Abstract
With its very high theoretical energy density, the Li-O2 battery could be considered a valid candidate for future advanced energy storage solutions. However, the challenges hindering the practical application of this technology are many, as for example electrolyte degradation under the action of superoxide radicals produced upon cycling. In that frame, a gel polymer electrolyte was developed starting from waste-derived components: gelatin from cold water fish skin, waste from the fishing industry, and wood flour waste from the wood industry. Both were methacrylated and then easily cross-linked through a one-pot ultraviolet (UV)-initiated free radical polymerization, directly in the presence of the liquid electrolyte (0.5 M LiTFSI in DMSO). The wood flour works as cross-linking points, reinforcing the mechanical properties of the obtained gel polymer electrolyte, but it also increases Li-ion transport properties with an ionic conductivity of 3.3 mS cm-1 and a transference number of 0.65 at room temperature. The Li-O2 cells assembled with this green gel polymer electrolyte were able to perform 180 cycles at 0.1 mA cm-2, at a fixed capacity of 0.2 mAh cm-2, under a constant O2 flow. Cathodes post-mortem analysis confirmed that this electrolyte was able to slow down solvent degradation, but it also revealed that the higher reversibility of the cells could be explained by the formation of Li2O2 in the amorphous phase for a higher number of cycles compared to a purely gelatin-based electrolyte.

Abstract
The production of customized polymeric hydrogels in the form of 3D scaffolds with application in bone tissue engineering is currently a topic of great interest. Based on gelatin methacryloyl (GelMa) as one of the most popular used biomaterials, GelMa with two different methacryloylation degrees (DM) was obtained, to achieve crosslinked polymer networks by photoinitiated radical polymerization. In this work, we present the obtention of new 3D foamed scaffolds based on ternary copolymers of GelMa with vinylpyrrolidone (VP) and 2-hydroxyethylmethacrylate (HEMA). All biopolymers obtained in this work were characterized by infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA), whose results confirm the presence of all copolymers in the crosslinked biomaterial. In addition, scanning electron microscopy (SEM) pictures were obtained verifying the presence of the porosity created by freeze-drying process. In addition, the variation in its swelling degree and its enzymatic degradation in vitro was analyzed as a function of the different copolymers obtained. This has allowed us to observe good control of the variation in these properties described above in a simple way by varying the composition of the different comonomers used. Finally, with these concepts in mind, biopolymers obtained were tested through assessment of several biological parameters such as cell viability and differentiation with MC3T3-E1 pre-osteoblastic cell line. Results obtained show that these biopolymers maintain good results in terms of cell viability and differentiation, along with tunable properties in terms of hydrophilic character, mechanical properties and enzymatic degradation.

Abstract
The combination of desirable polymer properties and methods for synthesis, utilizing materials with various architectures, could be adopted for diverse clinical applications such as wound healing as well as stem cell differentiation. Natural polymers, particularly polysaccharides, are biocompatible and are reported to have structural similarities with extracellular matrix components. In this scenario, the present study fabricated a porous scaffold using a polysaccharide, galactoxyloglucan, isolated from Tamarind seed kernel, and studied its applications in stem cell attachment and wound healing. In-growth of human mesenchymal stem cells (hMSCs) presented a rounded morphology with increased proliferation. Scaffolds were surface-functionalized with silver nanoparticles to increase the antibacterial activity and the wound healing potential evaluated in preclinical mouse models. The current study provides an insight into how stem cells attach and grow in a naturally derived low-cost polysaccharide scaffold with antibacterial, biocompatible, and biodegradable properties.

