Nanoelectronic devices and sensors

Nanoelectronic devices for quantum computing

The research has been focused on the development of single-electron transistors (SET) for miniaturized electronic systems with a very low energy consumption. Current activities are oriented towards the development of technologies for semiconductor-based quantum computing, within the national project Q-TECH and the Horizon Europe Qu-Pilot Framework Partnership Agreement.

Nanoelectronic devices for (bio)sensing

 The activities in this field have covered a broad range of topics, based on devices such as ion-sensitive field-effect transistors (ISFET) and arrays of metallic micro/nano-electrodes. The ISFET activities included the development of a fabrication method for ISFETs in unmodified CMOS processes of commercial foundries [1], which paved the way for the development of all-electrical next-generation DNA sequencing chips and systems.

The applications have been mainly focused on the biomedical field. Specific examples are microprobe multisensors for cardiac monitoring, olfactory nanobiosensor devices, and point-of-care biosensors for diagnosis and therapy monitoring of heart failure patients.
