A Catalytic Nanomaterial-Based Optical Chemo-Sensor Array.

The article presents a study on a catalytic nanomaterial-based optical chemo-sensor array known as electronic tongues that create sensing elements of the array. The researchers made an observation of Chemiluminescence (CL) generated on the surface of solid materials in the mixture of porous silicon with nitric acid. The study found out that CL luminescent efficiencies are different for a given compound on different nanomaterials.