Abstract
Irrespective of the labyrinth of fastidiously woven artificial scaffolds, the lack of biocompatibility hampers effective clinical translation, which is the definitive purpose of any biomedical system or device. Hence, the current exploration deals with the fabrication of scaffolds with enhanced bioactivities for wound healing. The methodology used for the fabrication of the scaffolds was electrospinning of the polysaccharide, which is isolated from tamarind seed kernel using the electrospinning process. To improve the antimicrobial activity of the scaffolds, in-house synthesized silver nanoparticles were added to the scaffolds. Wound healing and antimicrobial efficiency of the scaffolds were established in murine models. An insight into the wound healing mechanism was also analyzed using differentiation screening of stem cells grown on scaffolds. The results showed that newly synthesized scaffolds presented excellent wound healing ability along with antimicrobial activity. Furthermore, detailed toxicological evaluations through the histopathology and collagen staining wound sections, the probability of any off-target effects were also ruled out. Differentiation screening showed that adipogenesis was more prominent in cells attached to the scaffolds and markers of adipogenesis were strongly expressed in fluorescent microscopy. Thus we hope that the scaffolds mediate stem cell differentiation in wounds and promote a progressive healing response. Results thus obtained were encouraging and further studies need to embark on to establish the combined role in all aspects studied here.

Porous scaffolds with the structure of an interpenetrating polymer network made by gelatin methacrylated nanoparticle-stabilized high internal phase emulsion polymerization targeted for tissue engineering. RSC Adv 2021; 11:22544-22555.

Abstract
The interlacing of biopolymers and synthetic polymers is a promising strategy to fabricate hydrogel-based tissue scaffolds to biomimic a natural extracellular matrix for cell growth. Herein, open-cellular macroporous 3D scaffolds with a semi-interpenetrating network were fabricated through high internal phase emulsion templating. The scaffolds are prepared by (I) the curing of PEG diacrylate (PEGDAC) and gelatin methacrylate (GelMA) in the continuous aquatic phase of a coconut oil-in-water emulsion stabilized by GelMA nanoparticles, and (II) the removal of the internal phase. The effect of the main contributing parameters such as pH, GelMA content, and GelMA/PEGDAC weight ratio on the emulsion features was investigated systematically. Due to the isoelectric point of GelMA at around pH 6, the GelMA particle (aggregation) size decreased at both sides of pH from 1000 to 100–140 nm because of the increased number of positive and negative charges on GelMA. These GelMA nanoparticles were able to produce stable emulsions with narrowly distributed small emulsion droplets. Moreover, the stability and emulsion droplet size were enhanced and increased, respectively, with GelMA content increasing and GelMA/PEGDAC weight ratio decreasing. These trends lie in the prevented coalescence phenomenon caused by the improved viscosity and likely partially formed network by GelMA chains in the continuous phase. Hence, the following formulation was selected for scaffold preparation: φoil = 74%, pH = 12, GeMA = 4 wt%, and GelMA/PEGDAC = 10/8. Then, PCL in different contents was infiltrated into the scaffold to balance hydrophilicity and hydrophobicity. The cell culture assay proved that the scaffold with a pore size of 60–180 μm and containing 51.2 wt% GelMA, 10.3 wt% PEG, and PCL 27.2 wt% provided a suitable microenvironment for mouse fibroblast cell (L929) adhesion, growth, and spreading. These results show that this strategy suggests promising culture for tissue engineering applications. The interlacing of biopolymers and synthetic polymers is a promising strategy to fabricate hydrogel-based tissue scaffolds to biomimic a natural extracellular matrix for cell growth.![]()

Abstract
The development of new biomaterial inks with good structural formability and mechanical strength is critical to the fabrication of 3D tissue engineering scaffolds. For extrusion-based 3D printing, the resulting 3D constructs are essentially a sequential assembly of 1D filaments into 3D constructs. Inspired by this process, this paper reports the recent study on 3D printing of nanoclay-incorporated double-network (NIDN) hydrogels for the fabrication of 1D filaments and 3D constructs without extra assistance of support bath. The frequently used "house-of-cards" architectures formed by nanoclay are disintegrated in the NIDN hydrogels. However, nanoclay can act as physical crosslinkers to interact with polymer chains of methacrylated hyaluronic acid (HAMA) and alginate (Alg), which endows the hydrogel precursors with good structural formability. Various straight filaments, spring-like loops, and complex 3D constructs with high shape-fidelity and good mechanical strength are fabricated successfully. In addition, the NIDN hydrogel system can easily be transformed into a new type of magnetic responsive hydrogel used for 3D printing. The NIDN hydrogels also supported the growth of bone marrow mesenchymal stem cells and displayed potential calvarial defect repair functions.

