The discovery of the so-called Piezo channels earned biologist Ardem Parapoutian the Nobel Prize in Medicine 2021. These molecules are responsible for the perception of mechanical stimuli, but how exactly? The Touch on a Chip (ToaC) project aims at finding this out. ToaC will investigate the expression and distribution of these proteins through a chip that will help recreating physiological conditions. The project is funded by the Italian Ministry for Research and University as one of the Project of Relevant National Interest (PRIN) with a contribution of 640,000€ and will last three years. ToaC is coordinated by SISSA, where it was launched last week, in partnership with two Institutes of the National Research Council, the Institute Officina dei Materiali (CNR-IOM) in Trieste and the Institute Nanoscience (CNR-NANO) in Pisa, and the University of Firenze.
