A novel protein immobilization approach for piezoelectric immunosensors based on the sam of derivative aa has been proposed, which is formed by coupling merca ptoprorionic acid ( mpa ) to alginic acid sodium salt via edc and nhs. ( 1 ) the tr antibody is immobilized via edc and nhs. comparing with the mpa sam method, this new approach shows greater frequency response and high sensitivity