Abstract
Bioink with inherent antibacterial activity is of particular interest for tissue engineering application due to the growing number of bacterial infections associated with impaired wound healing or bone implants. However, the development of cell-laden bioink with potent antibacterial activity while supporting tissue regeneration proved to be challenging. Here, we introduced a cell-laden antibacterial bioink based on Methylcellulose/Alginate (MC/Alg) hydrogel for skin tissue engineering via elimination of the risks associated with a bacterial infection. The key feature of the bioink is the use of gallium (Ga+3) in the design of bioink formulation with dual functions. First, Ga+3 stabilized the hydrogel bioink by the formation of ionic crosslinking with Alg chains. Second, the gallium-crosslinked bioink exhibited potent antibacterial activity toward both Gram-positive (Staphylococcus aureus) and Gram-negative (Pseudomonas aeruginosa) bacteria with a bactericidal rate of 99.99 %. In addition, it was found that the developed bioink supported encapsulated fibroblast cellular functions.

Abstract
Fabrication of simultaneously robust and superabsorbent gelatin-based hydrogels for biomedical applications still remains a challenge due to lack of locally dissipative points in the presence of large water content. Here, we apply a synthesis strategy through which water absorbency and energy dissipative points are separated, and toughening mechanism is active closely at the crack tip. For this, gelatin-based microgels (GeMs) were synthesized in a way that concentrated supramolecular interactions were present to increase the energy necessary to propagate a macroscopic crack. The microgels were interlocked to each other via both temporary hydrophobic associations and permanent covalent crosslinks, in which the sacrificial binds sustained the toughness due to the mobility of the junction zones and particles sliding. However, chemical crosslinking points preserved the integrity and fast recoverability of the hydrogel. Hysteresis increased strongly with increasing supramolecular interactions within the network. The prepared hydrogels showed energy loss and swelling ratio up to 3440 J. m-3 and 830%, respectively, which was not achievable with conventional network fabrication methods. The microgels were also assessed for their in vivo biocompatibility in a rat subcutaneous pocket assay. Results of hematoxylin and eosin (H&E) staining demonstrated regeneration of the tissue around the scaffolds without incorporation of growth factors. Also, vascularization within the scaffolds was observed after 4 weeks implantation. These results indicate that our strategy is a promising method to manipulate those valuable polymers, which lose their toughness and applicability with increasing their water content.

Abstract
Bone repair is a complex process involving the sophisticated interplay of osteogenic stem cells, extracellular matrix, and osteoinductive factors, and it is affected by bacterial toxins and oxidative stress. Inspired by the nature of plant-derived phytochemicals and inorganic-organic analogues of the bone extracellular matrix, we report herein the facile design of a nanoclay-organic hydrogel bone sealant (NoBS) that integrates multiple physico-chemical cues for bone regeneration into a single system. Assembly of phytochemical-modified organic chitosan and silica-rich inorganic nanoclay serves as highly biocompatible and osteoconductive extracellular matrix mimics. The decorated phytochemical exerts inherent bactericidal and antioxidant activities, and acts as an intermolecular networking precursor for gelation with injectable and self-healing capabilities. Moreover, the NoBS exerts osteoinductive effects mediated by the nanoclay, which regulates the Wnt/β-catenin pathway, along with the addition of osteoinductive signals, resulting in bone regeneration in a non-healing cranial defect. Engineering of this integrated bone graft substitute with multifunctional properties inspired by natural materials may suggest a promising and effective approach for creating a favorable microenvironment for optimal bone healing.

