Preparation of multifunctional mesoporous silica particles: the use of an amphiphilic silica precursor with latent amine functionality in selective functionalization of the inner surface: Using a sequential functionalisation strategy, scientists at Seoul National University, South Korea, have selectively modified the inner surface of mesoporous silica particles. To demonstrate their approach the team created silica particles that contained FRET donors inside the silica framework and Fret acceptor moieties inside the pore. The outer surface was also functionalised with hydroxypropyl groups. Functionalized mesoporous silica particles have a range of applications including catalysis, separation, sensing, and delivery. The team believe that this approach could help tailor the properties of mesoporous silica particles to suit different applications.
