Washington, Aug 27 - Scientists have come up with a novel electronic sensor that ensures faster, more accurate and cost-effective testing of DNA for diagnostics and biological research.

Developed by the Singapore-based Institute of Bio-engineering and Nanotechnology (IBN), the Nanogap Sensor Array has shown 'excellent' sensitivity in detecting trace amounts of DNA.

'This new bio-sensor holds significant promise to speed up on-going efforts in the detection and diagnosis of debilitating diseases such as cancer, cardiovascular problems and infectious viruses,' Jackie Y. Ying, IBN's executive director, said.

'By saving time and lowering expenses, our newly developed Nanogap Sensor Array offers a scalable and viable alternative for DNA testing,' said Zhiqiang Gao, who led the research at the IBN.
