One of the key factors contributing to mortality and morbidity globally is infectious ailments. According to
recent statistics from WHO, amplified antimicrobial resistance occurrence among bacteria signifies the utmost threat to
global public health. Bacteria have developed various strategies to resist antimicrobials, including enzymatic inactivation of antibiotics, drug efflux, modifications of the antibiotic molecule or chemical alteration of the antibiotic, limited
drug uptake, etc. Furthermore, the inefficiency of antimicrobial drugs against resistant bacteria due to low solubility,
instability, and associated side effects augments challenges to combat these resistant pathogens. This has attracted the
attention of researchers to create nano-delivery and targeting techniques. This review presents an overview of antimicrobial resistance (AMR), its various subtypes, as well as mechanisms involved in AMR. This review also describes
current strategies and applications of various nanocarriers, including nanoparticles, liposomes, lipid-based nanoparticles, micelles, and polymeric nanoparticles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
