Figure 2From: Self-assembled nanoparticles based on modified cationic dipeptides and DNA: novel systems for gene deliveryDLS study showing Np formation by Lys-ΔPhe and Arg-ΔPhe with DNA. (a) Lys-∆Phe Nps + DNA. (b) DNA + Lys-∆Phe. (c) Arg-∆Phe Nps + DNA. (d) DNA + Arg-∆Phe. Peptide Nps interacted with DNA leading to change in their overall size (Rh). Data expressed as mean ± SD (n = 3).Back to article page
