An internationally renowned academic journal, Nature and Nanotechnology, published a result of Chinese scientists: They made "nano-hepatic" into the body and helped the liver break down alcohol. Professor Ji Cheng, from the Center for Liver Diseases, University of Southern California School of Medicine, is a collaborator of this achievement. He told reporters, "Scientists have clearly broken down the enzymes of alcohol, but they are sent to the human body and remain active and work quickly and efficiently, but it is difficult to do." Lu Yunfeng, a professor at the Department of Chemistry and Molecular Bioengineering at the University of California, Los Angeles, found it. The solution: he uses a non-toxic composite polymer material to make a delicate nano-scale cage that contains enzymes that break down alcohol. With this "protective suit", the enzyme is not afraid of being broken down by the digestive juice, and it can safely break down alcohol molecules. Lu Yunfeng introduced that this small cage should contain the next enzyme stream - the first enzyme will oxidize alcohol molecules into acetaldehyde, and produce a hydrogen peroxide molecule (which will kill cells, harmful to humans), the second enzyme will The hydrogen peroxide molecules are immediately separated and decomposed. "These two enzymes must be close enough to prevent the bad guys from 'escape' the cage and harm the body." Lu Yunfeng said that the enzymes that currently degrade acetaldehyde have not been successfully cloned. The next step for scientists is to The three enzymes were cloned out and loaded into nano-cage - "nano-liver" to be truly completed.
