The porous and superhydrophobic shell of a liquid marble prevents contact of its liquid core with outside surfaces, but allows gas transport. Liquid marble can therefore be used to sense gas or emit gas. Liquid marbles loaded with different indicators can simultaneously sense different gases via different mechanisms.

Environmental Gas Sensing with Cavitands
Chemistry – A European Journal, 2017AbstractEnvironmental gas sensing needs stringent sensor requirements in terms of sensitivity, selectivity and ruggedness. One of the major issues to be addressed is combining in a single device the conflicting requirements of molecular‐level selectivity and low‐ppb sensitivity.
