Photoelectric sensor for detection of kinase activity on the basis of local area surface plasma resonance

The present invention discloses a photoelectric sensor for detection of kinase activity on the basis of local area surface plasma resonance. The biosensor is prepared as follows: a semiconductor material metal oxide is modified onto an indium tin oxide electrode (ITO), then Kemptide, PKA, and a probe are assembled onto the electrode layer by layer, since the probe contains noble metal nanoparticles and photosensitizer tris (bipyridine) ruthenium, under visible light irradiation, the photosensitizer tris (bipyridine) ruthenium captures more photons, local area surface plasma resonance effect of the noble metal nanoparticles occurs under photon excitation, so that more electrons jump onto a semiconductor metal oxide conduction band to produce photocurrent. The biosensor quantitative detection is based on that different concentrations of PKA cause different extents of phosphorylation of Kemptide, so that the amount of the probe connected to the modified electrode is also different, and photocurrent changes are caused. The method has high sensitivity and selectivity, enzyme inhibition experiments also show that the method achieves the purpose of efficient and sensitive detection of the kinase PKA activity.
