Understanding Quartz Crystal Microbalance Biosensors
A quartz crystal microbalance biosensor utilizes a piezoelectric crystal to detect mass changes at a molecular level. When a biomolecule binds to the surface of the crystal, it causes a shift in frequency that can be accurately measured. This unique characteristic allows researchers to monitor interactions between biomolecules in real-time, making QCM biosensors invaluable in various applications.
Principles of Operation
The fundamental working principle of a quartz crystal microbalance biosensor revolves around the piezoelectric effect. When an electrical signal is applied, the quartz crystal oscillates at a specific frequency. If a substance adheres to its surface, the change in frequency correlates with the mass of the attached molecules. This highly sensitive measurement enables precise detection of biomolecular interactions.
