제목 Novel multifunctional PHDCA/PEI nano-drug carriers (MPDCs) for simultaneous magnetically-targeted cancer therapy and diagnosis via magnetic resonance imaging (MRI)
초록 The MPDCs consist of ultra-sensitive magnetic nanocrystals as MR probes and for magnetic targeting, and a chemotherapeutic agent encapsulated in poly(hexadecylcyanoacrylate) (PHDCA) nanoparticles. The PHDCA nanoparticles were further coated with polycationic polyethylenimine (PEI) to enhance cellular uptake efficiency. Using organic solvent, 10.3 ±0.7 nm of monodisperse magnetic nanocrystals (Fe3O4) weresynthesized. To form the magnetic PHDCA nanoparticles (MPNs), magnetic nanocrystals in organic solvent and DOX were simultaneously encapsulated with the synthesized PHDCA using the emulsion solvent evaporation method. The anionic MPNs were coated with polycationic PEI.
