Detecting Molecules with Light

Optical biosensors detect target molecules with light. They monitor binding by reading an optical signal from the sample. This makes them useful for seeing when a target molecule is present.

Some optical biosensors use a label molecule. The label creates a measurable signal, such as fluorescence....

Optical biosensors are sensors that detect a biological target or targets of interest using light. These devices have found applications in healthcare, pharmaceuticals, environmental monitoring, Homeland Security, and even the battlefield. Optical biosensors are broadly divided into label-based and label-free sensors. An example of label-based s...
