Nanogap Sensor Array Wafer Chip Detecting DNA Rapidly and Cost-Effectively

Published on February 24, 2010 at 11:00 PM

IBN has successfully developed a novel electronic sensor array for more rapid, accurate and cost-efficient testing of DNA for disease diagnosis and biological research. This study by IBN Group Leader Dr Zhiqiang Gao and his team was published in the leading international chemistry journal, Journal of the American Chemical Society.

Called the “Nanogap Sensor Array”, IBN’s new device has a unique, vertically aligned nanostructure design and a two-surface configuration based on electronic transduction. The sensor comes with a pair of micron-sized metal electrodes separated by a nanogap (5–20 nm). The biosensor will translate the presence of DNA into an electrical signal for computer analysis.

“By saving time and lowering expenses, our Nanogap Sensor Array offers a scalable and viable alternative for DNA testing.
