Postoperative bacterial infection of polyetheretherketone (PEEK) medical implants remains a difficult clinical problem
.
Recently, Deng Yi's team from the School of Chemical Engineering of Sichuan University, based on the previous research on medical special PEEK polymer implants and surface interfaces, developed a new kind of two-dimensional emerging MXene nanosheets and one-dimensional cobalt nanowires for the above key scientific issues.
(CoNWs) composed of near-infrared light-activated bioheterojunction coatings for combating drug-resistant bacteria (Fig.
1)

The photothermal and photodynamic effects of Ti3C2/CoNWs coating triggered by near-infrared light can kill Gram-positive Staphylococcus aureus/Gram-negative Escherichia coli within 20 minutes, achieving more than 90% antibacterial effect (Figure 2)
