Fully Depleted Exponentially Coupled (FDEC) Field Effect Transistor (FET) nanowire sensors

We have invented an exponential nanosensor technology for chemical and biological sensing applications. This means in our nano sensor devices the detection signal is not diminished like in other sensor technologies, but is internally amplified by our device up to an order of magnitude owing to a unique capacitive coupling we discovered.


This unique nano-scale phenomena results in very high specificity of signal transduction for low false positives and low false negatives. As a result our device is capable of ultra high sensitivity molecular detection coupled with exceptional selectivity. The technology, termed Fully Depleted Exponentially Coupled (FDEC) Field Effect Transistor (FET) nanowire sensors, is superior to other sensor technologies presently available.

We expect our Exponential nanosensor technology to have a disruptive effect in certain niche fields of application, while are prospective of creating new markets in futuristic applications of in vivo implantable devices and in vitro advanced drug discovery applications. Silicon based ULSI nano manufacturing technologies allow us to fabricate ultra compact devices with system-on-chip and lab-on-chip integration, that are also inexpensive compared to other technologies.

We are building a robust intellectual property portfolio (patents awarded & pending) by developing key technologies in-house and in-licensing of complementary technologies from partnering institutions.
