Abstract:
In this work, novel pH sensors based on biocompatible organic semiconductors are presented. The suitability of poly(3-hexylthiophene) (P3HT) and carbon nanotubes (CNTs) as sensing layers in aqueous media was investigated. The main advantage of this new form of pH sensors is their simplified architecture without a reference electrode. Good pH sensitivity was observed for both CNT sensors and P3HT sensors even with a small amount (60 (l) of the analyte. Although the CNT-based sensors were more rob...     »
