Paper-based Biosensors

John Brennan and his research group have discovered an incredibly sensitive and simple way of detecting pesticides in foods - paper-based biosensors. Pesticides in the nanomolar range can be detected within 5 minutes - rivaling the traditional method of detection through mass spectrometry with significantly less expense. This makes testing in remote sites far easier and more likely to occur as a simple colour change would indicate the presence of the chemicals without fancy instrumentation.
