Biology and nanotechnology are moving ever closer together. Swiss researchers have developed nanoparticles that can detect, and one day could fight, viruses.
One option for combating viral infections is to develop “artificial” antibodies. These antibodies can have two uses: they can be used to detect infections and, if produced at large enough scale, they can be used to combat infections. That’s what researchers have been working on. Their solution is relatively simple. Find the virus that causes infection; imprint copies of it on a nanoparticle; then use this “mold” to trap the virus.
