Abstract

We report on a new technique known as Near Field Electroprinting (NFEP) to fabricate a gelatin hydrogel based array for use as an electrochemical sensor. Using this technique, an array of gelatin fibers one micron in diameter and spaced approximately 100 micron apart, was patterned and subsequently cross-linked. To validate its use as a sensor, the ends of the array were coated in gold to provide electrical connections and a CV was performed using a ferricyanide redox couple. This work opens up the development of printed hydrogel biosensors exploiting the biocompatibility of hydrogel materials.
