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 .
