Figure 2. ELPAs self-assemble micelles with a low critical micelle concentration (CMC).

Figure 2

dpA3 was assessed for micelle assembly using pyrene and dynamic light scattering. (a) Emission spectra of pyrene as a function of dpA3 concentration. A decrease in the intensity of spectra was observed with decreasing concentrations of the conjugate. (b) L1/L3 was plotted against log(concentration) of the dpA3 conjugate, where L1 and L3 are the intensity at 373, and 384 nm respectively. The CMC for dpA3 conjugate was determined to be below 1.7 μM at the position indicated by the arrow. (c) Particle size distribution of dpA3 at 1000 μM in 10mM HEPES buffered saline using dynamic light scattering (DLS).
