Multifunctional mesoporous silica nanoparticles (MSNs) are good candidates for
multimodal applications in drug delivery, bioimaging, and cell targeting. In
particular, controlled release of drugs from MSN pores constitutes one of the
superior features of MSNs. In this study, a novel drug delivery carrier based on
MSNs, which encapsulated highly sensitive (19)F magnetic resonance imaging (MRI)
contrast agents inside MSNs, was developed. The nanoparticles were labeled with
fluorescent dyes and functionalized with small molecule-based ligands for active
targeting. This drug delivery system facilitated the monitoring of the
biodistribution of the drug carrier by dual modal imaging (NIR/(19)F MRI).
Furthermore, we demonstrated targeted drug delivery and cellular imaging by the
conjugation of nanoparticles with folic acid. An anticancer drug (doxorubicin,
DOX) was loaded in the pores of folate-functionalized MSNs for intracellular drug
delivery. The release rates of DOX from the nanoparticles increased under acidic
conditions, and were favorable for controlled drug release to cancer cells. Our
results suggested that MSNs may serve as promising (19)F MRI-traceable drug
carriers for application in cancer therapy and bio-imaging.
