Abstract
The mesoporous carbon nanocube@mesoporous silica (mCNC@mSiO2) has a potential application as drug carriers because of its large surface area and low toxicity and biocompatibility. Hence, a novel double mesoporous material of mCNC@mSiO2 was prepared via a soft-template method. The mCNC@mSiO2 exhibited a uniform cubic morphology with large surface area of 545.9 m2 g–1 and average pore size of 7.94 nm. The drug capacity for mCNC@mSiO2 was 0.78 mg at concentration of 0.5 mg/mL for 24 h loading. Furthermore, after modified by poly(acrylic acid) (PAA), the mCNC@mSiO2@PAA drug capacity had changed from 0.78 to 1.009 mg at the same concentration as a cancer drug carrier due to electrostatic interaction between carboxyl and 5-fluorourail (5-Fu). The findings may show potential for MOF-derived carbon materials for bioscience applications.
