Nanosomes the new weapon against coronavirus



A new weapon in the fight against the Covid-19 pandemic may in the future be nanoparticles or nanoparticles, which can be mass-produced cheaper than monoclonal antibodies, and which bind tightly to the protruding SARS coronavirus protein. CoV-2, thus neutralizing its ability to infect human cells. Two new scientific studies, published in the journal Science, present two very different types of promising nanosomes. The best known to date are monoclonal antibodies, which also bind to the coronavirus’s protein, but must be produced in mammalian cells and then administered intravenously. In contrast, much smaller nanosomes, which are more stable and more effective in can be produced more massively and easily into bacteria or fungi through biotechnology techniques and then even administered orally through an aerosol. A research team led by Michael Suff of the University of California and Howard Medical Institute Hughes in San Francisco, presented synthetic nanosomes produced with the help of fungi. The second team, led by Yufei Xiang of the Department of Cell Biology at the University of Pittsburgh Medical School, announced the creation of biological (non-synthetic) nanosomes, which are first isolated from the lama animal and then mass-produced rapidly with the help of microbes. Both types of nanosomes, as experiments have shown, can effectively inactivate the coronavirus. The researchers stressed that “nanoparticle technology can help stop the current pandemic or a future one.”
