Synthesis and characterization of nano-encapsulated catechin by molecular inclusion with beta-cyclodextrin

► Increase in thermal stability of (BCD + CAT) with new endothermic peak at 250 °C. ► Raman spectra for (BCD + CAT) indicate inclusion complex formation. ► XRD patterns signify the change from crystalline to amorphous state for (BCD + CAT). ► Hence proved molecular inclusion of (BCD + CAT) at nano level.
