Lopez Smith, a specialist in nuclear magnetic resonance spectroscopy, explains that if the Spike proteins are the keys, the ACE2 peptides would be the locks. “These peptides are compatible with the molecules. So, to neutralize the protein, the chitosan would have to act with peptides to cover the virus,” the scientist details. While this drug sounds like an ideal solution, Dr. López is careful to highlight that this is just a hypothesis. Although it is based on precedents of similar mechanisms, the aforementioned combination has never been applied.
