A biosensor has been proven capable of detecting molecules associated with neurodegenerative diseases and some types of cancer. The device is a single-layer organic nanometer-scale transistor on a glass slide. It contains the reduced form of the peptide glutathione, which reacts in a specific way when it comes into contact with the enzyme glutathione S-transferase, linked to Parkinson’s, Alzheimer’s and breast cancer, among other diseases.
