Researchers from the University of Central Florida in the U.S. have developed a new technique for quickly identifying bacterial infections using sugar-coated gold nanoparticles. The article says: “As more bacterial strains resistant to many drugs emerge, it becomes more critical to quickly identify infections and the antibiotics that would most effectively treat them. Such quick identifications become even more important during epidemics because large numbers of samples would have to be tested at once.” According to researcher Manuel Perez, the technique can also be used by research institutions and pharmaceutical companies to screen drugs for antibacterial activity. The technique uses gold nanoparticles coated with a sugar and a sugar-binding protein. In the presence of different antibiotics, the gold nanoparticles display optical variations that can be read by a spectrophotometer to determine which antibiotics effectively stop bacteria growth and which do not. According to the article, results are rendered within a few hours, as compared to conventional methods which can take several days. The article says that, additionally, the technique can test hundreds of samples at once using small amounts of bacteria and antibiotics and that the method does not require new equipment. The article can be viewed online at the link below.
