This study aims to comprehend the mechanism of in situ crosslinking of gelatin (Gel) with tannic acid (TA) in an unoxidized environment due to TA's biocompatibility, hydroxyl group abundance, and non‐covalent bonding capability. The crosslinking of gelatin in an unoxidized medium offers advantages over oxidized, including enhanced biocompatibility and simplified reaction conditions. In this study, 20% (w/v) gelatin was crosslinked with varying TA percentages at 45°C, followed by electrospinning to obtain fibrous mats using acetic acid (AA) as the solvent. Increasing TA content resulted in a transition from nanoscale to microscale fiber diameter, indicating increased intermolecular and intramolecular hydrogen bonding. The tensile strength of Gel/TA‐5% was 5.6 MPa, surpassing the Gel/TA‐18% sample, suggesting fewer grafting and branching reactions within TA itself. The stability of the gelatin matrix was evaluated through fiber degradation rates within the initial 7‐day period, with percentages of 25%, 38%, 50%, and 85% observed for 18%, 15%, 10%, and 5% TA concentrations, respectively. The swelling percentage of fibrous mats in a buffer solution of pH 7.4 was highest for Gel/TA‐5% at approximately 290%. At lower TA concentrations, the crosslinking density is constrained; hence, progressive fiber disassembly at pH 7.4 improves the TA release, resulting in greater antibacterial efficacy in the first 4 h. Thus, electrospun fibers from in situ crosslinked gelatin with TA in an unoxidized medium holds promise for applications such as drug delivery and wound dressing, owing to the improved properties and enhanced release capabilities of the resulting gelatin‐based fibers

“…The Fourier-transform infrared spectra (FT-IR) of the AB45 dye, pristine FS and dyed scales showed the absorption characteristic peaks for the functional groups of dye, peptide (amide) groups of collagen in FS, -NH-C(=O)-, labelled as Amide A, Amide I, and Amide II, together with the bands typical to absorbances for phosphate and carbonate ions in the apatite lattice containing hydroxyapatite, Ca 10 (PO 4 ) 6 (OH) 2 , and calcium carbonate, CaCO 3 , are presented in Figure 1A,B [14,15]. The presence of characteristic peaks for the functional groups of AB45 in dyed FS confirmed the absorption of dye by the scales.…”

In the present article, the commercial value of fish scales (FS), one of the most discarded fish wastes, has been identified by discovering their gelation capability. Fish scales of different physical forms were applied for the removal of dyes (acid red 1 (AR1), acid blue 45 (AB45), and acid yellow 127 (AY127)) from textile dye solution by absorption process. An astounding phenomenon, gelation of the treated solution, was noticed when it was aged for a certain period. The absorption of dye by FS was confirmed and quantified by FT-IR and UV-visible spectroscopy analyses, respectively. Process optimization revealed that pristine FS showed better gelation efficacy compared to pulverized FS. The gelation process was successful only when the dye solution contained acid and salt. As most of the textile effluents contain acids and salts in the discarded dye solution, this gelation process implies an obvious indication of the saving process and chemical cost in textile waste treatment. The jellified wastewater was characterized by exploring the rheological properties. Based on these analyses, potential application areas have been discussed.
