We infer that N/B doping significantly increases/lowers the chemical interaction of graphene with individual CO molecules as a result of weak electrostatic forces induced by distinct charge distribution around the dopant site. High-resolution AFM images allow dopant discrimination and their atomic-scale structural characterization, which may be crucial for the atomic-scale design of graphene derivatives with relevant potential applications in molecular sensing and catalysis.
