Single-chain polymer nanoparticles via reversible disulfide bridges

Abstract

We report the fabrication of single-chain polymer nanoparticles (SCNP) that can reversibly undergo a coil to particle transition via formation and cleavage of intramolecular disulfide cross-links. Characterization of this behaviour via shifts in SEC retention time confirm the changes in solution conformation in response to oxidative or reductive stimuli.
