In this report, we describe the characterizations and applications of hybrid nanoparticles. These nanoparticles have been synthesized by combination of organometallic, polymerization process and functionalized with a specific peptide for targeting expressed serpin‐enzyme complex (SEC) receptor of human hepatoma HepG2 cells. By using peptide conjugated hybrid nanoparticles, the specific receptor targeting, collections of cells were successfully achieved. The cell collection results indicated that, the maximum up to 95.32% of HepG2 cell were collected. The 5‐dimethylthiazol‐2‐yl‐2,5‐diphenyltetrazolium bromide (MTT) assay of HepG2 cells incubated with these nanoparticles indicated that, the peptide conjugated hybrid nanoparticles did not possess significant cytotoxicity. The rotating magnetic field induced cell death studies indicated that, the HepG2 cell showed up to 70% of cell death was induced by hybrid nanoparticles under magnetic field. Concluding, these studies demonstrate that the hybrid nanoparticles have the capability of effective separation, imaging, targeting and killing of the human hepatoma cells.
