Fluorescence emission spectra of the trimera-TiO₂ NPs suspensions.

<p>The solution contains 5 μg/mL (60 nM) trimera and TiO₂ NPs at the concentrations of 0, 10, 40, 80 and 100 μg/mL in a final volume of 3 mL of buffer (PBS supplemented with 10 mM MgSO₄). The emission spectra were measured using an excitation wavelength of 290 nm as described in the Materials and Methods section. Results are representative of at least three independent experiments. In inset: enlargement of the fluorescence spectrum in the region 360-500 nm for three solutions. Fluorescence spectra of 5 μg/mL trimera alone (green), 100 μg/ mL TiO₂ NPs alone (red) 5 μg/mL trimera in the presence of 100 μg/ mL TiO₂ NPs (blue).
