Electrically Modulated Drug Delivery using Nanoporous Electrodes
Published online by Cambridge University Press: 31 January 2011
Abstract
Nanoporous electrodes, such as those made from carbon or gold, can capture and release ionic analytes at concentrations near 1 mole per liter of pore volume through capacitive charging or electrochemically reversible adsorption. In vitro studies suggest that this phenomenon can be the basis for a noninvasive, precise, and programmable drug delivery method. It would eliminate the need for bulk fluid delivery to target tissue and require only a thin electrical connection, minimizing pain and tissue disruption. We have designed effective gold electrode assemblies and observed the depletion and release phenomena using electrochemical methods and charged dyes.
