N2 - The predominant adverse health effects in care delivery result from hospital-acquired (nosocomial) infections, which impose a substantial financial burden on global healthcare systems. Integrating contact-killing antibacterial action, gas permeability, and antioxidant properties into textile coatings offers a transformative solution, significantly enhancing both medical and everyday protective applications. This study presents an innovative, pollution-free physical compounding method for creating a fluorescent biopolymer composite embedded with silicene-based heteroatom-doped carbon quantum dots for the production of functional textiles. The resulting coated fabric shows superior ultraviolet (UV) protection behavior (UVA and UVB), thermal stability, breathability, mechanical strength, and antioxidant capabilities as demonstrated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) experiment (>78%) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) ABTS assay (>90%). Rigorous testing against both gram positive and gram negative bacteria confirms that the coated fabric has excellent antibacterial activity. Results from time-dependent antibacterial assays indicate that the nanocomposite can markedly inhibit bacterial proliferation within a few hours. Molecular dynamics modeling, in conjunction with experimental investigations, is employed to elucidate the intermolecular interactions influencing the components of the treated cotton fabrics. The ongoing research can result in the creation of cost-effective smart textile substrates aimed at inhibiting microbial contamination in healthcare and medical applications, possibly rendering them commercially viable.
