Fabric Chip

Manufacturing challenges, costs and environmental concerns associated with plastics have prompted the exploration of naturally wicking substances for performing diagnostic tests. Along with paper, fabric is another medium whose natural wetting properties can be used as the basis of biological assays. Achira is working on developing textile weaving as a platform to manufacture sensors. Our deeply innovative Fabchip platform takes advantage of the existing expertise and capital infrastructure available in the textile industry to manufacture biological sensors. The idea is simple but the output can be complex and flexible.

Schematic of the fabric chip weaving process

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 1000s of these sensors at very low cost. Click here to view our article that was published on the cover of the top micro fluidics journal Lab on a Chip.

The salient features of the platform are:

  • Highly affordable sensors
  • Both yes-no and quantitative results possible
  • Multiplexing is also possible
