UGA Researchers have golden touch
GRA Eminent Scholar Ralph Tripp and colleagues at the University of Georgia have developed an inexpensive, rapid, sensitive diagnostic test for influenza. Until now, physicians and public health officials have had to choose between a highly accurate yet time-consuming test or a rapid but error-prone test.
By coating gold nanoparticles with antibodies that bind to specific strains of the flu virus and then measuring how the particles scatter laser light, the technology can detect influenza in minutes at a cost of only a fraction of a penny per exam.
“We’ve known for a long time that you can use antibodies to capture viruses and that nanoparticles have different traits based on their size,” said study co-author Ralph Tripp, GRA Eminent Scholar in Vaccine Development in the UGA College of Veterinary Medicine. “What we’ve done is combine the two to create a diagnostic test that is rapid and highly sensitive.”
In addition to other viruses that infect humans, the diagnostic strategy may be useful in identifying viral infections that plague poultry, one of Georgia’s leading industries. Read more>
