Researchers at the University of Illinois Urbana-Champaign have developed a tiny, four-fingered “hand” made from a single strand of DNA that can capture the virus responsible for COVID-19, allowing for highly sensitive fast detection, and it can also prevent viral particles from entering and infecting cells. Known as the NanoGripper, this nanoscale robotic hand could potentially be programmed to interact with other viruses or to identify cell surface markers for targeted drug delivery, including treatments for cancer.
