Abstract
The unprecedented upsurge of human suffering, whose canvas seems to broaden by the emergence of incurable diseases as a result of evolution of novel strains of microbes is further compounded by the development of antimicrobial resistance, growing urbanization and lifestyle. Nanomaterials are of nano size-ranging from 10–100 nm, and nowadays, they are finding immense applications in drug delivery owing to their advantages over the conventional drug delivery systems. This review article aims to discuss various types of nanomaterials including polymeric nanoparticles (polymersomes, dendrimers, polymer micelles, nanospheres, and nanogels), inorganic nanoparticles (SiNPs, quantum dots, MXenes, FeONPs, and AuNPs) and lipid-based nanomaterials (liposome, lipid nanoparticles, emulsions, and niosomes) in drug delivery applications. Besides this, the manuscript also discusses their limitations, suitability, theranostics, and safety concerns in drug delivery. From the discussion about their applications and limitations in drug delivery, it can be conclusively stated that because of their versatility, the nanomaterials are promising contenders in the field of nanomedicine and their utility in healthcare has convincingly endorsed the fact that however ‘nano’ the dimensions of nanomaterials are, they have colossal relevance.
