Comparison of the freeze-drying process with two cryoprotectants (sucrose and trehalose) at 5% and 10% w/v concentrations between samples of (a) CS-TPP NPs with P80 purified by centrifugation, (b) CS-TPP NPs with P80 purified by dialysis, (c) CS-TPP NPs with P188 purified by centrifugation, and (c) CS-TPP NPs with P188 purified by dialysis. A Particle size and (B) PDI. n = 3; two-way ANOVA, Tuckey's post hoc test. * p < 0.05 between freeze-dried samples and before freeze-drying. ** p < 0.05 between two samples
