Manufacture Biological Sensors Using Silk and Looms
Posted on January 18, 2015 Comments (2)
The fabric chip platform from Achira Labs in India uses looms to manufacture biological sensors.
Yarn coated with appropriate biological reagents like antibodies or enzymes is woven into a piece of fabric at the desired location. Strips of fabric are then cut out, packaged and can form the substrate for di erent biological assays. Even a simple handloom could produce thousands of these sensors at very low cost.
The resulting fabrics can be used to test for pregnancy, diabetes, chronic diseases, etc.. Achira Labs, an Indian start-up, received $100,000 in Canadian funding in 2013 to develop a silk strip that can diagnose rotavirus, a common cause of diarrhea and can be used in diapers.
The company is planing to start selling silk diabetes test strips using there process this year and expects costs to be about 1/3 of the existing test strips using conventional manufacturing processes.
