Capillary Electrophoresis Methods for the Characterization of Synthetic Nanoparticles

open access: yesELECTROPHORESIS, EarlyView.
Capillary electrophoresis (CE) can be applied to evaluate nanoparticle (NP) size, charge, and surface characteristics. Hyphenating CE with ICP‐MS and AF4 can provide comprehensive, multidimensional NP characterization. ABSTRACT Nanoparticles (NPs) exhibit properties distinct from bulk materials of identical chemical composition, with their behavior and
