Anthocyanin Encapsulated Nanoparticles as a Pulmonary Delivery System

Figure 2

The physical and chemical characteristics of HB anthocyanin-encapsulated nanoparticles. (a) The percentage anthocyanin encapsulation efficiency (EE), and (b) the percentage loading capacity (LC) at HB: polymer (w/w) ratio of 1 : 10 and 1 : 20. (c) Transmission electron microscopy images of the anthocyanin-loaded nanoparticles at 1 : 10 HB: polymer ratio. Yellow color arrows indicate the spherical shape of nanoparticles. (d) The particle size distribution of HB anthocyanin-encapsulated nanoparticles at 1 : 10 HB: polymer ratio. The results represent three independent experiments. One-way analysis of variance was performed () with Tukey’s pairwise comparison (at ) for mean comparison. indicates statistical difference at with . Scale bar =200 nm. PEG-PLGA : polyethylene glycol-poly(lactide-co-glycolide); MDX: maltodextrin; CMC: carboxymethyl chitosan.
