A new HIV test the size of a credit card promises to diagnose the disease in minutes rather than weeks, and could be deployed in sub-Saharan Africa as early as next year. In tests, it has detected the amount of CD4 cells in the blood in as little as 10 minutes. The CD4 count indicates …
Recent advances in nanotech devices, point to new ways for developing inexpensive and effective cancer-screening devices. One of the most promising of these new detectors is being built by Charles Lieber, a chemist at Harvard University. In an article this month in Nature Biotechnology, he announced a highly-sensitive detector that can simultaneously find multiple cancer …
Membranes composed of manmade carbon nanotubes permit a fluid flow nearly 10,000 to 100,000 times faster than conventional fluid flow theory would predict because of the nanotubes’ nearly friction-free surface, researchers at the University of Kentucky report in the Nov. 3 issue of Nature. In their study, Mainak Majumder, Nitin Chopra and Bruce J. Hinds …
What are called nanosaws, nanocombs and nanowires can be grown (self-assembled) from cadmium selenium. A study of the temperature and pressure conditions were systematically varied and the impact on the growth was determined. The nanosaws and combs seem to be 2 microns wide. I think the nanowires are a few nanometers thick. While this is …
