TL;DR: A mechanism for creating patterns of iridescent structural colour by total internal reflection of light beams along a concave optical interface leading to interference is described, for complex microscopic systems and for systems as simple as condensed water drops.

TL;DR: This work employs bi-phase emulsion droplets fabricated from immiscible hydrocarbon and fluorocarbon liquids to form responsive micro-lenses that can be reconfigured to focus or scatter light, form real or virtual images, and display variable focal lengths.

TL;DR: In this paper, the authors demonstrate liquid compound micro-lenses with dynamically tunable focal lengths, which can be reconfigured to focus or scatter light, form real or virtual images, and display variable focal lengths.

TL;DR: It is demonstrated that dynamically reconfigurable fluorescent double emulsions can function as highly responsive optical sensors for the rapid detection of carbohydrates fructose, glucose, mannose, and mannan, which are involved in many biological and pathogenic phenomena.

TL;DR: Here, a luminescent photonic substrate with a controlled angular emission profile is introduced and its ability to generate high-contrast dark-field images of micrometre-sized living organisms is demonstrated using standard optical microscopy equipment.
