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.
