quantum dots of diameter similar to 10 nm (spherical core/shell CdSeS/ZnS semiconductor nanocrystals, functionalized by organic oleic acid ligands) in nanopores of a nuclear filter (a polypropylene track membrane with pores of diameter similar to 500 nm). We have shown that when a colloidal toluene solution passes through the pores of the membrane, the nanoparticles are completely retained at a depth of 10 mu m.
