Label-free sensing

Label-free sensing is a technique used to detect and measure molecules or biological substances directly, without adding any dyes, tags, or markers. It relies on detecting inherent properties such as changes in electrical signals, light reflection, or physical characteristics when the target substance interacts with a sensor surface. This approach allows for real-time, accurate analysis of samples in their natural state, simplifying procedures, reducing costs, and minimizing potential interference from additional labels. It's widely used in medical diagnostics, environmental monitoring, and drug development for its efficiency and ability to analyze multiple samples quickly.
