7819	593	CeO2				TEM	The resulting CeO2 nanozymes obtained by a simple solvothermal protocol are in highly morphological uniformity and dispersity (Fig. 1a and S1a) with an average size of 31.1 ±3.9 nm (Fig. 1c). The STEM image (Fig. 1b) shows a flower-like morphology assembled by tiny nanoparticles with an average size of 6.1 ± 1.6 nm.
7872	656	CeO2	3~4		nm	XRD	The synthesized CeO2 were uniform in size and the estimated average diameter was between 3 and 4 nm.								The small and uniform particle size provides a larger specific surface area and more active sites, leading to superior enhanced performance in electrochemical detection.
7983	777	CeO2				SEM	Hollow CeO2 microspheres were shown to range in size from 1 to 3 µm, with the outer shell composed of smaller CeO2 particles of 20 nm average size (Figure 1).	28.0
7985	778	CeO2	92.04		nm	DLS	The Fig. 2I showed that the average size of CeO2, CeO2@APTES and CeO2@Ce6 was respectively 92.04 nm, 100.37 nm and 124.48 nm.
8156	1090	CeO2	2、10		nm	TEM	TEM images (Figure S1) reveal the presence of well-defined nearly monodisperse nanoparticles with average sizes of 2 and 10 nm, respectively.
8172	1108	CeO2	5		nm	TEM	All around 5 nm as determined from high-resolution transmission electron microscopy (HRTEM) and dynamic light scattering (DLS) (Figure 1a–e).
8177	1112	CeO2				SEM	As presented in Fig. 1a, the as-prepared CeO2 shows rod-like and porous characteristics with a diameter of ～7 nm and a length of 40～70 nm.	82.5
8251	1227	CeO2	5		nm	TEM	CeO2 nanoparticles were around 5 nm in size
8264	1245	CeO2	80-200		nm	TEM	The particle size distributions and potentials of the nanovesicles are presented in Figure 2I,J, respectively. The DLS analysis indicated that the nanovesicles ranged between 80 and 200 nm in size
