The device's nanoscale transistor sensor is 1,000 times faster than current commercial nanopore technologies. The sensor is capable of high detection sensitivity and high sampling frequency that surrounds a central nanopore and allows DNA bases to be read at speeds of up to 1 million bases per second per pore. A FENT chip with 100,000 pores that can read up to 105 bases per second per pore is expected to sequence an entire genome in a few minutes, according to the company.

FENT combines complementary metal oxide semiconductor transistor technology with solid-state nanopores to offer faster DNA sequencing. Prototype FENT transistors with a nanopore diameter of less than 50 nm achieve an operating speed of 100 MHz. Previously, the company developed proprietary processes for making sub 5-nm nanopores in silicon. INanoBio said that it plans to integrate the FENT transistor with the sub 5-nm nanopores and scale the production of FENT array chips.

The goal is to have this targeted sequencing-based bedside diagnostic testing device "in every home" that can accurately detect pathogenic infections in presymptomatic stages to preempt future pandemics.
