Biomimetic hierarchical walnut kernel-like and erythrocyte-like mesoporous silica nanomaterials: Controllable synthesis and versatile applications
We developed a facile and controllable strategy to fabricate biomimetic walnut kernel-like mesoporous silica nanomaterial (WMSN) and erythrocyte-like mesoporous silica nanomaterial (EMSN). The former possesses unique multi-shell hollow structure and surface wrinkles while the latter has special multi-stack structure and bowl-shaped depression. These hierarchical materials with distinct structures can be finely tuned by changing the molar ratios of two surfactants, cetyltrimethylammonium bromide and 11-mercaptoundecanoic acid. The mechanism of structural formation through intermolecular interactions was revealed and validated experimentally. The promising potential applications of WMSN and EMSN in adsorption, cellular imaging, drug delivery, and cancer theranostics were further identified.
