Ultrahigh-water-content biocompatible gelatin-based hydrogels: Toughened through micro-sized dissipative morphology as an effective strategy

3D printing of jammed self-supporting microgels with alternative mechanism for shape fidelity, crosslinking and conductivity

“…The length of the PGMA segment was controlled via concentration of glycidyl methacrylate monomer used in the oil phase of the emulsion reaction. Determination of the epoxide value confirmed the presence of longer segments of Mgel III compared to Mgel II as detailed in literature [28]. Finally, the microgels were centrifuged and then washed 2 times with distilled water, 5 times with ethanol: distilled water (40:60 v/v) solution, and again 2 times with distilled water.…”

“…The microgels are prepared according to our previous work [28]. In brief, for preparation of Mgel II and Mgel III , a reverse emulsion polymerization protocol was performed by dropping an aqueous solution containing vinyl-functionalized gelatin, acrylic acid and an initiator (ammonium persulfate) into an oil phase containing water-insoluble glycidyl methacrylate monomer.…”

“…In this study, we introduced the new concept of jammed microgels aggregated via a novel crosslinking system. Aimed at this, gelatin microgels (Mgels) comprising superficial hydrophobic interactions were recruited, which provide self-supporting filaments due to the presence of satisfactory interactions between the extruded microgels [28]. A mixture (G-gel) of Mgels with pure thermo-sensitive gelatin molecules can present stable filaments with self-supporting characteristics and high fidelity after deposition.…”

Superabsorbent cellulose-based hydrogels cross-liked with borax

“…This might be owing to the limited content of cellulose which could be interacted with tetrahydroborate ions. It was worth noting that the swelling ratio of the prepared cross-linked hydrogels was higher than that of hydrogels previously reported 60 , 65 . When hydrogels are stimulated by temperature, pH, ionic strength, magnetic field, and radiation, the hydrogel materials would either swell or shrink 66 , 67 .…”

Control of eriocitrin release from pH-sensitive gelatin-based microgels to inhibit α-glucosidase: an experimental and computational study

“…MGs are prepared according to the previously reported method. 28 In brief, gelatin methacrylate was synthesized and used for the preparation of MGs. A reverse emulsion polymerization protocol was performed by dropping an aqueous solution containing gelatin methacrylate, AAc, AM, and initiator into the oil phase containing surfactant Span 60.…”
