“…Therefore, β-cyclodextrin is able to form host-guest complexes with most surfactants' hydrophobic tails into cyclodextrin's cavities. Reported by Xu et al [21] confirmed that the accumulation of β-cyclodextrin to the non-ionic surfac-tant solutions leads to growth of the aggregates instead of their dissociation. The solutions undergo micellar growth and micelle to vesicle transitions.…”

“…Beyond 20 mg L -1 , the extraction efficiency of phenol decreases. It is speculated that if enough β-cyclodextrin is added to the micellar surfactant solution, all of the surfactant will eventually be complexed, resulting in the total breakdown of the micelles [32]. Thus, excess phenol is retained in the aqueous phase, resulting in a decrease of extraction efficiency of phenol in the CPE systems.…”

“…Low-molecular-weight HA can be produced by -irradiation or enzymatic degradation. 47,48 HA is abundantly distributed in natural ECM and is degraded by the enzyme hyaluronidase. In the native ECM, HA absorbs large amounts of water and expands to form a loose hydrated network, serving as a space filler, lubricant and osmotic buffer.…”

Owing to the high water content, porous structure, biocompatibility and tissue-like viscoelasticity, hydrogels have become attractive and promising biomaterials for use in drug delivery, 3D cell culture and tissue engineering applications. Various chemical approaches have been developed for hydrogel synthesis using monomers or polymers carrying reactive functional groups. For in vivo tissue repair and in vitro cell culture purposes, it is desirable that the crosslinking reactions occur under mild conditions, do not interfere with biological processes and proceed at high yield with exceptional selectivity. Additionally, the cross-linking reaction should allow straightforward incorporation of bioactive motifs or signaling molecules, at the same time, providing tunability of the hydrogel microstructure, mechanical properties, and degradation rates. In this review, we discuss various chemical approaches applied to the synthesis of complex hydrogel networks, highlighting recent developments from our group. The discovery of new chemistries and novel materials fabrication methods will lead to the development of the next generation biomimetic hydrogels with complex structures and diverse functionalities. These materials will likely facilitate the construction of engineered tissue models that may bridge the gap between 2D experiments and animal studies, providing preliminary insight prior to in vivo assessments.

“…The characteristic length (a c ) of the CMP and CNP aggregates was determined using Debye-Bueche plots (I À0.5 vs. q 2 ). 30,31 A linear t to the data plotted in the Debye-Bueche format was calculated in the ow or vorticity direction using the method of least squares. The slope and intercept of the linear t were used to calculate a characteristic length [a c ¼ (slope/intercept) 0.5 ] for the aggregates at various conditions.…”
