Scientists at the University of Vu in Amsterdam, the Republika Srpska Institute and the University of Michigan have discovered the protective armor of the virus. This armor, consisting of simple proteins, begins with a fragile contrast, but then passes through an extraordinarily intensive process. Surprisingly, strengthening the virus is not an end, but in three separate ways. The researchers reported their findings at this week's Proceedings of the National Academy of Sciences.
The team, led by Gijs Wuite, a professor at VU University, used a highly powerful AFM to find viral particles with a size of just dozens of nanometers. In this way, it is not only necessary to detect viruses, but also to test their material properties. By using a tiny needle and pushing it from the surface into the virus, the researcher's 沃特·鲁斯 can accurately differentiate the mechanical resistance. The virus's sophisticated process, in which the DNA virus during the process, the virus surprisingly use three different mechanisms, together to strengthen the protein shell.
This extra protective armor needs to be outside the virus, providing a livelihood protection for many different viruses that are invading their strength. In unraveling this process, researchers now have a clear picture of how a virus can build armor. In order to impact the use of viruses and biomedical and nanotechnology, this study is very serious.
