Alzheimer’s Molecules Can Be Detected by Researcher-Developed Nanoscale Biosensor
Brazilian researchers have developed a nanoscale biosensor that can detect molecules linked to Alzheimer’s, as well as other neurodegenerative diseases, and certain cancers. The system marks a new era where highly sensitive, inexpensive, and portable devices might become accessible by healthcare professionals, and in settings without access to traditional resources. The sensor, created at the National Nanotechnology Laboratory (LNNano) in Brazil, reacts when the enzyme GST encounters a molecule called peptide glutathione, or GSH. This molecular meeting results in a biochemical reaction that can be detected by a transistor the size of a small virus (there are viruses 100 times as big). "Platforms like this one can be deployed to diagnose compl
