Flexible Biosensor Can Detect More Biotargets

Apr-04-15 A new paper-based diagnostic device able to detect bacteria as well as pathogens could open the tests up for a much wider range of uses.

The research team from Harvard, Stanford and Florida Atlantic created three different thin, lightweight sensors made up of cellulose paper and a flexible polyester film. By using antibodies and peptides to embed the sensors with different electrical and optical sensing modalities, the researchers were able to fine-tune the devices to recognize an array of diseases.

The sensors are inexpensive, easy to manufacture and can be disposed of safely by burning, making them attractive for use in remote and rural areas.
