Solvent-induced lysozyme gels: Rheology, fractal analysis, and sol–gel kinetics

MWNT-hybrided supramolecular hydrogel for hydrophobic camptothecin delivery

“…7 showed the effect of the α-CD content on the hydrogel strength by measuring G′ as a function of angular frequency. We found that the G′ value for all samples was independent of the frequency for the hydrogel samples investigated, which confirms that the resultant supramolecular hydrogels behave as a gel or "solidlike" fluid [30]. Moreover, a significant increase in G′ was observed with the increase of the α-CD contents, which indicated that α-CD could enhance the hydrogel strength.…”

Rheological study of giant squid surimi (Dosidicus gigas) made by two methods with different cryoprotectants added

“…Conversely, a gel with low n values presents a higher fractal dimension and is said to be tight (Nyström et al, 1996). Fractal dimensions for six samples (surimi, suwari-gel and definitive-gel) are shown in Table 7; their values are similar to other protein gels (Marangoni et al, 2000;Da Silva and Arêas, 2005;Maltais et al, 2007). It was observed that the viscoelastic colloidal structure of B surimi presented a higher D f and hence larger networks, as floc-floc interactions were weaker, thus permitting reticular expansion.…”

Pluronic F68 enhanced the conformational stability of salmon calcitonin in both aqueous solution and lyophilized solid form

“…As seen, the G′ , G″ and loss tangent remained almost constant and then suddenly changed when the strain increased from 0.1 to 100%. A sudden decrease of the G′ and a sudden increase of the G″ or loss tangent indicated the bond breakage within the hydrogel network and a transition from linear to nonlinear behavior 41, 42. In this case, the strain of 1.0% was determined for linear viscoelastic measurements.…”
