Application of Solvent-Casted Gelatin Films for Environmental Remediation and Wastewater Treatment Purposes | Chapter 8 |Chemistry and Biochemistry: Research Progress Vol. 5

Gelatin, derived from collagen through partial hydrolysis, is widely recognized for its effectiveness in film formation and diverse applications across various industries. Despite its effectiveness, gelatin films encounter challenges such as poor water solubility and limited adsorption capacity for heavy metals, which restrict their broader application in environmental remediation. This study aims to enhance the practical applications of gelatin films in environmental remediation and contribute to the development of sustainable materials. In the study, gelatin films were prepared by dissolving gelatin in distilled water with mechanical stirring, followed by casting the solution into films. The physico-chemical properties of the films were evaluated. The biodegradability of these films was confirmed through soil burial tests, and their rapid dissolution in water was evident, with a measured water solubility of 29 ± 1.6%. The structural integrity and thermal stability of the films were characterized using UV and FTIR. The films exhibited significant UV-visible light absorbance, with a peak at 300 nm within the 280 to 480 nm range. FTIR spectra revealed the characteristic amide peaks of gelatin, indicating the presence of key functional groups. This research also highlighted the films' ability to adsorb copper ions from acidic solutions, as demonstrated by iodometric titration, and to treat hard water through complexometric titrations. These findings illustrate the potential of gelatin films as effective adsorbents for copper ions and water hardness, making them promising candidates for environmental remediation and wastewater treatment. These characteristics align with green chemistry principles, emphasizing the importance of environmentally friendly technologies in addressing heavy metal pollution. The study highlights rapid water solubility as a critical limitation of gelatin films, restricting their functionality in aqueous and humid environments. Addressing this challenge could significantly enhance their stability and expand their potential applications in environmental remediation and water treatment technologies.

A Study of the Thermal and Mechanical Properties of Gelatin-based Bioplastics| Chapter 4 | Current Advances in Geography, Environment and Earth Sciences Vol. 7

 Natural biopolymer proteins arisen fibrous insoluble collagen are usual by a wide range of commerces because of their ability to maintain and to be controlled easily. Scientists are interested in verdict alternative polymers of plastic that supply food safety in addition to being environmentally friendly. In this study, an inquiry was carried out to determine the possessions of gelatin as a bioplastic polymer for substitute of artificial film. This polymer is widely used as packing fabrics because of their good degradability and sustainability. In the laboratory, jam-based biofilms are produced by resolution casting in petri dishes. The results of qualified biofilms shows week stiffness (6.38 ± 0.20) and Break point elongation (611 ± 0.56) with separation energy 17 kJ/mol. However, 80% degradation worked out in gelatin biofilm with important protection given by gelatin coatings on food matters. Therefore, for strength, it is urged that to be mixed with the amount of synthesis and jam polymer, so it meets all the packing industry's accomplishment requirements.

Fabrication of Xanthan Gum: Gelatin (Xnt:Gel) Hybrid Composite Hydrogels for Investigating Skin Wound Healing Efficacy | Chapter 12 | Current Advances in Chemistry and Biochemistry Vol. 9

 Fabrication of hybrid hydrogels to improve biological characteristics or mitigate biomaterial drawbacks has become a prominent method. With the growing threat of skin wounds to public health and the economy, this study was conducted using xanthan gum (Xnt), citric acid (C), gelatin (Gel), glutaraldehyde (G), and HPLC-grade water to fabricate a series of composite hydrogels, including Xnt, Xnt:C, Xnt:Gel(3):G, Xnt:C:Gel(3):G, X All of the composite hydrogels comprised more than 90% water, according to physicochemical analysis. Swelling ability, biodegradability, excellent polymeric networks, and porosity were all demonstrated in the hydrogels. The existence of bound water and free, intra and inter molecule bound hydrogen linked OH and NH in the hydrogels was confirmed using Fourier Transform Infrared Spectroscopy (FT-IR). When compared to controls, all of the hydrogels showed considerable wound healing power in experimental deep second-degree skin burns in rats. Xnt:Gel(3):G, Xnt:Gel(5):G, and Xnt:C:Gel(5):G-treated wounds recovered faster than those treated with other composite hydrogels 20 days after application. The presence of Gel in the formulations may account for the maximum wound contraction of these hydrogel composites. Xnt:Gel(3):G, Xnt:Gel(5):G, and Xnt:C:Gel(5):G may be useful wound dressing materials, according to our findings.

Biodegradable Interpenetrating Polymer Network Hydrogel Membranes for Controlled Release of Anticancer Drug: Advanced Study | Chapter 8 | Trends in Pharmaceutical Research and Development Vol.2

Biodegradable interpenetrating polymer network hydrogel membranes of chitosan and gelatin were prepared by solvent casting evaporation method for the controlled release of 5‑fluorouracil (5‑FU), an anticancer drug. The membranes were characterized by Fourier Transform Infrared Spectroscopy (FTIR), differential scanning calorimeter (DSC), X‑ray diffraction (XRD), scanning electron microscopy (SEM) and Tensile strength measurements. The FTIR was used to understand the formation of crosslinking and to confirm the absence of chemical interactions between drug and membranes. DSC and XRD studies were performed to understand the crystalline nature of drug after encapsulation into the membranes. SEM was used to study the surface morphology of the membranes. The in vitro studies were carried out in phosphate buffer pH 7.4 at 37°C. The results of controlled release tests showed that the amount of 5‑FU release increased with the increasing the amount of gelatin in the membrane. Moreover, the release rate of drug increased as the amount of drug loaded in the membranes increased. All the results indicated that the prepared membrane was potentially useful in drug‑delivery systems, and the prolonged release rate was observed up to 12 h.
