Biofunctionalized phospholipid-capped mesoporous silica nanoshuttles for targeted drug delivery
The present invention provides a multilayer vehicle, including a mesoporous silica core and a lipid bilayer coating thereon. Hydrophobic molecules are formed between the silica core and lipid layer. Additionally, methods and uses of the multilayer vehicle are also provided.
1. A multilayer vehicle, comprising:
a mesoporous silica core;
a 13-(chlorodimethylsilylmethyl)-heptacosane layer having a first terminal conjugated to a surface of the silica nanoparticle; and
a lipid monolayer modified on a second terminal of the hydrophobic molecule.
2. The multilayer vehicle according to claim 1 , wherein the silica nanoparticle has a pore ranged between 2 nm and 50 nm.
3. The multilayer vehicle according to claim 1 , wherein the lipid layer has a surface comprising a functional molecule.
4. The multilayer vehicle according to claim 3 , wherein the functional molecule comprises a target molecule, a genomic material, an aptamer, a protein, an antibody, a contrast agent and a folic acid.
5. The multilayer vehicle according to claim 2 further comprising an active material encapsulated in the pore of the silica nanoparticle.
6. The multilayer vehicle according to claim 5 , wherein the active material is one selected from a group consisting of a drug, a fluorescent agent, a protein, a polypeptide, an antibody, a radioactive material, a growth factor, an aptamer, and a genomic material.
7. The multilayer vehicle according to claim 5 , wherein the multilayer vehicle is a nanoshuttle.
8. The multilayer vehicle according to claim 7 , wherein the nanoshuttle is delivered by one selected from a group consisting of an oral administration, a transdermal, an injection and an inhalation.
