The apricots on display in the supermarket look fresh when they have just arrived, but some will have developed bruises by the next day. Hyperspectral imaging allows these fruit to be identified in advance, but is expensive. Now there is a cheaper version of the technique. Peaches, apricots ...
Material could lead to fast, inexpensive sensors
23-10-2007
MIT researchers have created a new structured gel that can rapidly change color in response to a variety of stimuli, including temperature, pressure, salt concentration and humidity. Among other applications, the structured gel could be used as a fast and inexpensive chemical sensor, says ...

Tiny vibrating silicon resonators are of intense interest in nanotechnology circles for their potential ability to detect bacteria, viruses, DNA and other biological molecules. Cornell researchers have demonstrated a new way to make these resonators vibrate "in the plane" - that is, side to ...
Water droplets as templates: gold nanorods self-assemble into rings
14-03-2007
Rod-shaped nanocrystals normally arrange themselves parallel to each other. Researchers at Rice University in Houston, Texas now report in the journal Angewandte Chemie completely unexpected behavior of nano-objects: the spontaneous self-assembly of polymer-coated metallic nanorods into ...
