摘要: A simple and fast fabrication method to create high-performance pencil-drawn electrochemical sensors is reported for the first time. The sluggish electron transfer observed on bare surfaces was enhanced using two steps: oxidizing surface then reducing it in a subsequent step. heterogeneous rate constant found be 5.1 × 10–3 cm s–1, which highest value so far surfaces. We mapped origin of such performance by atomic force microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy. Our results suggest that oxidation process leads chemical structural transformations electrode surface. As proof-of-concept, we modified with Meldola’s blue electrocatalytically detect nicotinamide adenine dinucleotide (NADH). device exhibited catalytic (1.7 105 L mol–1 s–1) lowest detection potential NADH paper-...
