A simple method developed at KAUST uses laser beams to create graphene electrodes that have better performance than those produced through older methods.
Electrodes consisting of graphene, an atypical form of carbon, may transform the way electroactive substances are detected and measured in numerous fields ranging from food safety and clinical diagnosis to environmental monitoring1,2,3.
Graphene comprises multiple ultrathin and highly ordered sheets of interconnected honeycomb-shaped rings of carbon atoms. This multilayered architecture provides the material with exceptional electronic properties, especially electrical conductivity and electrocatalytic activity, as well as physical features that are useful for making electrochemical sensors.
