Impact of Core-Forming Segment Structure on Drug Loading in Biodegradable Polymeric Micelles Using PEG-b-Poly(lactide-co-depsipeptide) Block Copolymers

Table 3

Characterization of micelles versus drugs in 30% feed.

Drug^a	Drug loading (DL) (wt%)
	b-PLLA	b-PDLLA	b-PLGL𝟒𝟗	b-PLGF𝟒𝟗
Fluorescein	16.6	20.0	29.0	26.2
4-Aminofluorescein	3.0	4.7	7.3	7.2
Pyrene	0.5	0.6	0.6	0.7
Doxorubicin	30.3	28.6	29.7	29.8

DL (%) = (drug found)/(micelle found) (w/w) × 100.
aThe amount of drug in feed = 30 wt%.
