Abstract: Systems and methods for molecular sensing are described. Molecular sensors are described which are based on field-effect or bipolar junction transistors. These transistors have a nanopillar with a functionalized layer contacted to either the base or the gate electrode. The functional layer can bind molecules, which causes an electrical signal in the sensor.

Abstract: A non-transitory computer-readable storage medium storing executable instructions to cause a system to detect a genetic variation in a polynucleotide analyte in a sample. A fluorophore is attached to a first primer, a quencher is attached to a second primer, and the first primer and the second primer are specific for the polynucleotide analyte. The primers are configured to amplify the polynucleotide analyte having the genetic variation and a corresponding polynucleotide analyte lacking the generic variation. There is a detectable difference between a measured change in signal generated by the fluorophore and quencher, when using the first and second primers to amplify the polynucleotide analyte with the genetic variation, and a change in signal generated by the fluorophore and quencher, when using the first and second primers to amplify the corresponding polynucleotide analyte lacking the genetic variation.
