“…Still, the obtained values (9.5 AE 1.0 N) were lower than the injectability of commercially available medical products (e.g. Radiesse 1 -a dermal filler, F MAX 27 N) (Ji et al, 2012) and were in the range of the injectability of tricalcium phosphates pastes proposed for bonegrafting applications (5.4 AE 1.1 N-18.5 AE 1.7 N) (Montufar et al, 2013).…”

“…Owing to their super strong water absorption ability, they have been extensively used in agriculture and forestry, construction, medical [4,5] and public health, and daily life supplies [6][7][8][9]. In fact,~90% of superabsorbent hydrogels are disposable products [10,11], and most of them are synthesized by the graft copolymerization between hydrophilic monomers with double bond such as acrylic acid (AA) and acrylamide (AM).…”

Abstract:In this study, the corn straw after removing the lignin was grafted with 2-acrylamido-2-methylpropanesulfonic acid (AMPS) to prepare sulfonated cellulose. The grafting copolymerization between the sulfonated cellulose and acrylic acid (AA) was performed using potassium persulfate and N,N 1 -methylenebisacrylamide as the initiator and crosslinking agent, respectively, to prepare corn straw-co-AMPS-co-AA hydrogels. The structure and properties of the resulting hydrogels were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, and dynamic rheometry. The effects of initiator, crosslinker, monomer neutralization degree, and temperature on the swelling ratio of the hydrogels were studied. The water retention, salt resistance, and recyclability of the corn straw-co-AMPS-co-AA hydrogels were also investigated. The optimum water absorptivity of the corn straw hydrogels was obtained at a polymerization temperature of 50˝C with 1.2% crosslinker, 1:7 ratio of the pretreated corn straw and AA, 2% initiator, and 50% neutralized AA.

“…4 Schematic showing the synthesis of N-palmitoyl chitosan (NPCS) and the pH-triggered hydrogelation of aqueous NPCS injected into the subcutaneous space of a rat model [57] was dissolved in 1 % acetic acid, and PG was added to the solution at a concentration range of 1-6 wt%. Following this, the pH of the solution was adjusted to 6.8 and the solution was incubated at room temperature for 24 h. The hydrogel showed slow degradation and maintained structural integrity when incubated in PBS for 60 days [61]. Li et al prepared a PEC hydrogel made of chitosan and phosphorylated chitosan as osteoblast carrier.…”

Research in the field of hydrogels has been actively growing for the past couple of decades. Hydrogels are crosslinked polymers with high water content. They can be prepared from natural, synthetic, and composite polymers using different chemical and physical crosslinking methods. Hydrogels have been widely explored for the delivery of bioactive molecules, drugs, and for other therapeutic applications. Chitosan-based hydrogels have unique advantages owing to their biocompatibility, biodegradability, antimicrobial activity, mucoadhesivity, and low toxicity. This chapter reviews the different methods used for preparing chitosan-based hydrogels and their applications as cell, protein, and drug delivery vehicles to support tissue regeneration.
