Fig. 3From: Fabrication and characterization of PLGA nanoparticles encapsulating large CRISPR–Cas9 plasmidUsing proton NMR to more accurately calculate DNA encapsulation efficiency. Mass ratio of Pluronic F127 and PLGA in the nanoparticles determined by proton NMR allows for more accurate calculations of encapsulation efficiency. 1H NMR of NPs made with Pluronic F-127 and a with ester end capped PLGA and b with amine end capped PLGABack to article page
