| Summary:

The precise control of complex reactions is critical for biological processes
ranging from cell division to metabolism. Synthetic analogues of living
materials suffer from our inability to tune chemical reactions with precise
outcomes. Here, we leverage differentiable simulators to design nontrivial
reaction pathways in colloidal assemblies. By optimizing interactions between
reactants and substrates, we achieve controlled disassembly of octahedral and
icosahedral shells. As a potential engineering target, we design a reaction
that provokes the release of a small particle trapped in a shell.
