RESUMO
Managing bacterial pathogens in the central nervous system is an immense issue for researchers all around the globe. The problem of these infections remains throughout the population, regardless of the discovery of several possible medicines. The major obstacle to drug delivery is the BBB, but only a few medicines that fulfill demanding requirements can penetrate it. Considering inadequate antibiotic alternatives and the increasing development of resistance, it is more important than ever to find new approaches to address this worldwide problem. Medical nanotechnology has evolved as a cutting-edge and effective means of treating many of the most difficult CNS illnesses, including bacterial meningitis. Various metallic nanoparticles, such as gold, silver, and titanium oxide, have shown bactericidal potential. Gold nanoparticles have gotten a great deal of interest due to their excellent biocompatibility, simplicity of surface modification, and optical qualities. The current study described AuNP-based detection and therapy options against meningitis-- causing bacteria, including bacterial pathogens' mechanisms for crossing BBB and AuNPs' mode of Action against those bacteria. The current study looked into green synthesized bactericidal gold nanoparticles-based therapy techniques for diagnosing and intervening in bacterial meningitis. Nevertheless, more research is needed before these laboratory findings can be translated into therapeutic trials. Nonetheless, we can confidently assert that the knowledge acquired and addressed in this study will benefit neuro-nanotechnology researchers.
