The pronounced light-matter interactions in photonic crystals make theminteresting as opto-fludic "building blocks" for lab-on-a-chip applications. Weshow how conducting electrolytes cause dissipation and smearing of thedensity-of-states, thus altering decay dynamics of excited bio-moleculesdissolved in the electrolyte. Likewise, we find spatial damping of propagatingmodes, of the order dB/cm, for naturally occurring electrolytes such asdrinking water or physiological salt water.Comment: 9 pages including 2 figure
