From: Shaping micro-clusters via inverse jamming and topographic close-packing of microbombs
Experimental procedures for the topographic confinement of microbombs. The corresponding optical images are presented underneath. a Introduction of the microbomb solution on top of the predefined microwells. b Water evaporation and receding meniscus processes to guide the microbomb assembly within the microwells. c Anchored microbombs within the microwell array. Optical images illustrate various possible packing combinations of the number of seeds and the shapes of wells. d Formation of micro-clusters as a result of dense packing and monolithic jamming of the expanded microbombs in confinement. e Release of the clusters utilizing a piece of dissolvable tape
