Description

technical field [0001] The invention relates to the technical field of smart materials, in particular to an electrochemiluminescent hydrogel composite material and its preparation method and application. Background technique [0002] Electrochemiluminescence is a method in which chemiluminescence is excited electrochemically. During this process, molecules or quantum dots with electrochemiluminescence activity are oxidized or reduced on the electrode surface to form an excited state, and luminescence will occur when the excited state returns to the ground state. Electrochemiluminescence analysis has the advantages of high sensitivity, low background signal, and good space-time controllability. It has a wide range of applications in food analysis, drug analysis, biological imaging and analysis. However, the traditional solution-state electrochemiluminescence has some shortcomings, such as complex experimental equipment, easy to cause reagent contamination, and is not conduci...
