Expansion kinetics, and surface to volume S/V effects of chitosan II; elongation induced by 50 mM L-histidine and 0.1 M acetic acid, in 30mM phosphate buffer at pH 5.0. Approximate “half-life” time t1/2 for 50% of the maximum expansion: t1/2 = 42, 32 and 3 min for S/V = 10.0, 12.2 and 34.6, respectively [48].
