제목 Immobilization of Tungsten Catalyst in Processing Microreactors Based Catechol Chemistry for Photothermal Killing of Bacteria
초록 Herein, an antibacterial polydimethylsiloxane (PDMS) microreactors immobilized with Tungsten bronze-type compound of Cs0.33WO3 based on catechol chemistry. Specifically, catechol was grafted into poly(N-vinylpyrrolidone) polymer backbone to create CA-PVP for controlling the adhesive properties on the coated surface. After treated with bacteria, the microreactor showed excellent antibacterial activity after near-infrared (NIR) irradiation during 30-days operation. The Cs0.33WO3 nanoparticles were confirmed not to be stabilized inside the channels, showing the robust immobilization of photothermal agents using excellent adhesive ability of catechol. The immobilized Cs0.33WO3 inside microreactors could be removed easily by acid solution, confirming the recycling ability of the microreactors.
