(A) Schematic of N-doped porous carbon nanozyme (N-PCNS) with multiple enzyme-like activities. (B) TEM image of HFn loaded N-doped porous carbon nanozyme (HFn-PCN, left, scale bar 50 nm) and cancer cells treated with HFn-PCN (right, scale bar 500 nm). (C) Kinetic profiles of N-PCNS mimicking oxidase, peroxidase, catalase and SOD. N-PCNS-3 has a higher nitrogen doping ratio than N-PCNS-5 and showed a higher enzymelike activities. (D) Schematic of HFn-PCN mediated tumor cell death and photo images of tumors treated with HFn-PCN in comparison with different control groups. Tumor growth curves (E) and animal survival rates (F) after HFn-PCN treatment. Reprinted from ref. 43 with permission from Springer Nature, copyright 2018.
