This study demonstrates two cost-effective and efficient strategies with which to manipulate the morphology of gold nanostructures, and thus their catalytic properties, for the successful manufacturing of glucose fuel cells (GFCs). GFCs hold great promise as in- or on-body energy harvesters for ultra-low-power bioelectronics to enable the effective management of long-term diseases, minimizing the risk of associated complications. We have generated gold nanostructures via gold electrodeposition assisted by two types of soft template: a lipid cubic phase Phytantriol/Brij®-56, leading to a nanofeather-like Au structure, and an emulsion hexane/SDS, leading to a nanocoral-like Au structure. Both showed great sensitivity to glucose, with a 7 μW cm−2 maximum power density and an up to 70 μA cm−2 current density. View this paper
