“…When comparing the Gemini‐type macromonomer D with its linear homologue B, D had a higher cmc value. As can be seen in Figure 3, two break points were observed in the surface tension curve of D. This observation was reported recently in random block polyelectrolyte polyester emulsifiers and in polymeric emulsifiers 19. If the cmc transition was assigned on the first break point, the value was similar to that of the linear homologue B.…”

“…The surface tension remarkable reduces when the block copolymer concentration decreases, owing to the absorption of block copolymer molecules on the air/water interface. The break of the curve is indicative of the cmc, above which the surface tension remains constant . The values of surface tension of surfmers are round 36 mN/m at the cmc, which are about 30 mN/m lower than that of the deionized water used in this case.…”

“…Both MS-MPs show fast, but controlled release of insulin, as illustrated by the low burst effect and the capacity of the formulation to maintain insulin release for more than 1 h. This contrasts with more uncontrolled profiles typical from some other CS-based delivery devices such as CS nanoparticles [38].…”

“…In a recent work that has addressed the interaction between CS and the surface of dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) bilayers, it has been observed that the increase of CS Mw leads to a dramatic reduction in the cooperative unit and hence an increase in effective contact area between individual CS and the lipid bilayer [37]. This reduction in the cooperative effective length against Mw implies that CS swirls across the surface bilayer, thus forming 'trains' [38]. 14 A similar mechanism may operate for the interaction between CS and MS-MP surface.…”
