Drug Delivery Using Nanoparticles

Researchers believe that the potential benefits of nanotechnology will be to provide vast improvements in drug delivery and drug targeting techniques. These new strategies are often called drug delivery systems (DDS). The goal of a drug delivery system is to deliver the medications to a specific part of the body and to control the time-release rate of the

Lab-on-a-chip. Samir Iqbal, a doctoral student in the School of Electrical and Computer Engineering, works under a laboratory hood to transfer a small amount of DNA solution to electronic chips. DNA attaches to gold molecules on such "biochips" in a technology that offers promise for creating devices for detecting bacteria and other substances by combining proteins, DNA, and other biological molecules with electronic components. Such chips might be used to detect cancer cells and cancer-related proteins. (Courtesy Purdue News Service photo/David Umberger)

medication. The drug delivery systems will minimize drug degradation and loss and prevent harmful side effects by delivering therapeutic drugs to the desired site of the body. Drug delivery systems will have potential for many applications, including antitumor therapy, gene therapy, AIDS therapy, and the delivery of antibiotics and vaccines.
