Electric Jolt Triggers Release of

This article is about research being done at Johns Hopkins University using bursts of electricity to release particles from a gold electrode. This method could be used to release medicine or nanoparticles into the body. The gold electrodes are as thin as a piece of hair, and are attached to a chain of hydrocarbons with a biomolecule on one end. The current breaks the bond and releassd the biomolecule into the body.
