Aminated Mesoporous Silica Nanoparticles, Methods of Making Same, and Uses Thereof

摘要

A mesoporous silica particle having 10 mole % to 65 mole % amine groups present in the silica of the particle and on the silica surface of the particle. The particle has Pm 3n symmetry and a size of 25 nm to 500 nm. Methods of making such particles from the low temperature reaction of silane precursor and amino silane precursors is provided. The particle can be used in applications such as imaging, drug delivery, catalysis, and CO2 sequestration.
