What is it about?
Bloch surface wave is a very powerful method to detect proteins at the surface, because you can shape the near field for a wide wavelength range.

Why is it important?
The surface is smooth. If there are no substances in the light field then there is no scattering. This leads to a very high signal to noise ratio.
