Indian Institute of Technology Guwahati Researchers have developed a low-cost, hand-held device to detect bacteria. This Research by IIT Guwahati will enable rapid detection of bacteria, which is important not only in healthcare, but also in anti-bioterrorism measures and environmental monitoring applications.
The research team led by Prof Parameswar K Iyer, Department of Chemistry, and Prof Siddhartha S Ghosh, Department of Biosciences and Bioengineering, IIT Guwahati, has developed this novel, low-cost, bio-compatible sensor that can detect bacteria almost instantaneously without the need for cell culture and microbiological assays. The Organic Field Effect Transistor (OFET)-based bacterial diagnostic device has been shown to have the ability to detect 103 cfu mL-1 of bacteria and distinguish between Gram positive and Gram negative types.
Their work has been patented as well as published in the July 2019 issue of the reputed peer-reviewed Journal of Materials Chemistry A of the Royal Society of Chemistry.
