Abstract

Khalid Alaqad and Tawfik A Saleh

Nanoparticles are widely used in the biotechnology and biomedical field. Their large surface area, remarkable physical properties, enhanced permeability, and retention effect make them as promising candidates in biomedical applications such as diagnosis and therapy. The gold and silver nanoparticles proved to be the safest for drug applications. The gold and silver nanoparticles are considered very important and interesting for several applications. This review provides a summary of Au and Ag nanoparticles synthesis, characterization, and applications. The review will focus on the use of nanoparticles in drug delivery and in determining and sensing of drugs in pharmaceuticals.
