This research is motivated by the fact that even though in today's world remote controlled or wireless devices are part of our daily life, and despite the great strides made in polymeric and micromachined chemical release systems, at the present time there is no microdevice that is capable of releasing chemicals by remote radio frequency (RF) activation. A remote controlled chemical release device would enable on-demand release of chemicals in microfluidic systems and drug delivery in-vivo.

This talk will describe and encapsulation and remote controlled release of dyes and chemicals from 3D pico-nanoliter scale containers. By engineering the porosity of the containers we can control the release profiles of chemicals from the containers to facilitate on-demand spatially controlled chemical reactions. The chemical reactions are monitored by optical microscopy and the reaction products formed.
