Nanotechnology based drugstore cancer tests

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 …

Faster fluid flow in carbon nanotubes

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 …

Quantum computing: Avenue to room tempurature quantum info processing

Researchers at UC Santa Barbara have potentially opened up a new avenue toward room temperature quantum information processing. By demonstrating the ability to image and control single isolated electron spins in diamond, they unexpectedly discovered a new channel for transferring information to other surrounding spins — an initial step towards spin-based information processing. A team …

Nanoscale technology: Quantum dots produce white light : light bulb replacement

Quantum dots that produce white light could be the light bulb’s successor But chemists at Vanderbilt University discovered a way to make quantum dots spontaneously produce broad-spectrum white light. The report of their discovery, which happened by accident, appears in the communication “White-light Emission from Magic-Sized Cadmium Selenide Nanocrystals” published online October 18 by the …

Quantitative Cell Biology

This will help put us on the path to computational cell biology as an extension of computational chemistry. Computational chemistry is important to the development of molecular manufacturing. Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, …

Better Use Of Nanotubes As Measuring Tips

Advances with atomic force microscope accuracy advance us on the path towards molecular manufacturing. However, this does not achieve 0.5 angstrom accuracy as some Scanning Electron Microscopes have. It does help more labs get greater accuracy. Engineers at Purdue University have shown how researchers might better use tiny hollow fibers called “multi-walled carbon nanotubes” to …
