Near-infrared upconverting NaYF_4:Yb~(3*),Tm~(3*) nanophosphors modified with poly(acrylic acid) were prepared and characterized by transmission electron microscopy and luminescence spectroscopy.Based on the observed overlap between the emission spectrum of the NaYF_4:Yb~(3*),Tm~(3*) nanophosphors and the absorption spectrum of the gold nanorods,we believe that a new “turn-off luminescence resonance energy transfer aptamer sensor was constructed for sensing thrombin in near-infrared region.
Near-infrared upconverting NaYF_4: Yb ~ (3 *), Tm ~ (3 *) nanophosphors modified with poly (acrylic acid) were prepared and characterized by transmission electron microscopy and luminescence spectroscopy. Based on the observed overlap between the emission spectrum of the NaYF_4: Yb ~ (3 *), Tm ~ (3 *) nanophosphors and the absorption spectrum of the gold nanorods, we believe that a new ”turn-off luminescence resonance energy transfer aptamer sensor was constructed for sensing thrombin in near-infrared region.
