| 7452 | 159 | Au@Pt | 50 | nm | TEM | A typical TEM image (Fig. 3) showed that the Au@Pt nanozymes were relatively uniform in size and similar in structure, and the diameter of the nanoparticles was approximately 50 nm. As a uniform porous structure, Pt NPs formed a branched structure on the surface ofAu. The particle size ofthe Au corewas approximately 30e35 nm, and the average diameter of the Pt NPs was approximately 5e10 nm. |

Moreover, the Kcat values for Au@Pt nanozyme were about 80e340 times higher than that of HRP, which indicated that the catalytic efficiency of Au@Pt nanozyme was stronger than that of HRP |
