Nanotechnology and Drug Delivery: Recent Applications and Future Challenges

Abstract

Today, nanotechnology has paved the way for developing a new generation of delivery systems for potential drugs, proteins, peptides, and genes of interest. This effort reviews a couple of recent reports on application of gold nanoparticles in protein/peptide delivery, with a glance at toxicological aspects of nanoparticles and potential challenges in the upcoming future. Highlights • Advances in nanotechnology have revolutionized fabrication and development of novel materials with diverse theranostic applications. • Gold nanoparticles (GNPs) have been nominated as promising candidates in delivery of protein and peptide drugs. • A deep understanding of biological responses to bare nanoparticles and their complex form is a prerequisite to produce low risk hybrid nanocarrier systems.
