Revolutionary Biosensor Chip Performs Multiple Medical Tests with Unprecedented Range.

Scientists have developed a laser biosensor that can perform multiple medical tests simultaneously, including identifying viruses, DNA, and protein markers for certain cancers in a blood sample. The device can detect airborne chemical warfare agents at levels far below toxicity and can identify particles by shining a laser beam on them and measuring the response with a light-sensitive detector. The team's platform can be used for multiple targets and identifies particles by integrating optics and microfluidic channels on a silicon or plastic chip. The researchers are working to adapt their methods to study molecular products from artificial neuronal cell tissue organoids, which could provide further insight into neurodegenerative diseases such as Alzheimer's and pediatric cancers.
