In vitro hemolytic activity of PLGA-ALE NP (mean ± S.E. from 6 experiments). NP concentration was expressed as the amount of ALE in each sample (adapted from reference [37]).

Sample	NP concentration	% hemolysis
PLGA-ALE NP	0.56 ng/mL	0 ± 0.155
	5.6 ng/mL	0.167 ± 0.191
	56 ng/mL	0.356 ± 0.309
	0.56 μg/mL	0 ± 0.272
	5.6 μg/mL	0.289 ± 0.320
	56 μg/mL	0.001 ± 0.165
Saponin	-	132.7 ± 2.74
PBS	-	0
Distilled water	-	100
