a) i) Schematics of cancer therapy based on the regulation of H₂O₂ enzyme catalysis. ii) The absorbance of O‐dianisidine at 460 nm was recorded after the treatment with the GOx (red curve), Lc‐CDots/GOx (Green curve), and Dc‐CDots (blue curve). iii) Representative tumor images of mice after undergoing different treatments with nano drugs.^{[ 105 ]} Reproduced with permission from ref.
