“…Currently, the creation of responsive ionically cross-linked hydrogels is done mainly through utilization of their pH and thermal responses. This approach was used for fabrication of calcium cross-linked alginate membranes actuated by chemoenzymatic systems [19,20], thermoresponsive alginate-PNIPAAm hydrogels [21,22], and electrical responsive alginate/poly(diallyldimethylammonium chloride) [23]. However, neither of these systems provides the spatial control that is necessary for fabrication of complex porous scaffolds and dynamic control of the gel formation and dissolution.…”

Iron(III) cross-linked alginate hydrogel incorporating sodium lactate undergoes photoinduced degradation, thus serving as a biocompatible positive photoresist suitable for photochemical patterning. Alternatively, surface etching of iron(III) cross-linked hydrogel contacting lactic acid solution can be used for controlling the thickness of the photochemical pattering. Due to biocompatibility, both of these approaches appear potentially useful for advanced manipulation with cell cultures including growing cells on the surface or entrapping them within the hydrogel.

“…There is much interest in developing humidity sensing materials for the fabrication of humidity sensing devices. A variety of materials have been utilized for humidity sensing, such as: polymers [2][3][4][5], electrolytes [6,7], and ceramics [8][9][10][11][12][13]. Among these materials, ceramics have been extensively investigated at both room and elevated temperatures [14].…”

“…Essentially, this is the result of electrostatic interactions between both polyions. PECs have been applied as membranes, [99] antistatic coatings, [100] environmental sensors, [101] chemical detectors, [29,102] and medical prosthetic materials. [103] Yoshizawa et al [104,105] prepared dual-sensitive PEC films composed of cationic chitosan and an anionic polyalkyleneoxide/maleic acid (PAOMA) copolymer to be applied as drug carriers.…”

In recent years, intelligent hydrogels which can change their swelling behavior and other properties in response to environmental stimuli such as temperature, pH, solvent composition and electric fields, have attracted great interest. The hydrogels based on polysaccharides incorporated with thermo-responsive polymers have shown unique properties such as biocompatibility, biodegradability, and biological functions in addition to the stimuli-responsive characters. These "smart" hydrogels exhibit single or multiple stimuli-responsive characters which could be used in biomedical applications, including controlled drug delivery, bioengineering or tissue engineering. This review focuses on the recent developments and future trends dealing with stimuli-responsive hydrogels based on grafting/blending of polysaccharides such as chitosan, alginate, cellulose, dextran and their derivatives with thermo-sensitive polymers. This review also screens the current applications of these hydrogels in the fields of drug delivery, tissue engineering and wound healing.
