Nanotechnology in Biomaterials: Revolutionizing Drug Delivery Systems

This is the authors' abstract. We don't add key points for this paper.

Nanotechnology has been a significant scientific development, improving many facets of science, especially medicine. This paper explores the revolutionary impact of nanotechnology on drug delivery systems, emphasizing its ability to address challenges associated with traditional methods, such as low bioavailability, non-specific targeting, and unpredictable drug release. By utilizing various nanomaterials, including lipid-based, polymeric, and inorganic nanoparticles, nanotechnology enables targeted delivery, controlled release, and improved stability of therapeutic agents. The mechanisms of nanoparticle-mediated drug delivery, such as passive targeting via the enhanced permeability and retention effect and active targeting using ligand-directed nanoparticles, are also discussed in detail. Nanotechnology has facilitated various innovations, such as stimuli-responsive nanomaterials that release drugs based on disease-specific stimuli or biocompatible mucoadhesive systems to enhance drug efficacy and reduce side effects. Despite significant challenges nanotechnology faces, including biological complexity, toxicity, and scalability, it holds great promise for the future of personalized medicine and advanced therapies. The article also discusses the challenges and limitations and also provides a future outlook for nanotechnology in drug delivery applications.
