Figure 5From: Self-assembled nanoparticles based on modified cationic dipeptides and DNA: novel systems for gene deliveryTEM images showing location of DNA inside Arg-∆ Phe-DNA Nps (densely stained structures are the peptide Nps which entrapped DNA). DNA is labeled with electron dense Pt for aiding visualization under TEM. High magnification images clearly indicate the presence of DNA inside nanoparticle core. Scale bar 200 nm.Back to article page
