Biofilm-associated infections present a significant challenge in modern medicine, primarily due to their resilience and resistance conventional treatments. These occur when bacteria form biofilms, protective layers formed by bacterial communities, which are notoriously resistant traditional antibiotics on surfaces such as medical implants biological surfaces, making eradication with standard difficult. This leads persistent infections, imposing substantial economic burden healthcare systems. The urgency find alternative treatments is critical current methods insufficient costly. Innovative approaches, nanotechnology-based therapies, offer promising alternatives targeting biofilms more effectively reducing the need for invasive procedures. Nanocarriers hold promise fight against biofilm-associated infections. can penetrate than treatments, delivering higher concentrations of or other antimicrobial agents precisely where they needed. targeted approach not only enhances efficacy but also minimizes potential side effects. development nanocarrier-based therapies crucial overcoming limitations ultimately improving patient outcomes In this review, systems, characteristics, limitations, benefits explored address biofilms-related Additionally, biofilm evaluation models tests necessary preclinical validation these nanosystems facilitate clinical application addressed.

Microbial infections are a pressing global health issue, exacerbated by the rise of antibiotic-resistant bacteria due to widespread antibiotic overuse. This resistance diminishes effectiveness current treatments, intensifying need for new antimicrobial agents and innovative drug delivery strategies. Nanotechnology presents promising solutions, leveraging unique properties nanomaterials such as tunable optical electronic characteristics, nanoscale size, high surface-to-volume ratios. These features enhance their versatile systems. minireview classifies into four categories based on mechanisms action: thermal generation, reactive oxygen species gas nanocarrier systems liposomes, polymersomes, metal-organic frameworks. Uniquely, this review integrates comparative analysis these mechanisms, highlighting relative advantages, limitations, applications across diverse microbial targets. Additionally, it identifies emerging trends in field, providing forward-looking perspective how recent advancements nanotechnology can be leveraged address unmet clinical needs. Finally, article discusses future directions opportunities nanotechnology.
