A new nano device has been developed by a research team at Harvard Medical School led by Ralph Weissleder. The nano device is able to detect as little as 20 bacteria in 30 minutes.
The biggest problem with current tests is how slow they are at diagnosis. The current benchmark test is a skin test that detect immune reactions. This nanodevice test can increase the diagnosis rate. It could be cheaply developed and used around the world as a fast test for TB. The current skin test apart from being relatively slow is known to be unreliable too.
This new quick test would make diagnosis far more reliable and faster at what is hoped to be a much cheaper price per test allowing low income countries to test with this technology. – CT
