ATP-detecting nanosensors could help reduce laboratory animal testing

By - January 10, 2012 2 Pictures
Animal testing is an area that elicits strong feelings on both sides of the argument for and against the practice. Supporters like the British Royal Society argue that virtually every medical breakthrough of the 20th century involved the use of animals in some way, while opponents say that it is not only cruel, but actually impedes medical progress by using misleading animal models. Whatever side of the argument researchers fall on, most would likely use an alternative to animal testing if it existed. And an alternative that reduces the need for animal testing is just what Fraunhofer researchers hope their new sensor nanoparticles will be. Read More

Magnetic nanotags detect cancer much earlier than current methods

By - October 19, 2009 2 Pictures
Extremely sensitive nanosensor chips are being developed by Stanford University researchers in an attempt to detect the early signs of cancer, called biomarkers, in humans. The researchers say their sensor is around 1,000 times more sensitive than current technology and is accurate regardless of which bodily fluid is being analyzed. It can also detect biomarker proteins over a range of concentrations three times broader than any existing method. It is forecast that earlier detection of cancer biomarkers will lead to improved survival rates among cancer sufferers. Read More
