Figure 3From: DNA-encapsulated silver nanodots as ratiometric luminescent probes for hypochlorite detectionComparison of the chemical stability of several silver nanodots towards oxidants. (a) The spectral shift of the near-IR emitter in the presence of oxidants. (b) The emission spectra of the near-IR, the red, yellow, and green emitters were recorded in the absence (marked as control) and presence (marked as 1 h) of oxidants.Back to article page
