Conventional surgical gloves often fail to protect against bacteria and viruses, tearing easily and exposing surgeons and patients to infection risks. To address this, researchers developed eco-friendly chitosan nanoparticle-coated surgical gloves with enhanced antibacterial and antiviral properties. Chitosan, derived from crustacean shells, is biocompatible, biodegradable, and antimicrobial. The coated gloves showed over 99% bacterial inhibition against four strains, including Pseudomonas aeruginosa. Strong antiviral activity against HIV and hepatitis B virus. Improved mechanical performance: Tensile strength increased from 3.85 KN/mm (untreated) to 12.09 KN/mm (coated). Elongation at break increased from 777.8% (untreated) to 822% (coated). These enhancements can reduce tears and contamination, improving healthcare safety. The use of chitosan nanoparticles offers a promising solution for infection control in surgical settings. This innovation has potential to significantly impact healthcare practices, providing better protection for medical professionals and patients.
