3D-printed Devices

A 3D printing process is used for the fabrication of  electrochemical cell-on-a-chip devices, which are applied to voltammetric sensing of pharmaceuticals, heavy metals and enzymatic biosensing. The  devices are entirely  printed via a single-step process using a dual extruder 3D printer and are composed of vessels/holders/parts (printed from  non-conductive filaments) and of  integrated thermoplastic electrodes (printed from  conductive filaments).
