Researchers designed a completely new treatment for COVID-19, by making a trap made out of nanoparticles to capture viruses. These "Nanotraps" attract the virus by mimicking the target cells that the virus infects. These nanoparticles have a very high density of ACE2 proteins on their surface, which is the main target of the virus spike protein. When the virus binds to the Nanotraps, the traps sequester the virus from other cells, which then allows the body's own immune system to destroy it. When the Nanotraps were tested against the virus and human lung cells, it was found that the virus was completely blocked from entering into the cells. The nanoparticles are only 500 nanometers in diameter and are made of FDA-approved polymers and phospholipids and were found to have no toxicity in mice. In theory, these Nanotraps could also be used on different variants of the virus. Though the therapy remains in the early stages of testing, the researchers envision it could be administered via a nasal spray to treat COVID-19.
