An AgCuTe nanowire composite material, its preparation method, and its application in medical antibacterial gauze are disclosed. The material consists of two phases: Cu7Te4 and Ag2Te, exhibiting a one-dimensional nanowire morphology with uniform silver distribution and nanowire diameters ranging from 7 to 9 nm. This material is prepared via a tellurium nanowire template combined with a two-step liquid-phase displacement reaction. First, tellurium nanowires are synthesized hydrothermally, followed by sequential reactions with copper and silver sources at room temperature to obtain the product. The AgCuTe nanowires exhibit concentration-dependent and power-dependent photothermal heating effects under 808 nm near-infrared light irradiation, with good photothermal stability. Under near-infrared light irradiation, the material demonstrates significant synergistic antibacterial activity against Staphylococcus aureus and Escherichia coli. Loading this material onto medical gauze can produce a near-infrared responsive photothermal antibacterial dressing for wound care and infection control, without antibiotic dependence, thus helping to reduce the risk of bacterial resistance.
