However, loading multiple drugs in the nanoparticles for drug delivery system may cause insufficient drugs or functional groups, which might let the nanomaterial have fewer functions. Therefore, making the mesoporous silica nanoparticles (MSNs) have photodynamic therapy function by doping lanthanide ions into the material structure, can evade this problem. Moreover, with the doping of lanthanide metals, the MSNs can have not only dual imaging functions of both magnetic resonance imaging and fluorescence, but also achieve photodynamic function. To feature the material with more function, chemotherapeutic drug-doxorubicin was loaded into the pores of MSNs and then bonded hyaluronic acid which is the active target and a gatekeeper, on the surface of MSNs. Finally, an all-in-one drug delivery system Hyaluronidase and pH-responsive mesoporous silica nanoparticles with dual-imaging activity for chemo-photodynamic therapy is synthesized. The first part in this experiment was to confirm the physical properties of the lanthanides dopped MSN and its photodynamic treatment effect. The second part was to confirm that each organic molecule had been successfully bonded to the surface of the MSN and achieve pH and Hyaluronidase response drug release effect, The last part was to prove that the drug delivery system had a significant anticancer effect through cell experiments. |
