Abstract

3D optical manipulation of a thermal-sensing upconverting particle allows for the determination of the extension of the thermal gradient created in the surroundings of a plasmonic-mediated photothermal-treated HeLa cancer cell.

Keywords: luminescence nanothermometry; optical trapping; plasmonic in vitro heating.
