Abstract
Targeted therapeutic delivery for treating bacterial infections remains underutilized in most pharmaceutical interventions. Existing therapeutics (i.e., antibiotics) are often systematically administered despite the presence of localized infection, leading to both off-target toxicity and suboptimal bacterial clearance with limited efficacy against biofilms. The overuse of antibiotics has resulted in increased antimicrobial resistance, creating a need for alternative interventions that are unlikely to confer resistance. Nitric oxide (NO), an endogenous mediator produced by macrophages and other immune cells in response to infection, elicits broad spectrum antibacterial and antibiofilm activity. The use of exogenous NO donors, alone or as conjugated ligands to macromolecular scaffolds, has proven effective in treating anatomical targets, including dermal wounds, dental infections, and pulmonary conditions, in a localized manner. In this perspective, we provide an overview of the recent advancements in NO-releasing biomaterials, highlighting design strategy and antimicrobial action across diverse anatomical sites.
