“…Multiple, directional hydroxyl groups in the sugar part make it easier for sugar surfactants to form hydrogen‐bonding networks . The advantage of hydrogen‐bond formation is that sugar surfactants can form gels in various solvents, including water, organic solvents, and RTILs …”

Green and environmentally friendly ionogels formed by a sugar surfactant were prepared in two kinds of imidazolium-based ionic liquids. The phase transition from ribbon structures to lamellar structures induced by temperature and the transition mechanism were investigated in detail by means of freeze-fracture TEM and field-emission SEM observations, as well as small-angle X-ray scattering measurements. The rheological properties and tribological properties of two kinds of ionogels were systematically investigated. The difference in the lubricating properties and antiwear capability can be explained well by the mechanical and viscoelastic properties, as well as the different microstructures of samples destroyed by shear forces. This work provides a better understanding of the relationship between the structures, rheological properties, and tribological properties of ionogels.

“…At present, carbohydrate-based supramolecular hydrogels have begun to emerge as valuable scaffolds for multivalent carbohydrate recognition, [73][74][75] showing tight and specific binding to host cells. As one of the most important functional biomolecules, carbohydrates often play an extremely important role in a wide range of basic biological phenomena through carbohydrate-mediated multivalent interactions.…”

Supramolecular hydrogels: synthesis, properties and their biomedical applications

As a novel class of three-dimensional (3D) hydrophilic cross-linked polymers, supramolecular hydrogels not only display unique physicochemical properties (e.g., water-retention ability, drug loading capacity, biodegradability and biocompatibility, biostability) as well as specific functionalities (e.g., optoelectronic properties, bioactivity, self-healing ability, shape memory ability), but also have the capability to undergo reversible gel-sol transition in response to various environmental stimuli inherent to the noncovalent cross-linkages, thereby showing great potential as promising biomaterial scaffolds for diagnosis and therapy. In this Review, we summarized the recent progress in the design and synthesis of supramolecular hydrogels through specific, directional noncovalent interactions, with particular emphasis on the structure-property relationship, as well as their wide-ranging applications in disease diagnosis and therapy including bioimaging, biodetection, therapeutic delivery, and tissue engineering. We believe that these current achievements in supramolecular hydrogels will greatly stimulate new ideas and inspire persistent efforts in this hot topic area in future.

“…1A) according to a published procedure. 36,37 Briey, we prepared 6-O-acylated fatty acid ester of D-glucose by reacting it with O-O 0 -dilauroyltartaric acid anhydride. In a Teon lm tightened, septum-capped test tube 100 mg of 1 and 330 mL DI water were placed and then heated in an oven to 125 C for 2.5 h. Upon completion of the carbonization, the reaction mixture was cooled to room temperature yielding a brown precipitate indicating the formation of carbon dots and puried for further work.…”

A hybrid carbon-dot (C-dot)-hydrogel matrix was constructed and employed for detection of bacteria. The transduction mechanism is novel, based upon cleavage of ester bonds within the hydrogel scaffold by bacterially-secreted esterases; the ensuing fluidization of the hydrogel resulted in aggregation of the embedded C-dots and consequent quenching of their fluorescence. We show that the C-dot-hydrogel exhibits high sensitivity and can distinguish among bacterial species through modulation of the emitted fluorescence, depending upon their esterase secretions.
