Real-time in situ monitoring via europium emission of the photo-release of antitumor cisplatin from a Eu–Pt complex†
Abstract
A water-soluble light-responsive antitumor agent, PtEuL, based on a cisplatin-linked europium–cyclen complex has been synthesized and evaluated for controlled cisplatin release by linear/two-photon excitation in vitro with concomitant turn-on and long-lived europium emission as a responsive traceable signal.
