One-pot high-yield synthesis of Pd nanocubes for Pd-Ir nanocube-based immunoassay of nucleocapsid protein from SARS-CoV-2

Pd-Ir nanocubes are promising peroxidase-mimicking nanozymes for immunoassays, enabled by their excellent stability, relatively high catalytic activity, and reproducible performance. A key step involved in the preparation of Pd-Ir nanocubes is the synthesis of Pd nanocubes. However, the traditional method to synthesize Pd nanocubes requires sophisticated and expensive equipment to precisely control the reaction temperature and highly skilled …
