Glass transition temperature (T_g) and melting temperature (T_m) were determined from the second heating cycle. The melting enthalpy (ΔH) was calculated by integrating the corresponding melting peaks.

Mean particle diameter of blank NP and CPT-loaded NP determined by dynamic light scattering. Three measurements on the same NP compositions gave perfectly overlapping histograms.

LE: loading efficiency; EE: encapsulation efficiency. Values reported are mean ± standard deviation (n=3).
