title: Luminescence resonance energy transfer from an upconverting nanoparticle to a fluorescent phycobiliprotein.
abstract: Water dispersible upconverting polyethylenimine (PEI)-capped NaYF(4) nanoparticles co-doped with trivalent erbium (Er(3+)) and ytterbium (Yb(3+)) were prepared via solvothermal synthesis with an 18 nm average particle diameter. These upconverting nanoparticles can be used to sensitize a light-harvesting phycobiliprotein (R-Phycoerythrin) via luminescence resonance energy transfer (LRET).
