A review on application of multifunctional mesoporous nanoparticles in controlled release of drug delivery

摘要

In the early 1990s the discovery of the MCM-41 and the M41S family of mesoporous materials had open new era in the chemistry and biology. They have prominent application in biotechnological, biomedical and heterogeneous catalysts. Mesoporous silica nanoparticles (MSNs) exhibit unique structural features like as their large surface areas, tunable pore sizes in nanometer and well-defined surface properties. MSN materials which are comprised of a honeycomb-like porous structure with hundreds of empty mesoporous channel that are able to encapsulate relatively large amounts of biomolecules. They are ideal candidate for constructing multifunctional materials that encapsulate a variety of functional nanostructured materials. Multifunctional MSN materials have become one of the most attractive areas in nanobiotechnology and nanomedicine for various disease diagnosis and therapy. Multifunctional MSN have been successfully developed as a multifunctional platform to deliver therapeutic and diagnostic agents. Multifunctional MSNs are a highly promising platform for intracellular controlled release of drugs. In this review we discuss the recent developments in design and fabrication of multifunctional mesoporous silica nanoparticles in as efficient drug delivery applications such as the site-specific delivery and intracellular controlled release of drugs.
