A biocompatible surface-functionalized nanoparticle was designed to sense phosphatidylserine exposed on apoptotic cells. We conjugated synthetic artificial phosphatidylserine binding ligands in a multivalent fashion onto magnetofluorescent nanoparticles. Our results show that (1) the synthetic nanoparticles bind to apoptotic cells, (2) there is excellent correlation with annexin V staining by microscopy, and (3) FACS analysis with nanoparticles allows the measurement of therapeutic apoptosis induction. The described nanomaterials should be useful for a variety of biomedical applications including in vivo imaging of apoptosis.
