An example of the detection of acetylcholinesterase (AChE) with the quartz crystal microbalance (QCM) system.

The whole process included the immobilization of glutaraldehyde and AChE antibody, glycine blocking and the detection of AChE. First, the glutaraldehyde was injected into the QCM device to activate the surface of the gold electrode; then the AChE antibody was injected into the device to be immobilized onto the electrode surface via the aldehyde group of the glutaraldehyde. After glycine blocking, samples were added into the QCM device for detection.
