Trends in Nanotechnology for Practical Applications

The document from 2019 provides a comprehensive overview of the advancements in nanotechnology for practical applications, particularly in drug delivery systems. It emphasizes the development of nanoparticle drug delivery systems (NPDDSs) to enhance bioavailability, control drug release, and achieve site-specific targeting, with applications ranging from cancer treatment to gene therapy. The document discusses the use of various nanoparticles, including PEGylated gold nanoparticles, polymeric nanoparticles, and dendrimers, for delivering drugs, proteins, and peptides more effectively. It also explores the challenges of gene delivery, the use of nanoparticles in dermatology for conditions like alopecia, and the incorporation of nanotechnology in cosmetics. Additionally, the document highlights the potential of pulmonary drug delivery for systemic absorption and the development of receptor-specific systems for lung diseases. Despite the promising solutions offered by NPDDSs, the document acknowledges the challenges in maintaining drug delivery to the target site and the need for careful evaluation of the risks associated with nanoparticles.
