“…Thus, using Ag as the backing material, instead of Pt, reduces the fabrication cost of the pressed discs. These findings are interesting as Ag substrates are used throughout the literature for numerous electrochemical applications including OER, biomolecule immobilisation and glucose sensing [25,30,31].…”

The screening of new OER materials routinely involves fabricating electrodes from powders using methods which are often time consuming and may involve using solvents and/or conductive materials that can alter the OER activity of the powder. Herein, a new mechanical, solvent-free method for fabricating electrodes for OER is described in which a electroactive material under test, mixed with a small amount of PTFE powder (ca. 10 wt%), is pressed onto Pt powder to create a permanent, robust electrode that can be used in a rotating disc electrode setup. This new method of fabricating electrodes is compared to the well-known dropcast on Glassy Carbon (GC) method, using commercially available materials: RuO 2 , Co 3 O 4 and NiO. The results show that the mechanical route produces much better OER performances, in terms of overpotential and stability, for the commercial metal oxide on the pressed discs when compared to the dropcast GC method. Finally, it is shown that this mechanical, high surface area, solvent-free electrode fabrication technique can also be achieved using silver, rather than platinum, as the conducting, support material.

A novel and highly sensitive disposable glucose sensor strip was developed using direct laser engraved graphene (DLEG) decorated with pulse deposited copper nanocubes (CuNCs). The high reproducibility (96.8%), stability (97.4%) and low cost demonstrated by this 3-step fabrication method indicates that it could be used for high volume manufacturing of disposable glucose strips. The fabrication method also allows for a high degree of flexibility, allowing for control of the electrode size, design, and functionalization method. Additionally, the excellent selectivity and sensitivity (4,532.2 μA/mM.cm2), low detection limit (250 nM), and suitable linear range of 25 μM–4 mM, suggests that these sensors may be a great potential platform for glucose detection within the physiological range for tear, saliva, and/or sweat.
