A phosphate-containing nanoparticle delivery vehicle includes a nanoparticle, an active ingredient, and a phosphodiester moiety connecting the nanoparticle and the active ingredient and forms a prodrug. The nanoparticle delivery vehicle achieves the function of increasing hydrophilicity of the active ingredient and specificity against tumor cells. Advantages of the nanoparticle material include biocompatibility, magnetism and/or controllable drug release. |
