A synergistic graphene oxide–gold nanocluster (GO‐AuNC) hybrid has been constructed as an enzyme mimic that is able to show high catalytic activity over a broad pH range, especially at neutral pH. Importantly, the target‐functionalized hybrid has been applied as a robust nanoprobe for selective, quantitative, and fast colorimetric detection of cancer cells.
