“…1 a well formed graphite band was possible through utilisation of screen printing, with the resultant band exhibiting a typical screen printed carbon-graphite structure as has been well reported within the literature. [25][26][27][28] We do however note that under high magnication it is clear that a slight deviation from a perfectly straight microband occurs. Further to this it was apparent that during the screen printing process of the graphite layer for the production of the 50 mm microband, only a small number of prints ($5 sheets) was possible prior to the V-mesh becoming blocked with the larger sized particles present within the graphite ink which requires cleaning before further use.…”

We demonstrate the first example of the fabrication of co-planar 50 μm (width) screen printed graphite microbands (length: 20 mm), fabricated entirely via screen printing which are characterised both microscopically and electrochemically via cyclic voltammetry and evaluated towards the sensing of NADH offering a competitive limit of detection (3σ) of 0.24 μM. The fabricated electrodes are also shown to be extended to gold screen printed microbands which are evaluated towards the sensing of chromium(VI) offering a limit of detection (3σ) of 2.65 μM. These microbands are seen to be the first produced entirely through screen printed technology potentially allowing disposable, mass produced microbands to be realised.

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Ni-doped nanoporous carbons provided similar propargyl alcohol conversions for very low metallic contents. Nanoparticulated Ni on various carbon supports gave rise to the highest electrocatalytic activity in terms of product selectivity, with a clear dependence on Ni content. The results point to the importance of controlling the dispersion of the Ni phase within the carbon matrix for a full exploitation of the electroactive area of the metal. Additionally, a change in the mechanism of the propargyl alcohol electrooxidation was noted, which seems to be related to the physicochemical properties of the carbon support as well. Thus, the stereoselectivity of the electrooxidative reaction can be controlled by the active nickel content immobilized on the anode, with a preferential oxidation to (Z)-3-(2-propynoxy)-2-propenoic acid with high Ni-loading, and to propiolic acid with low loading of active Ni sites. Moreover, the formation of (E)-3-(2-propynoxy)-2-propenoic acid was discriminatory irrespective of the experimental conditions and Ni loadings on the carbon matrixes.

“…Como consequência, têm mostrado alta versatilidade de aplicações, tanto na forma de eletrodo convencional, quanto na forma de eletrodo modificado. [21][22][23][24][25][26][27][28][29][30][31][32][33] Ademais, dependendo da aplicação, esses eletrodos podem ser empregados muitas vezes, barateando ainda mais o custo das determinações analíticas.…”
