Abstract:
Real-time dynamics of native super-paramagnetic nanoparticles (SPMNPs) with different sizes were observed in a microchip at the single-particle level. Based on the optimized magnetic field conditions obtained in the single-nanoparticle study, the SPMNPs were successfully separated and detected within ~15 s from the model polydisperse mixture.
