Abstract

We develop numerical modeling techniques to investigate the electrical performance of a deoxyribonucleic acid (DNA) microsensor that uses a carbon nanotube thin film transistor (CN-TFT), and obtain agreement with experiment. This DNA microassay is developed to electrically sense low concentrations (pico to nano Molars) of specific DNA strands without requiring the use of labels such as fluorescent markers.
