Abstract
Optical sensors and methods are disclosed. The resonance energy transfer between a donor and acceptor pair on a surface is monitored. The change in resonance energy transfer as a function of the change in refractive index of a sensing area disposed between the donor and acceptor pair is utilized to provide various sensing methods and structures.
