389 | Au@PtNP | 35.5 | 4.3 | nm | DLS | We found that the ions (1.0 μM) induced the slight aggregation of the Au@PtNPs, which was demonstrated by the average hydrate size change of the Au@PtNPs from 35.5 ± 4.3 to 75.0 ± 5.5 nm in Fig. 3 |

389 | Au@PtNP | Although these methods demonstrated advantages such as low cost and high selectiveness, the sensitivity needed to be improved further. In this work, we combined this Pb2+-S2O3 2−-based metal leaching with Au@PtNP nanozyme together to fabricate a new colorimetric determination of Pb2+. | pb2+ | Color | 20~800 | nM | 3.0 | nM |
