Decorating PtCo bimetallic alloy nanoparticles on graphene as sensors for glucose detection by catalyzing luminol chemiluminescence.

A new type of PtCo(x) @graphene nanocomposite is prepared by a simple chemical solution method, which can dramatically enhance the chemiluminescence (CL) intensity of luminol-H(2)O(2) system, making it possible for the detection of glucose through measuring the H(2)O(2) produced from its catalytic oxidation.
