Paper-based nanoparticle test kit detects dengue antibodies from saliva

Finding out whether you have been infected with dengue may soon be as easy as spitting into a rapid test kit. The paper-based disposable device will allow dengue-specific antibodies to be detected easily from saliva within 20 minutes. This device is currently undergoing further development for commercialization.

Joint international research project leads to a breakthrough in terahertz spectroscopy

Although terahertz spectroscopy has great potential, especially for environmental monitoring and security screening applications, it previously could not be used effectively to study nanocrystals or molecules at extremely low concentrations. An international team has found a solution to this problem by increasing the technique's sensitivity using metallic nanostructures.

Researchers use sound to slow down, speed up, and block light

Researchers have experimentally demonstrated, for the first time, the phenomenon of Brillouin Scattering Induced Transparency (BSIT), which can be used to slow down, speed up, and block light in an optical waveguide. The BSIT phenomenon permits light to travel in the forward direction while light traveling in the backward direction is strongly absorbed.

Nanoscale lubrication of ionic surfaces

Friction impacts motion, hence the need to control friction forces. Currently, this is accomplished by mechanistic means or lubrication, but experiments conducted by researchers at Oak Ridge National Laboratory have uncovered a way of controlling friction on ionic surfaces at the nanoscale using electrical stimulation and ambient water vapor.
