Remote Radio‐Frequency Controlled Nanoliter Chemistry and Chemical Delivery on Substrates

Abstract

A matter of control: Metallic, self-assembled nanoliter containers have been prepared that can be remotely guided in any chosen spatial trajectory by a magnetic field, as well as remotely triggered by radio-frequency electromagnetic fields to release chemical reactants (see picture). The containers were utilized to facilitate, on demand, spatially localized microfabrication in a capillary and non-invasive chemical delivery to living cells.
