Figure 1. Micelles properties and surface oligoarginine presence.

Figure 1

(A) Schematic representation of the micelles formed and the relevant molecular weights of the components. (B) 1H NMR analysis of the peptides (CR8 and CR15) and micelles (mPEG-PLA-R8, mPEG-PLA-R15Low, and mPEG-PLA-R15High) showing the arginine α proton (1; δ = 4.40 ppm, 1H), δ protons (2; δ = 3.20 ppm, 2H), or ω-terminal methoxyl protons (arrow; δ = 3.40 ppm, 3H).
