สล็อต The plague made a mask. And various types of personal protective equipment are increasingly needed to prevent the spread of COVID-19.In the latest research The scientists found that researchers may have developed a self-healing biosynthetic polymer material from protein synthesis found in squid's teeth.A study recently published in the journal Nature Materials indicates that an international team of researchers from Germany, Turkey and Penn State University in the US has described how they can transform the characteristic protein found in squid teeth into. Soft and biodegradable material. This could be used in the development of "soft robots" or soft robots. And personal protective equipment that is tear resistantSelf-repairable materials are not new. But researchers say the materials available today can take up to 24 hours to repair itself. And those materials are often not as strong as the original.
