Many synthetic biomimetic nanocrystalline apatites are used as nanocarriers to produce multifunctional nanoparticles, by coupling them with the chemotherapeutic drug, such as Gefitinib, Dox or membrane antibody DO-24 monoclonal antibody (mAb) directed against the c-Met/Hepatocyte Growth Factor Receptor (Met/HGFR), which is over-expressed on different kinds of carcinomas and thus represent a useful tumor target recently [6–8]. The gene discussed is MET; the disease is carcinoma.
