Considering the sustainable development goals to reduce environmental impact, sustainable sensors based on natural polymers are a priority as the large im plementation of these materials is required considering the Internet of Things (IoT) paradigm. In this context, the present work reports on sustainable blends based on collagen and different ioni...

Wool, choline dihydrogen phosphate ([Ch][DHP]) or choline serinate ([Ch][Seri) ionic liquids (ILs) were incorporated into native collagen formulations and films were prepared by compression moulding. Scanning electron microscopy (SEM) images showed no agglomeration, indicating good dispersion of additives within films. The denaturation peak observe...

Native collagen doughs were processed using a syringe-based extrusion 3D printer to obtain collagen scaffolds. Before processing, the rheological properties of the doughs were analyzed to determine the optimal 3D printing conditions. Samples showed a high shear-thinning behavior, reported beneficial in the 3D printing process. In addition, tetrahyd...

By‐products generated from food processing industries, rich in proteins and polysaccharides, have been reported as potential sources for the development of food packaging materials. Therefore, the valorization of these abundant and available biowastes can be a worthy approach to prepare sustainable and value‐added products. Among others, fish canni...

Biodegradable polymers obtained from renewable resources, such as chitosan and collagen, are sustainable alternatives to develop environmentally friendly materials. Due to their abundance, biocompatibility and antimicrobial properties, chitosan and collagen could become a suitable source for food and biomedical applications. In particular, chitosan...

Collagen was obtained from porcine skin by mechanical pretreatments with the aim of preserving the triple helix structure of native collagen, which was indirectly corroborated by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) results. Moreover, aloe vera (AV), with inherent biological properties, was inco...

Native collagen scaffolds were prepared in this work, in which both materials and environmental approaches were considered with the aim of providing a global strategy towards more sustainable biomaterials. From the environmental perspective, it is worth mentioning that acid and enzymatic treatments have been avoided to extract collagen, allowing th...

Chitosan/collagen films were developed and characterized in order to assess the suitability of these films for biomedical applications. Hence, physicochemical, thermal, barrier and mechanical properties were analyzed and related to the film structure, which showed the prevalence of the triple helix of native collagen after the addition of chitosan....

Collagen obtained from bovine skin was mechanically pre-treated with the aim of preserving the triple helix structure of native collagen. Furthermore, zinc oxide nanoparticles were incorporated into film forming formulations due to their inherent biological properties, which are of great relevance for biomedical applications. All the films showed g...

In this work, bovine collagen was treated with different contents of citric acid and the functional properties of the sheets prepared by compression moulding were investigated. Fourier transform infrared (FTIR) spectroscopy and mechanical properties gave indirect evidence that citric acid-incorporated collagen sheets preserved the triple-helix stru...
