Enzyme coated Carbon Nanotube Sensor
Scanning Electron Micrograph of Enzyme Coated Carbon Nanotube
We developed Enzyme coated Carbon Nanotubes (ECNT) as a miniaturized enzymatic biosensor for medical, environmental and chemical analysis. Carbon Nanotubes have a three dimensional network that provides excellent stability, promotes enhanced enzyme loading and provides increased analyte exposure. Nanotubes are coated uniformly with an enzyme specific to the desired analyte to provide unsurpassed sensitivity and selectivity. An ECNT electronic tongue can analyze a large number of analytes from a single drop of blood, urine or saliva for metabolic analysis. In addition to metabolic sensing, an ECNT electronic nose can perform similar functions for toxic gas detection and chemical warfare sensing.
