label-free biosensing

Label-free biosensing is a method used to detect biological molecules directly without needing extra markers or dyes. It works by measuring how these molecules interact with a sensor’s surface—such as changes in electrical signals, light, or physical properties—when they bind to it. This approach allows scientists to observe real-time interactions, providing valuable information about the presence, amount, and behavior of specific molecules. Label-free biosensing is useful in medical diagnostics, drug development, and environmental monitoring because it simplifies testing processes and offers quick, accurate results without additional labeling steps.
