Review Article on Applications and Classification of Gold Nanoparticles

Abstract

The Nanoparticles have several industrial and biomedical based applications in the diagnosis of different disease, drug delivery and targeted chemotherapy. The major character of nanoparticle is multifunctionality and micro-size. Nanoparticles can be linked with different ligands, therapeutic agents, imaging labels, and other functionalities.  In the review paper we are deliberating the application, types and characteristics of gold nanoparticles which are commonly considered among all the metallo-nanoparticles. Many anticancer medications are present but this causes the necrosis of cancerous cell and as compared the gold nanoparticles cause necrosis of the cancer cells. These are the selected drug delivery schemes which are lesser than the human cells so it can easily enter into the tumors and terminate the cancerous cell. Several anticancer based drugs interconnected with gold nanoparticles and it increased the efficiency of the various anticancer drugs. Gold nanoparticles are valuable for the chemotherapy and also in the diagnosis of cancer due to having high photo and optical property. It is also possible to functionalize with peptides, protein and many nucleic acid units. So the gold NPs have application in bio sensing, gene, protein and drug delivery.
