We present here an oncological application of radiopeptides that exploits the electrostatic attraction exerted by the negatively charged tumoral membranes. Appropriately modifying a human antimicrobial peptide, LL-37, we designed a functionalized radionuclides carrier capable of binding to the negatively charged tumor membranes, but not to the neutral healthy ones. We have carefully investigated by an extended molecular dynamics study the way in which the newly designed peptide interacts with tumor and healthy human cell membranes, proving by Potential Mean Force its high selectivity toward tumor membranes.
