Femtorays Technologies (FTH) is an innovative SME located in the Trentino region that possesses a patented technique for detecting dispersed molecules in a fluid, based on integrated optoelectronic technology, including a Silicon Photonics chip with a series of miniaturized active sensors, a low-noise electronic circuit for reading the active sensors, and a software for interpreting and modeling the data.

FTH photonic multiplexing sensor system is based on arrays of biosensors controlled by a closed-loop locking of their relevant optical parameters. This was demonstrated to achieve superior sensitivity and response time thus increasing existing systems’ capabilities by several orders of magnitude up to the unprecedented label-free detection of single-molecules.

FTH’s patented technology utilizes a single, external laser source to drive all sensors and local on-chip modulators on each sensor to lock the optical parameter of interest to its initial state. The variation of the feedback signal over time is thus an accurate representation of the optical parameter shift of each sensor that is caused by biosensing.
