Particle sizes of PS MPs (PS1 to PS5) used as templates and the pore size of the corresponding porous zirconia medium (PZrM) (sample codes: PZM1 to PZM5).

Sample code	Particle sizea [nm] (SEM)	Particle size [nm] (DLS)	PdI (DLS)	Sample code	Pore size [nm]
PS1	380 ± 85	380	0.109	PZM1	210 ± 40
PS2	520 ± 31	660	0.098	PZM2	380 ± 31
PS3	680 ± 18	750	0.204	PZM3	470 ± 39
PS4	970 ± 41	930	0.679	PZM4	650 ± 79
PS5	1010 ± 30	1010	0.664	PZM5	840 ± 82

^aThe particle size was the average values calculated from 100 of specimens obtained as SEM images.
