From: Ultrasmall metal alloy nanozymes mimicking neutrophil enzymatic cascades for tumor catalytic therapy
a HRTEM images, size distribution (n = 100 nanoparticles) and schematic illustration of five ultrasmall nanozymes. Scale bars = 5 nm. b The Pd content in five AuPd alloy nanozymes determined by ICP-OES (n = 3 independent experiments). c FTIR spectra of five AuPd nanozymes and SH-PEG-OMe. d Raman spectra of five AuPd nanozymes. e XRD patterns and (f) XPS spectra of five AuPd nanozymes. g Hydrodynamic diameter distribution of five ultrasmall nanozymes. All data are presented as mean ± STD. Source data are provided as a Source Data file.
