dc.description.abstractThe hydrophilic nature of sulfonated (SO3H) graphene was exploited to prepare aqueous inks with high concentrations and the development of disposable, flexible, and enzyme-free electrochemical glucose sensors is described. The inks were printed on the flexible substrates using inkjet printing method. Different polymeric flexible substrates, polyethylene terephthalate (PET) film, and polypropylene-based crystal clear A4 folder (CCF) were used as substrates. Micron-scale (similar to 4 mu m) electrode thickness with an average surface roughness of 14 nm was obtained. The changes in the sheet resistances of Pd/SO3H-rGO@PET and Pd/ SO3H-rGO@CCF after bending cycles were found to be 6.8% and 2.0%, respectively, confirming the high bending resistance of the deposited layers. The results showed that developed flexible sensors showed high electrocatalytic activities against glucose. Furthermore, CCF-based flexible sensors showed higher sensitivity [y (nA) = 0.52x (mM) + 12.15) with a wider linear range of 1-20 mM compared to PET-based sensors.en_US
