Nanorobot hand made of DNA grabs viruses for diagnostics and blocks cell entry
https://www.sciencedaily.com/releases/2024/11/241127165721.htm
Summary:
A tiny, four-fingered 'hand' folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection
and can even block viral particles from entering cells to infect them,
researchers report.
Dubbed the NanoGripper, the nanorobotic hand also could be programmed to interact with other viruses or to recognize cell surface markers for targeted drug delivery,
such as for cancer treatment.
Could maybe used in an anti-COVID nasal spray,
and be modified for many other viruses.
