Abstract

Disclosed are sensors that include a carbon nanotube channel and a non-fouling polymer layer, where the non-fouling polymer layer and the carbon nanotube channel do not directly contact each other and are separated by a dielectric layer. The disclosed sensors may be used, e.g., as biosensors for the accurate and sensitive detection of analytes within a sample. Also disclosed are methods of making and using the sensors.
