Abstract:
Percutaneous drug delivery refers to the drug coating or application on the skin surface of a drug delivery method. In order to make more drugs transdermal, some pharmaceutical, chemical and physical means are used to promote drug transdermal absorption. The most common method is to use various types of transdermal absorption promoters or substances with good transdermal ability as drug carriers. Dr. Xu is working on transdermal drug delivery techniques based on microneedles and nanoparticles. Through the development of new materials, his team designed microacupuncture skin patches with unique functions to help treat and detect medical problems in skin, cancer, ophthalmology and dentistry. One of the most representative work is the treatment and detection of abnormal scars. In addition, based on the latest nucleic acid nanotechnology, Dr. Xu's team has developed a drug delivery system capable of transdermal anticancer.
Biography：
Dr. Xu obtained his B.Sc. degree in Department of Intensive Instruction of Nanjing University (2002). From 2002 to 2004, he studied at HKUST under the direction of Prof. Bing Xu (Brandeis University) about the synthesis and functionalization of magnetic nanoparticles for protein separation. From 2004 to 2005, he was a visiting scholar in the molecular imaging program at Stanford with Prof. Jianghong Rao, designing self-illuminating quantum dots for cancer imaging. From 2005 to 2009, he did his PhD at Prof. Shouheng Sun’s group of Brown University, focusing on the synthesis of novel platforms of magnetic nanoparticles for biomedical applications including drug delivery and molecular imaging. From 2009-2012, he did his postdoc with Prof. Jeffrey M. Karp at HST in the field of stem cell engineering and drug delivery. He is currently an assistant professor at School of Chemical and Biomedical Engineering, Nanyang Technology University, Singapore. His research interest is the transdermal applications of micro/nano-technologies such as microneedles and nanoparticles.
