Using such a simple and mild procedure as a treatment with water, the boron-rich phase is selectively removed, affording mesoporous pure silica nanoparticles with wormhole-like pores or, depending on the synthetic conditions, silica nanoshells.Drug-DeliveryFunctionalizationParticlesReleaseSystemSurfactant-free synthesis of mesoporous and hollow silica nanoparticles with an inorganic templatetext::journal::journal article::research article
