Nanowell field-effect transistor for highly sensitive molecular detection

Towards scalable single-molecule sensing for genomics and proteomics 


Researchers at imec unveil a pioneering bio-molecular sensor device – a nanowell FET, an upgraded version of their earlier FinFET biosensor. 

The device features a 25 nm size nanowell in the center of a 35-40 nm wide silicon FinFET, enhancing molecular detection sensitivity, with near-ideal electrical properties. 

Additionally, binding inside the nanowell may become self-limiting, which could enable single-molecule sensing.
