Fig. 2From: Fabrication and characterization of PLGA nanoparticles encapsulating large CRISPR–Cas9 plasmidProton NMR of materials making up nanoparticles. Analysis of F127 and PLGA proton NMR spectra show distinct peaks that can be used to determine polymer composition of resulting nanoparticles. 1H NMR spectra of a Pluronic F127 and b ester end capped PLGA c amine end capped PLGA in CDCl3Back to article page
