Wireless control of chemistry and chemical delivery was achieved using metallic, self-assembled nanoliter containers that were both remotely guided in any chosen spatial trajectories, as well as remotely triggered to release chemical reactants. Remote guidance was enabled using magnetic fields, and remote release of chemicals from specific containers was triggered using radio frequency (RF) electromagnetic fields. The nanoliter containers were utilized to facilitate on-demand, spatially localized chemistry on substrates, reconfigurable microfluidic systems and non-invasive chemical delivery to living cells.
