From: DNA-encapsulated silver nanodots as ratiometric luminescent probes for hypochlorite detection
Luminescence titration of red silver nanodots with sodium hypochlorite. (a) Emission spectra were acquired 6 h after hypochlorite addition in 10 mM Triton X-100 and 5 mM sodium sulfate solution at pH 8.3. Inset: A close-up of the red region. (b) The plot of luminescence intensity ratio of I485/I625 against OCl− concentration. The data was fitted with a fourth-order polynomial function. The error bars represent the standard errors.
