Near-infrared photothermal activation of microgels incorporating polypyrrole nanotransducers through droplet microfluidics†
Abstract
Poly(N-isopropylacrylamide) (pNIPAM) composite microgels incorporating polypyrrole (PPy) nanoparticles were produced using droplet microfluidics. The composite microgels exhibited site-specific de-swelling–swelling properties that were activated by near-infrared light. Their applications for programmable drug release by pulsed-light control were also demonstrated.
