Label free optical biosensors enable the monitoring of biomolecules and their interactions in often highly sensitive diagnostic assays. Several methods have been employed for this purpose, including Whispering Gallery Mode (WGM) biosensing, which offers a particularly sensitive approach to ...
New photoacoustic technique detects multiple nerve agents simultaneously
16-08-2012
To warn of chemical attacks and help save lives, it's vital to quickly determine if even trace levels of potentially deadly chemicals—such as the nerve gas sarin and other odorless, colorless agents—are present. U.S. Army researchers have developed a new chemical sensor that can ...
