Structure parameters, PTX-loading efficiency, and zeta potential of the fabricated samples (MSN, H-MSN, and DESN).

Sample	SBET (m2/g)	D (nm)	Vpore (cm3·g−1)	PTX-Loading Capacity	Zeta Potential a (mV)
MSN	1000	2.38	1.089	12.4%	−16 ± 1
H-MSN	640	2.30	0.56	-	−58 ± 2
DESN	247	2.17	0.28	14.83%	65 ± 3

^a Zeta potential were measured in PBS (pH = 7.4) at room temperature.
