Figure 3From: Antitumor activity of sorafenib-incorporated nanoparticles of dextran/poly(dl-lactide-co-glycolide) block copolymer1H NMR spectra. Sorafenib in DMSO (a); SORA-NP, sorafenib-incorporated nanoparticles in DMSO (b); and SORA-NP in D2O (c). The box shows typical peaks of sorafenib (a), and the arrow shows typical peaks of PLGA (b).Back to article page
