Title: Nd{sup 3+} doped LaF{sub 3} nanoparticles as self-monitored photo-thermal agents

In this work, we demonstrate how LaF{sub 3} nanoparticles activated with large concentrations (up to 25%) of Nd{sup 3+} ions can simultaneously operate as biologically compatible efficient nanoheaters and fluorescent nanothermometers under single beam (808 nm) infrared laser excitation. Nd{sup 3+}:LaF{sub 3} nanoparticles emerge as unique multifunctional agents that could constitute the first step towards the future development of advanced platforms capable of simultaneous deep tissue fluorescence bio-imaging and controlled photo-thermal therapies.
