Laser-induced graphene (LIG) with a 3D hierarchical, porous structure benefits from a fast production process, low-cost starting materials and a relatively green nature . It can be considered as a rapid, pattering strategy, in which both production and patterning are carried out simultaneously, as compared to other graphene synthesis methodologies . Its high electrical conductivity and high surface area have made LIG a promising electrode material for devices that harness chemical and electrochemical processes, such as electrocatalysts, energy storage and conversion, sensing and biosensing . While the characteristic extended honeycomb lattice of graphene is absent throughout LIG structures, they usually possess numerous structural imperfections, such as pentagonal and heptagonal carbon rings and various functional groups, useful in the above-mentioned applications. LIGs can be postprocessed through various strategies to enhance their functionality or induce new properties . Their high surface area provides numerous sites for the (electro)deposition of nanoparticles, the grafting of various biomolecules and anchoring molecules, which are highly demanding for the detection of ionic species, small molecules and various biomarkers . In addition, regardless of polyimide (PI) foils, LIG can be directly engraved onto biodegradable and biocompatible substrates, such as paper and chitosan (CS) that are in-line with sustainable and green materials criteria . Lasing LIG with complex geometry on flexible substrates and the possibility to transfer it onto stretchable and adhesive hydrogels, conformal to natural skin, make it appealing for wearable bioelectronics, e-skin and soft robotics . However, there are challenges associated with LIGs, such as significant dependence of the produced LIGs on lasing parameters, utilized raw materials, such as the brand of PI foil, or even the environmental stability of the LIGs during storage .
