Abstract

High-resolution micropatterning of a

Pedot: PSS conducting-polymer-silksericin composite is presented using a water-based, benchtop photolithographic process. Conducting microstructures formed on a flexible silk fibroin sheet allow a fully organic, flexible bioelectronic device. Large-area microfabricated devices such as biosensors that are biocompatible and degradable over a controlled period of time can be formed.

Keywords: biosensors; conducting polymers; photolithography; sericin composites.
