Submission + - Biochip could detect multiple viruses, cancers, or toxins in minutes (science.org)
sciencehabit writes: Rapid COVID-19 tests gave many people a firsthand appreciation for the value of quick and cheap diagnostics. Now, researchers have shown how to conduct thousands of rapid molecular screenings simultaneously, using light to identify target molecules snared on top of an array of tiny silicon blocks. In theory, the tool could be used to spot 160,000 different molecules in a single square centimeter of space. Developed to spot gene fragments from the SARS-CoV-2 virus and other infectious organisms, the technology should also be able to identify protein markers of cancer and small molecules flagging toxic threats in the environment.
