Abstract

© 2018, Springer Science+Business Media, LLC, part of Springer Nature. Mono-dispersed spherical MCM-48 mesoporous silica nanoparticles (MSN) with cubic Ia3d mesostructure were synthesized under different stirring conditions using hexadecyltrimethyl ammonium bromide as structure directing agent and EO20PO70EO20 copolymer as particle size control. Results indicated that the EO20PO70EO20 works well in the reduction of nanoparticle size. In addition, increasing the stirring rate transformed mesoporosity from 2-D hexagonal P6mm to 3-D cubic Ia3d. The biomolecule adsorption properties of prepared ultra small nanoparticles of MCM-48 were compared with that of MCM-48 with ten times larger particle s..
