The swift increase in antimicrobial resistance across the world presents a significant challenge, further raised by insufficient advancement design of new agents. Over past two decades, variety sources has been investigated for generating antimicrobials. Recently, polymers (APs) have emerged as multifaceted agents, displaying effectiveness against range pathogens such bacteria, fungi, and viruses. Their notable biocompatibility, efficiency, multifunctionality, ease modification make them focal point research. APs are particularly valued their structural versatility, which allows integration functional groups. Polymer functionalization does not only enhance or introduce properties but also maintains high levels biocompatibility. This review reveals broad breadth APs, can be potentially used antiseptics, food packaging, biomedical sector, e.g. medical implants' coatings. In laboratory settings, shown promising therapeutic effects, however there remains an urgent need computational biology to fully understand behaviour stability. Recombinant biotechnological approaches essential facilitating production require industrial collaboration effectively optimize scale up these processes.
