Cytocompatibility and Suitability of Protein-Based Biomaterials as Potential Candidates for Corneal Tissue Engineering
(MDPI, 2021-03-31)
The vision impairments suffered by millions of people worldwide and the shortage of corneal donors show the need of substitutes that mimic native tissue to promote cell growth and subsequent tissue regeneration. The current ...
Polyhydroxybutyrate (PHB) produced from red grape pomace: Effect of purification processes on structural, thermal and antioxidant properties.
(Elsevier, 2022-09)
Red grape pomace was used as a source for poly(3-hydroxybutyrate) (PHB) production, which was then subject to a range of purification processes. The different PHB biopolymers were characterized for chemical structure, ...
Tailoring physicochemical properties of collagen-based composites with ionic liquids and wool for advanced applications
(Elsevier, 2022-06)
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 molding. Scanning electron ...
Plasma-Based Bioinks for Extrusion Bioprinting of Advanced Dressings
(2021-08-16)
Extrusion bioprinting based on the development of novel bioinks offers the possibility of manufacturing clinically useful tools for wound management. In this study, we show the rheological properties and printability ...
3D Printed Chitosan-Pectin Hydrogels: From Rheological Characterization to Scaffold Development and Assessment
(MDPI, 2021-10-21)
Chitosan-pectin hydrogels were prepared, and their rheological properties were assessed in order to select the best system to develop scaffolds by 3D printing. Hydrogels showed a weak gel behavior with shear thinning flow ...
Effect of gelatin concentration, ribose and glycerol additions on the electrospinning process and physicochemical properties of gelatin nanofibers
(Elsevier, 2022-11)
Rheological properties of gelatin-based solutions containing different concentrations of ribose and/or glycerol were assessed before electrospun mats were manufactured and their properties investigated. Characterization ...
Physicochemical and Biological Performance of Aloe Vera-Incorporated Native Collagen Films
(MDPI, 2020-12-02)
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 ...
A Green Approach towards Native Collagen Scaffolds: Environmental and Physicochemical Assessment
(MDPI, 2020-07-18)
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 ...
Evaluation of Bioactive Release Kinetics from Crosslinked Chitosan Films with Aloe Vera
(Elsevier, 2021-07-01)
Thermocompression was employed to prepare citric acid-crosslinked chitosan films with Aloe vera (AV) as bioactive compound. Films were easy to handle and mechanical properties did not change with the addition of AV up to ...
Chitosan Films Incorporated with Exopolysaccharides from Deep Seawater Alteromonas sp.
(MDPI, 2020-08-27)
Two Alteromonas sp. strains isolated from deep seawater were grown to promote the production of exopolysaccharides (EPS, E611 and E805), which were incorporated into chitosan solutions to develop films. The combination of ...
