Abstract
The present invention relates to a biochip with a piezoelectric element for ultrasonic standing wave generation. The biochip comprises an upper module, a lower module, and a chemical sensor. The piezoelectric element is integrated within the upper module of the biochip. The piezoelectric element can generate ultrasonic standing waves (USW) in the reaction chamber of the biochip by manipulating the operation frequency so the particles being detected can effectively move toward the QCM sensing surface. Hence, the biochip significantly increases the sensitivity and reduces the time required to reach equilibrium when undergoing USW excitation. The biochip of the present invention can be broadly applied to the bio-detection in medical and pharmaceutical fields.
