Gold Nanoparticles:A Boon to Drug Delivery System

Gold nanoparticles (AuNPs) are currently playing a significant role for human welfare in the field of clinical diagnosis as well as several biomedical applications. More and more research shows that AuNPs-based technologies are becoming promising approaches in diabetes, cancer research, chemotherapy, AIDS treatmentetc. AuNPs can be easily synthesized, functionalized, and are biocompatible. The tenability of theAuNP monolayer allows for complete control of surface properties for targeting and stability/release using these nanocarriers.Nanoplatforms have been developed to manufacture of nanomedicines in preclinical and clinical studies for the administration of small molecules, genes, and peptides with improvement of given in vivo behaviour. Similarly, NPs emerge as the future of drug delivery technology as they might be future crucial diagnostic and therapeutic tools. Of these, gold nanoparticles with their unique chemical and physical properties have emerge as promising carrier for delivery of various molecules with therapeutic properties.This review will discuss several delivery strategies utilizing AuNPs.
