Screen printed mu-electrodes for photochemicail applications

A new device, based on screen printed electrodes, was realised allowing low manufacturing costs and rapid analyses with PSII or with other biological (algae) or photochemical catalysts. The L-electrode was cut from a PVC sheet, on whose two sides graphite and silver pastes were deposited by screen printing techniques. The biosensor was placed in a flow cell obtained by carving a light emitting diode (LED). Details on the layout of the electrode and the flow-through mu-cell are described together with preliminary results obtained by detecting H2O2, K4Fe(CN) (6), Glucose and PII activity.
