Abstract
A sensor having a substrate is provided in which structures are disposed on a surface of the substrate. The structures can be, e.g., nanostructures. Polarized light is directed toward the sensor, and birefringence of the structures with respect to the light is measured. Target particles that interact with the structures are detected based on changes in the measured birefringence.
