Direct synthesis of thin-film carbon nanomaterials on oxide-coated silicon substrates
provides a viable pathway for building a dense array of miniaturized (micron-scale)
electrochemical sensors with high performance. However, material synthesis generally
involves many parameters, making material engineering based on trial and error highly
inefficient. Here, we report a two-pronged strategy for producing engineered thin-film carbon
nanomaterials that have a nano-graphitic structure. First, we introduce a variant of the metal …

Results Synthesis of nG carbon material. The illustrations in Fig. 1 show the main steps of
our synthesis method. An advantageous feature of our method is the production of small
micron-scale NG carbon islands from pre-patterned amorphous carbon directly on thermally
grown SiO2 substrates. This direct growth technique significantly simplifies the sensor
fabrication process because it avoids the common challenges associated with the graphene
transfer techniques such as the formation of cracks 49, 50, wrinkles 51, or the chemical …
