제목 Immobilization of CsWO3 in Continuous Flow Microreactors by Mussel-Inspired Chemistry for Simultaneous NIR-Mediated Antibacterial Based Photothermal Agents
초록 Here, we successfully prepared an antibacterial continuous flow microreactor by functionalizing mussel-inspired surface engineering of catechol-grafted poly(N-vinyl pyrrolidone) to immobilize of near-infrared active CsWO3 nanoparticles inside the polydimethylsiloxane(PDMS)-based microreactors. The microreactors shows eminent antibacterial acitivity based heat conversion over 99.9% was accomplished toward gram-positive and -negative bacteria upon near-infrared irradiation during continuous operation up to 30 days. This approaching expose that the CsWO3 nanoparticles is stable, without releasing from the surface of the microchannels by strong immobilization through the mussel-inspired chemistry. In conclusion, our microchanels can be widely extendable for the construction of various nanocatalyst- or photocatalyst-immobilized microreactors which are important in many applications such as water disinfection, photodegradation of organic pollutants from water, etc
