Characterization of luminescent properties of LCD and LCD/PPV NPs. A Fluorescence spectra of PPV in a solvent mixture of H2O/THF with different proportions of water (fWater) at an excitation wavelength (λex) of 425 nm. B The emission spectrum of LCD in the presence of hypochlorite (ClO−) and the excitation spectrum of PPV (λem = 650 nm). C The luminescence spectrum of LCD/PPV mixture in DMF/H2O at 100 mM ClO−. D, E TEM image (D) and size distribution (E) of LAD NPs. F The luminescence spectrum of LAD NPs at 100 mM ClO−. G Time-dependent luminescence signals of various concentrations of LAD NPs upon incubation with 10 mM H2O2. H Time-lapse luminescence curves of 10 mg/mL LAD NPs upon incubation with various levels of H2O2. I A typical time-resolved luminescence curve showing sustained luminescence of LAD NPs in presence of H2O2. The photon counts were acquired immediately after 10 mg/mL LAD NPs were incubated with 80 mM H2O2
