Self‐Controlled Monofunctionalization of Quantum Dots for Multiplexed Protein Tracking in Live Cells

Abstract

Functionalization of quantum dots (QDs) was achieved by controlling the surface density of functional groups by electrostatic repulsion. These QDs were conjugated with His-tagged proteins in vitro and in live cells by self-assembly without requiring further fractionation, and dual-color tracking of cell surface receptors was possible.
