Near-Infrared-Activated MoS2(S)–Ag3PO4 Coating for Rapid Bacteria-Killing

Medical tools and implants used in clinics can be contaminated with bacteria even disinfection treatment. To avert this situation, titanium (Ti) plates modified a MoS2(S)–Ag3PO4 coating were designed to kill Staphylococcus aureus (S. aureus) Escherichia coli (E. coli) effectively under near-infrared (NIR) light irradiation. The introduction of Ag3PO4 nanoparticles (NPs) reduced the bandgap MoS2 suppressed recombination photogenerated electron–hole pairs. Therefore, Ti–MoS2(S)–Ag3PO4 exhibited higher photocatalytic performance, leading generation more radical oxygen species (ROS). Furthermore, cooperating good photothermal performance MoS2, high antibacterial efficacy 99.76 ± 0.15% 99.85 0.09% against S. E. coli, respectively, for 15 min vitro. Moreover, had no apparent toxicity cells. proposed strategy may provide new insights rapidly eradicating on medical superficial implants.
