Like sponges, mesoporous silica nanoparticles (MSNs) can adsorb exceptionally large quantities of molecules in their interior spaces (pores) thanks to their high surface area – 5 g of MSNs possess the same surface area as an American football field. This high porosity can be controlled and adjusted by carefully synthesizing MSNs with a particular pore size. Learn more about mesoporous silica ❯
Other MSN materials are available by request, with customizations such as custom sizes, surfaces, pore structures, and larger quantities.
