Additional file 2: Figure S2. of Control of Alginate Core Size in Alginate-Poly (Lactic-Co-Glycolic) Acid Microparticles LioDaniel YeoDavid XuChenjie 2016 Calcein encapsulation efficiency for alginate-PLGA microparticles containing different sizes of alginate core. Alginate-PLGA microparticles containing 10 and 50Âľm alginate cores (homo-mag and vort-mag) demonstrated the high calcein encapsulation efficiency as compared to mag-mag alginate-PLGA microparticles.
