Scientists from the University of Georgia developed a new flu test that is fast an accurate. The test first coats gold nanoparticles with antibodies. These bind to certain strains of the flu virus. Then, it measures how the nanoparticles scatter laser light. This allows the test to find influenza quickly.
The scientists came up with this test by knowing that antibodies can capture viruses and that nanoparticles have different traits based on their size. They combined these two to make a test that is sensitive and fast. An engineer in the UGA Nanoscale Science and Engineering Center linked antibodies and immune system proteins with gold nano particles. These bond with any flu virus by measuring the intensity with which light is scattered by the solutio.
This is an inexpensive teset because the amount of gold used per test is just 100th of a cent. These scientists are also working on ways poultry producers can use this type of test to detect salmonella. They don't wanna stop just at influenza because the test offers great advantages.
