Biomaterials for Antibacterial and Antiviral Applications

Biomaterials for antibacterial and antiviral applications are designed to prevent and control infections, a critical concern in medical settings. These materials incorporate active agents or surface modifications that inhibit the growth of bacteria and viruses. Innovations in this field include the development of antimicrobial coatings and impregnated materials used in medical devices such as catheters, implants, and wound dressings. Antibacterial biomaterials often feature coatings with silver nanoparticles, copper ions, or natural compounds like chitosan that exhibit broad-spectrum antimicrobial activity. Antiviral materials may include coatings or particles that disrupt viral replication or bind to viral particles, preventing their attachment to host cells. Recent advancements also explore the integration of responsive elements that release antimicrobial agents in response to environmental triggers, such as infection or inflammation. These smart materials enhance infection control, reduce the need for systemic antibiotics, and contribute to better patient outcomes in clinical settings.
