Abstract

AbstractIn this work, a class of bubble‐containing multicompartmental particles with self‐orienting capability is developed, where a single bubble is enclosed at the top of the super‐segmented architecture. Such bubbles, driven by potential energy minimization, cause the particles to have a bubble‐upward preferred orientation in liquid, enabling efficient decoding of their high‐density signals in an interference‐resistant manner. The particle preparation involves bubble encapsulation via the impact of a multicompartmental droplet on the liquid surface and overall stabilization via rational crosslinking. The conditions for obtaining these particles are systematically investigated. Methodological compatibility with materials is demonstrated by different hydrogel particles. Finally, by encapsulating cargoes of interest, these particles have found broad applications in actuators, multiplexed detection, barcodes, and multicellular systems.
