摘要：

Point-of-care testing (POCT) plays vital role in clinic field, especially in resource-limited areas. The nanozyme-based colorimetric platform is the potential strategy for POCT. Therefore, a high-entropy allay nanozyme (HEAzyme) was prepared via formaldehyde-assisted metal-ligand crosslinking method using multi-metal (FeCuAgCeGd) species. The obtained FeCuAgCeGd-HEAzyme showed coordination nanoparticles with ultrafine size (average size was approximately 5 nm). The peroxidase-like (POD-like) activity of FeCuAgCeGd-HEAzyme was verified through density functional theory (DFT) calculations, demon...
