An antibacterial continuous flow microreactor was successfully prepared by sequential mussel-inspired surface engineering of microchannels by using catechol-grafted poly(N-vinylpyrrolidone) and immobilization of near-infrared active Cs0.33WO3 nanoparticles inside the polydimethylsiloxane(PDMS)-based microreactors. Excellent phothothermal antibacterial(More)
In this study, a new hydrophilic-hydrophobic transition surface was designed via visible-light-induced photocatalytic perfluorinated silica-based fluorescent carbon nanoparticles (FNPs)/TiO2. Perfluorinated silica-polydopamine hybrid FNPs (f-FNPs) were easily fabricated by carbonization in an emulsion system consisting of tetraethyl orthosilicate and(More)
Highly fluorescent and amphiphilic carbon quantum dots (CQDs) were prepared by microwave-assisted pyrolysis of citric acid and 4,7,10-trioxa-1,13-tridecanediamine (TTDDA), which functioned as an A3 and B2 polyamidation type monomer set. Gram quantities of fluorescent CQDs were easily obtained within 5 min of microwave heating using a household microwave(More)
In this communication, we present a new synthesis method for the fabrication of hybrid metal-Cu2S (M = Pt, FePt) nanocrystals (HNs). The metal-Cu2S HNs were investigated in photocatalytic hydrogen generation as effective co-catalysts on TiO2. The Pt-Cu2S/TiO2 catalyst showed a higher hydrogen generation rate compared with a pure TiO2 catalyst. This(More)
