Chinese scientists invented a new weapon of the detection of bacteria
Science Times News (Reporter Wang Danhong): Chinese scientists, Chemistry, University of Florida and bio-nano center of Professor Tan Weihong and colleagues have developed one kind of biological nano-particles, and be able quickly to detect a latent in the ground beef a single E. coli, also able for biological terrorist attacks the bacteria issue vital early warning, or for the early diagnosis of the disease. Their findings are published in the October 19 issue of the U.S. "Proceedings of the National Academy of Sciences, they detected E. coli tunnel scanning microscope picture became the cover of this issue," Proceedings of the National Academy of Sciences.
Tan Wei Hong said: "We are committed to the development of a bio-nanotechnology, which combines the technologies of nanotechnology and biochemistry to create a new type of bio-nano-materials, the extraordinary nature of this material allows us to detect a single bacterium within 20 minutes . "
Tan Wei Wang and other newly synthesized compounds called "bio-synthetic nanoparticles. They will track certain bacterial antibody linked to the tiny particles containing dye, this biosynthesis particles containing antibodies to identify specific bacteria. Researchers into many fluorescent dye molecules in which particles, once the particle is found that the bacteria will produce a strong optical signal.
Fast and sensitive analysis is extremely important not only for the early detection of disease, but also of major importance in the battle against bioterrorism. The traditional way to analyze a possible bioterrorism agents take a few days, and request to block the entire region during this time. However, applications Tan Wei Wang's research team of the new method requires only 20 minutes. Chad Mirkin, professor of chemistry at Northwestern University, director of the Northwest Institute of Nanotechnology, he believes this new technology promising, he said: "This is an impressive bacterial detection method, it will be food security impact. "
Tan Wei Wang's research team is currently being developed can detect a variety of bacterial biosynthesis of nanoparticles, these bacteria, including Salmonella, Bacillus cereus spores, as well as food in many toxic substances. Tan Wei Hong said, this ultra-sensitive particles can also be used for detection by terrorists as a weapon of bacteria, the ultra-sensitive analysis of environmental samples and the early diagnosis of disease. He believes that this new technology is the true integration of biological science and nanotechnology.
Tan Wei Wang won the bachelor's degree in Hunan Normal University, Department of Chemistry, Chinese Academy of Sciences, a master's degree and the University of Michigan physics doctorate in chemistry. Has taught at Hunan University, Hunan University Professor Wang Kemin to carried out the research work of the nano-and single-molecule level of bio-analytical chemistry, molecular design and biomedical engineering.
