A) Schematic of the LC director profiles (dotted lines) for spherical LC droplets in the bipolar (left) and radial (right) states. Black points represent characteristic defects associated with each state. B-C and D-E show bright-field (B, D) and polarized-light (C, E) micrographs of 5CB droplets in the bipolar (B-C) and radial (D-E) states. B-C) Images of LC droplets dispersed in PBS. D-E) Images of LC droplets dispersed in PBS after the addition of 3-oxo-C12 AHL (50 μM). Droplets in (C) and (E) were imaged using crossed polarizers oriented parallel to the 30 μm scale bars in the main image (scale bars = 10 μm for insets).
