The defect-free photonic crystal (PC) slab geometry was explored for size-selective detection of bio-organism simulants. Through feedback between finite-difference time-domain simulations and experiments, we generated a conservative limit of detection estimate for randomized pore filling of a two-dimensional PC slab, and predict that random binding affords the label-free PC-based optical detection of low numbers (of the order of 10) of biological particles.
