A paper by researchers at the National Institute of Standards and Technology (NIST) may breathe new life into the use of a powerful"”but tricky"”diagnostic technique for cell biology. The paper,* appearing this week in the Biophysical Journal, demonstrates that with improved hardware and better signal processing, a powerful form of molecular vibration spectroscopy can quickly deliver detailed molecular maps of the contents of cells without damaging them. Earlier studies have...

In two landmark studies published today in the journal Drug Testing and Analysis (DTA), UK and Swiss research teams reveal two techniques proven to identify dissolved cocaine in bottles of wine or rum. These tools will allow customs officials to quickly identify bottles being used to smuggle cocaine, without the need to open or disturb the container. Cocaine is among the most common drugs of abuse and a large number of imaginative techniques of smuggling cocaine through border controls have...

Portable devices that use a laser beam to probe bones, teeth, and other parts of the body for early signs of diseases like osteoporosis and tooth decay may seem like something out of science fiction. But those devices are moving closer to reality, according to an article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine. C&EN Senior Editor Celia Henry Arnaud notes that these new diagnostic tools will have the ability to see beneath the skin and...

A new "on-chip" method for sorting and identifying bacteria has been created by biomedical engineers at Taiwan's National Cheng Kung University. The technique, developed by Hsien-Chang Chang, a professor at the Institute of Biomedical Engineering and the Institute of Nanotechnology and Microsystems Engineering, along with former graduate student I-Fang Cheng and their colleagues, is described in the AIP journal Biomicrofluidics. Using roughened glass slides patterned with gold electrodes, the...

Surface plasmons are quanta of collective oscillations of free electrons at metal-insulator interface, usually excited by photons. Since it was first proposed in 1950s by Ritchie, new interests have been aroused due to recent advances in synthesis and fabrica-tion of various nanostructures. Novel optical properties were frequently reported on these materials, with great potential applica-tions in physics, chemistry, biology and cancer therapy, etc. Some of them have even exhibited enormous...

Microorganisms are everywhere and most of them are harmless, but they can do a lot of damage in the manufacture of pharmaceuticals or in tissue transplants. With the aid of a new device, germs can be detected in artificial cartilage within a few hours. We are surrounded by microorganisms. They inhabit our skin, the air we breathe, the surfaces we touch. In most cases this is not a problem, but there are situations in which these constant companions can be dangerous or even life-threatening....
