Fig. 5. Isothermal titration calorimetry (ITC) of β-cyclodextrin coated quantum dots (CD-QD) with chemical cargoes.

Fig. 5

Thermograms (top) showing the thermal power peaks corresponding to each chemical injection and binding isotherms (bottom) representing the enthalpy change determined by integrating thermal power profiles for CD-QD interacted with a methyl viologen and b ascorbic acid. The ITC results indicate that CD-QD exhibit a higher binding affinity to both methyl viologen and ascorbic acid than MPA-QD. Squares represent raw data and line represents best-fit curves using a one-set-of-sites binding model.
