Under the disturbance of BSA molecules, the ordering of LC in microcavity is changed. With the increase of BSA concentrations, the illustrations of the ordering of LC molecules gradually changes towards the planer molecular orientation from top to bottom (left). The right panel shows the corresponding polarized optical images of LC-amplified optofluidic cavity. Scale bar: 100 μm
