Patent ID: 8920718

Claim:
An electrochemiluminescent analytical device to determine an amount of an analyte, said device comprising electrode chip and a hot electrochemiluminescense instrument (HECL), wherein: a working electrode serving as a cathode and a counter electrode serving as an anode are integrated on the chip, and the anode and cathode are connected to the HECL via pads providing an electronic contact; the anode and cathode are constructed on same substrate, said substrate providing a basis of an electrode chip and said substrate being made of an insulating material or partially of conducting and partially of insulating material; the anode and the cathode being made from aluminum or silicon, and the anode successively comprising an insulating film of a thickness of at least 100 nm and coated with an oxide layer of 0.5-50 nm and a carbon paste or silver ink layer, and the cathode being successively coated with an oxide layer 0.5-20 nm and an insulating organic film of 0.5 to 20 nm; wherein during or after applying cathodic or bipolar pulses to the device from the HECL instrument a luminescence signal can be read from the device during, said signal being proportional to the amount of the analyte.
