Fabrication of microstructured electrodes via electroless metal deposition onto polydopamine‐coated polystyrene substrates and thermal shrinking

Abstract The ability to provide high sensitivity with small footprints makes miniaturized electrodes key components of biosensing, wearable electronics and lab‐on‐a‐chip devices. Recently, thin film deposition onto polystyrene films, followed by thermal shrinking has been used to produce microstructured electrodes (MSEs) with high electroactive surface area (ESA). Nevertheless, the high cost associated with film deposition through evaporation …
