Composite micro-sensor for detecting free radical

A sensor and method for detecting free radicals in a sample includes providing an electrode at least partially coated with: an inner coating of a first material capable of catalyzing rapid electron transfer; and, an outer coating at least partially coating the inner coating. The outer coating can be a second material comprised of a cerium oxide/graphene composite.
