DNA 'NanoGripper' Hand Offers New Hope for COVID-19 Detection and Treatment

Researchers at the **University of Illinois Urbana-Champaign** have engineered an innovative tool called the **NanoGripper**, a tiny, DNA-based nanorobotic hand capable of both detecting and blocking the virus causing COVID-19. Inspired by the human hand and bird claws, the NanoGripper features **four bendable fingers and a palm** constructed from a single DNA strand. Each finger has **three joints**, allowing it to grip target molecules, such as viral proteins. This groundbreaking device holds promise for rapid virus detection, matching the accuracy of qPCR molecular tests within 30 minutes. Beyond diagnostics, the NanoGripper can prevent infection by blocking viral particles from entering cells. Researchers envision a **nasal spray formulation** of NanoGrippers acting as a preventive measure against respiratory viruses like COVID-19 and influenza. The technology could also extend to targeting other viruses or cancer markers, potentially transforming targeted drug delivery methods.
