Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents
Advanced Functional Materials, EarlyView.A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...
