GEN’s editor in chief, John Sterling, interviews life science academic and biotech industry leaders on important research, technology, and trends. These podcasts will keep you informed with all the important details you need.

Scientists at Singapore’s Institute of Bioengineering and Nanotechnology say they have developed a novel electronic sensor array for more rapid, accurate, and cost-efficient testing of DNA for disease diagnosis and biological research. In an online paper in the Journal of the American Chemical Society on August 5, the researchers reported that based on laboratory results, their Nanogap Sensor Array has shown excellent sensitivity at detecting trace amounts of DNA.


During this week's podcast Dr. Zhiqiang Gao talks about the new sensor in detail and describes its main advantages for life science research as well as how it differs from other sensors. He explains how the nanogap sensor works in terms of DNA detection and discusses the work his laboratory plans to carry out to advance the capabilities of the new sensor.
Dr. Zhiqiang Gao is the Group Leader of the Biosensors and Biodevices Group at the Institute of Bioengineering and Nanotechnology (IBN), Singapore. He received his B.Sc. and Ph.D. in Chemistry from Wuhan University, China. Dr. Gao pursued his postdoctoral fellowship at the Åbo Akademi University, Finland and The Weizmann Institute of Science, Rehovot, Israel. He spent three years at various institutions in the United States before joining IBN in December 2002. His research interest includes ultrasensitive biosensors for nucleic acids and proteins, synthesis of multifunctional biotags and the design of DNA-targeted agents.
