University of British Columbia researchers have invented a silicone chip that could make genetic analysis far more sensitive, rapid, and cost-effective by allowing individual cells to fall into place like balls in a pinball machine.
Sildenafil citrate, commonly known as Viagra, is currently the first choice drug for erectile dysfunction but despite its success oral delivery of the drug is hampered by numerous side effects, the long delay before it starts working and the short amount of time it lasts. Researchers in Egypt think they may have a solution via nanotechnology.
Penn researchers have helped develop a nanotechnology device that combines carbon nanotubes with olfactory receptor proteins, the cell components in the nose that detect odors.
Scientists seeking to improve cancer treatments have created a tiny drug transporter that maximizes its ability to silence damaging genes by finding the equivalent of an expressway into a target cell.
Researchers who have been working for nearly a decade to piece together the process by which an enzyme repairs sun-damaged DNA have finally witnessed the entire process in full detail in the laboratory.
Storing quantum information correctly and permanently has not been possible thus far. The latest studies show that topological memory harbours great potential in this respect – but only if the interferences that eventuate stay put instead of spreading.
A selection of articles on recent advances in polymer solar cell research.
AFS delivers nanometer SPICE accuracy 5x-10x faster for analog and mixed-signal circuits.
Taking advantage of the unique properties of zinc oxide nanowires, researchers have demonstrated a new type of piezoelectric resistive switching device in which the write-read access of memory cells is controlled by electromechanical modulation. Operating on flexible substrates, arrays of these devices could provide a new way to interface the mechanical actions of the biological world to conventional electronic circuitry.
Working in collaboration with the RhineMain Polytechnic, materials scientists at the TU Darmstadt have developed an extremely sensitive explosives sensor that is capable of detecting even slight traces of the high-explosive chemical compound pentaerythritol tetranitrate (PETN). Terrorists had employed PETN in several attacks on commercial aircraft.
