The subject of disease management has undergone a revolution because to nanotechnology, which has created new instruments and unique tactics for focused therapies. The various roles that nanoparticles play in the treatment of diseases are thoroughly examined in this review paper. Nanoparticles have special physicochemical characteristics that make them useful platforms for therapeutic treatments, imaging, and drug administration. This study emphasises the uses of nanoparticles in diverse illness contexts, such as cancer, infectious diseases, neurodegenerative disorders, and cardiovascular ailments, through a methodical consideration of current developments. The research paper also explores challenges associated with nanoparticle-based medicines, including potential toxicity and regulatory barriers. This review contributes to the understanding of how nanoparticles can change the healthcare landscape by offering insights into the current status of nanoparticle research and its possible implications for future disease management techniques.
