Abstract The anticancer drug doxorubicin (DOX) is locked in the mesoporous silica nanoparticle by coating FeIII-TA polymer, and its burst release can be achieved under acidic environment, along with the decreased longitudinal relaxivity. This nanoplatform shows great potential to monitoring the drug delivery process and the fate of the nanocarrier.

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 inbiotechnological, 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.Abbreviations;APTES; 3-aminopropyl triethoxy sialne, ATP; Adenosine triphospahate, CD; cyclodextrinCPT; camptothecin, CS; Chitosan,CTAB; cyltrimethylammonium bromide,DNA; Deoxyribonucleic acid,DOX; doxorubicin,EDC; 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide,FD; fluorescein disodium,FSP;Fluroscent particle ,IBU;ibuprofen,MCM; mobil composition material, MPS; 3-trimethoxylsilyl propyl methacrylate, MS; mesoporous silica,MSN; mesoporous silica nanoparticle, MSNs; mesoporous silica nanoparticles,MSNP; mesoporous silica nanoparticle,NPS; nanoparticles;PFDTES;perfluorodecyltriethoxysilane, PAA; polyacrylic acid,PR;photo responsive,PMAA; polymethyl methacrylate,SBF; simulated body fluid,TEOS;tetraethyl orthosilicate,TUNA;Thio undecyl-tetraethyleneglycoestero-nitrobenzylethyldimethyl ammonium bromide.
