Novel Porous Silicon Microfabrication Technique Increases Sensing Ability

Georgia Institute of Technology researchers Ali Adibi, ECE, and Ken Sandhage, MSE, have developed a novel method for improving silicon-based sensors used to detect biochemicals and other molecules in liquids. The simplified approach produces micro-scale optical detection devices that cost less to make than other designs, and provide a six-fold increase in sensitivity to target molecules.
