(A) Physico–chemical properties and technological characterization of samples. Values are mean ± SD (standard deviation) (n = 9) reported in brackets. (B) KLVFF release from NPs, (C) AFM analyses of CNT-NPs and (D) K-NPs. ^a polydispersity Index (PDI); ^b The results were expressed as intensity distribution (D(i)), i.e., the size below which is placed the 50% (D(i)50)) and 90% (D(i)90)) of all the particles; ^c the percentage of yield was expressed as the ratio of the recovered freeze-dried sample out of the total mass-weighted (polymer + drug) percent; ^d the percentage of encapsulation efficiency was expressed as the ratio of the encapsulated out of the total (encapsulated + free) drug percentage; ^e the drug content (loading capacity, LC) was expressed as the amount of the encapsulated drug in 100 mg of NPs.
