Patent ID: 8765056

Claim:
A microfluidic mixing chip having a light emitting compound, comprising: a first side cavity; a second side cavity; and a mixing cavity disposed between the first side cavity and the second side cavity and connected to the first side cavity and the second side cavity through microchannels, the mixing cavity being joined to the microchannels at sharp corners and having the light emitting compound, a redox reagent and a catalyst; wherein a pair of electrodes are disposed to the first side cavity and the second side cavity to provide a power source with only an identical phase of high frequency alternating current electric field to induce electric charges at the surfaces of the sharp corners to generate electro-osmotic flow, and the light emitting compound, the redox reagent and the catalyst are mixed in the mixing cavity by utilizing the power source with high frequency alternating current electric field, thereby producing a chemiluminescence optical signal or a bioluminescence optical signal.
