Luminescence spectra obtained from NaYF4;Yb,Er@SiO2-ssDNA-N3 and DBCO-ssDNA-biotin able to produce interstrand ligation (blue line) and NaYF4;Yb,Er@SiO2-ssDNA-N3 and ssDNA-biotin, which are unable to produce interstrand ligation (red line), in the presence of 10–13 moles per well (1 nM) of target sequence and after washing the solid support with 10 mM of HEPES buffer and different concentrations of NaCl at 50 °C: 150 mM in (A) and 50 mM in (B).
