The enzyme glucose oxidase is immobilized on a 3D matrix consisting of multilayered graphene petal nanosheets peppered with Pt nanoparticles. Glucose binds within the enzyme pocket producing H 2 O 2 , while consuming O 2 , during electrochemical glucose sensing. As reported on page 3399 by Timothy S. Fisher and co‐workers the size, morphology, and density of the Pt nanoparticles are manipulated to enhance sensor performance. Enzymes are enlarged to illustrate functionality.
