An organic transistor-based system for electrophysiological monitoring of cells is disclosed. The system includes a plurality of organic transistors each comprising: a floating gate electrode; a source electrode and a drain electrode; an organic semiconductor; an insulating layer; and a sensing area. A barrier mechanically separates said sensing area and a transistor area. Each organic transistor includes a control gate electrode coupled to a second portion of said floating gate electrode external to said sensing area by a capacitor. The control gate electrode is separated from said floating gate electrode by said insulating layer. The control gate electrode sets a working point of the organic transistor to which the control gate electrode belongs to by a control voltage (V) applied to it. In each organic transistor, an overlapping area defined by said control gate electrode formed above said floating gate is comprised between 9*10cmand 2*10cm.
