Scientists study new generation of nano-intelligent antibiotics to replace traditional antimicrobials

Professor Wenyuan Shi, director of the Department of Oralbiology at the
University of California, Los Angeles, said in Hangzhou on the 18th that the research on the application of nanotechnology to antibiotic drugs is currently under active development and has achieved phased resultsThe study aims to address the resistance and side effects of traditional broad-spectrum antimicrobial drugs when they act on the human bodyProfessor Shi said there are many types of bacteria in the human body, such asoralcontain more than 700 kinds of bacteria, gastrointestinal more than 1000 kinds, but the vast majority of the human body is beneficialStudies have shown that there are probably no more than 40 pathogenic bacteria in the human bodyAt present, the wide-spectrum anti-biotics widely used in medicine, although strong, but the killing of a wide range of bacteria, and therefore will cause people's physical discomfort of various side effectsMany bacteria have developed resistance due to the widespread use of antibioticsNanotechnology is expected to label antibiotics "smart" and become a "navigator" for antibiotics"This technique can be called targeted sterilization technology, it can target only kill bad bacteria, retain good bacteria, " Shi said, using nano-navigation technology to improve the accuracy of sterilization, greatly reducing the side effects of antibioticsIf this technique is widely used, it will effectively avoid resistance and side effects of broad-spectrum antimicrobials in general and will most likely replace traditional broad-spectrum antimicrobials in the futureAt present, nano-antibiotics in the oral,skin and other easy to touch the effect of fasterProfessor Shi is currently working with Colgate in the United States develop a new generation of mouthwash using nano-intelligent antibiotics to effectively kill dental bacteria Now , the product has entered the second phase of clinical trials , is expected to be available soon (
