366	Pd−Ir core-shell nanoparticles	3.3–13.0		nm	TEM	Pd−Ir nanoparticles with four different sizes (3.3, 5.9, 9.8 and 13.0 nm), but identical shapes and surface structures, were designed and synthesized.								atalytic activity of individual Pd−Ir NPs increases as particle size increases. Area-specific catalytic activity is similar for Pd−Ir NPs of 3.3–9.8 nm, but is slightly decreased when particle size reached to 13.0 nm.

366	Pd−Ir core-shell nanoparticles	This work not only demonstrates the size effect, but also provides an effective strategy to enhance the performance of nanozymes in certain applications.			10- 2000	pg/mL	8.2, 4.6, and 3.7	pg/mL		the limit of detection (LOD, which was defined by the 3SD method33) for the ELISAs were lowered from 9.3, to 8.2, 4.6, and 3.7 pg/mL when the size of Pd−Ir NPs was reduced from 13.0 to 9.8, 5.9, and 3.3 nm, respectively.
