The association. constants (Ka) of their host–guest complexes are typically. several orders of magnitude higher than that of CDs.

Ka values areunaffected by the proportion of direct guest interactions withthe AuNP surface, if any. ... The obtained binding isotherms were used ascalibration curves through G2 = θ/(Ka Kaθ).

Wide-angle and low-angle X-raydiffraction (XRD) data were collected using a Siemens D5000 X-ray diffractometer with Cu Ka radiation (k = 1.5406 Å).
