Sustainable Sheep Wool/Soy Protein Biocomposites for Sound Absorption
(MDPI, 2022-12-01)
The wool fibers of the Latxa sheep breed were combined with a soy protein isolate (SPI)
matrix to develop sustainable biocomposites with acoustic properties, adding value to Latxa sheep
wool, which is currently considered ...
New algorithm for the elucidation of functional properties of gelatin-based materials
(Pergamon-Elsevier, 2021-10)
In the present work, fish gelatin was employed to develop renewable and biodegradable materials, reducing environmental problems associated with conventional petroleum-based materials. Glycerol was used as plasticizer and ...
Magnetically responsive chitosan-pectin films incorporating Fe3O4 nanoparticles with enhanced antimicrobial activity.
(Elsevier, 2023-02)
Chitosan-pectin films with iron oxide (Fe3O4) magnetic nanoparticles were prepared by solution casting in order to produce biopolymer based magnetically active materials. Infrared (FTIR) spectra indicated physical interactions ...
Combination of 3D printing and electrospinning to develop chitin/gelatin/PVA scaffolds
(ACC Science, 2023)
In this study, novel scaffolds based on natural polymers were developed by combining 3D printing (3DP) and electrospinning (ES) techniques. ES ink was prepared with gelatin and poly(vinyl alcohol) (PVA), while 3DP ink was ...
Sustainable Collagen Blends with Different Ionic Liquids for Resistive Touch Sensing Applications
(American Chemical Society, 2023-04)
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 ...
The Effect of Cross-Linking with Citric Acid on the Properties of Agar/Fish Gelatin Films
(MDPI, 2020-02-02)
The aim of this work was to assess the effect of fish gelatin–citric acid nucleophilic substitution and agar–citric acid esterification reactions on the properties of agar/fish gelatin films. Since temperature ...
Hybrid 3D Printed and Electrospun Multi-Scale Hierarchical Polycaprolactone Scaffolds to Induce Bone Differentiation
(MDPI, 2022-12-19)
Complex scaffolds composed of micro- and nano-structures are a key target in tissue engineering and the combination of sequential 3D printing and electrospinning enables the fabrication of these multi-scale structures. In ...
3D-Printed Mucoadhesive Collagen Scaffolds as a Local Tetrahydrocurcumin Delivery System
(MDPI, 2021-10-15)
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 ...
Effect of sterilization processes on alginate/gelatin inks for three-dimensional printing
(WHIOCE, 2023)
Sterilization is a crucial step in the process of developing bioinks for tissue engineering applications. In this work, alginate/gelatin inks were subjected to three sterilization methods: ultraviolet (UV) radiation, ...
Electrospinning of Fish Gelatin Solution Containing Citric Acid: An Environmentally Friendly Approach to Prepare Crosslinked Gelatin Fibers
(MDPI, 2019-09-01)
The majority of the crosslinking approaches employed to confer water resistance properties to electrospun gelatin mats are based on the use of potential cytotoxic agents, turning out to be not suitable for biomedical ...
