Optical Biosensing

Optical biosensors utilize light to detect the binding of a target molecule. These sensors can utilize a label molecule, which produces a measurable signal such as fluorescence,or these sensors can be label-freeand use the changes in optical properties, such as refractive index, to sense for the binding of the target molecul...

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...
