Human α defensins human neutrophil peptide 1–3 (HNP 1–3) are potential prognostic cancer biomarkers. Metalloprotein anthrax lethal factor (ALF) binds to HNP 1–3 in a Zn2+-dependent manner. We conjugated ALF to the surface of magnetic nanoparticles (MNP) to magnetically isolate the HNPs, and used Zn2+ to control the capture and release HNPs.