Abstract
The extensive advancement with novel wound dressing materials functionalized with desirable properties, often touted as a panacea for cuts and burns afflicting various pathologies. However, it would indeed be a hard task to isolate any such material which perfectly fits the needs of any biomedical issue at hand. Biocompatibility, biodegradability as well as non-toxicity of natural polysaccharide served as a versatile and tunable platform for designing natural polysaccharide based scaffolds as an attractive tool in tissue engineering with a greater degree of acceptability. In this regard, we aimed to fabricate a semi interpenetrating hydrogel via exploiting the nontoxic and immune-stimulatory nature of galacto-xyloglucan (PST001) which was further doped with silver nanoparticles to formulate SNP@PST. The wound healing potential of SNP@PST was then studied both with in vitro and preclinical mice models. The current study gives a formulation for cost effective preparation of polysaccharide hydrogels using acrylamide crosslinking with improved biocompatibility and degradability. Wound healing studies in mice proved the efficiency of gels for the clinical application wherein the incorporation of nanosilver greatly enhanced the antimicrobial activity.

Abstract
For diseases related to genetic disorders or cancer, many cellular therapies rely on the ex vivo modification of cells for attaining a desired therapeutic effect. The efficacy of such therapies involving the genetic modification of cells relies on the extent of gene expression and subsequent persistence of modified cells when infused into the patient's body. In situ gene delivery implies the manipulation of cells in their in vivo niche such that the effectiveness can be improved by minimizing post manipulation effects like cell death, lack of persistence, etc. Furthermore, material-based in situ localized gene delivery can reduce the undesired side effects caused by systemic modifications. Here, we have used polyethylene (glycol) diacrylate (PEGDA) based cryogels to genetically modify cells in vivo with a focus on immunotherapy. PEGDA cryogels were either blended with gelatin methacrylate (GELMA) or surface modified with poly-l-lysine (PLL) in order to improve cell adhesion and/or retain viruses for localized gene delivery. On using the lentiviruses encoding gene for green fluorescent protein (GFP) in in vitro experiments, we found higher transduction efficiency in HEK 293FT cells via PEGDA modified with poly-l-lysine (PEGDA-PLL) and PEGDA-GELMA cryogels compared to PEGDA cryogels. In vitro release experiments showed improved retention of GFP lentiviruses in PEGDA-PLL cryogels, which were then employed for in vivo gene delivery and were demonstrated to perform better than the corresponding bolus delivery of lentiviruses through an injection. Both physical and biological characterization studies of these cryogels show that this material platform can be used for gene delivery as well as other tissue engineering applications.

Abstract
The formation of complete and well-functioning endothelium is critical for the success of tissue-engineered vascular grafts yet remaining a fundamental challenge. Endothelium remodeling onto the lumen of tissue-engineered vascular grafts is affected by their topographical, mechanical, and biochemical characteristics. For meeting multiple requirements, composite strategies have recently emerged for fabricating hybrid scaffolds, where the integrated properties are tuned by varying their compositions. However, the underlying principle how the integrated properties of hybrid scaffolds regulate vascular endothelium remodeling remains unclear. To uncover the regulation effects of hybrid scaffolds on vascular endothelium remodeling, we prepared different biomimetic hybrid scaffolds using gelatin methacrylamide (GelMA) and poly-ε-caprolactone (PCL) and then investigated vascular endothelial cell responses on them. GelMA and PCL, respectively, conferred the resulting scaffolds with biomimetic bioactivity and mechanical properties, which were tuned by varying GelMA/PCL mass ratios (3:1, 1:1, or 1:3). On different GelMA/PCL hybrid scaffolds, distinct vascular endothelial cell responses were observed. Firm cell-scaffold/cell-cell interactions were rapidly established on the hybrid scaffolds with the highest mass ratio of bioactive GelMA. However, they were mechanically insufficient as vascular grafts. On the contrary, the scaffolds with the highest mass ratio of PCL showed significantly reinforced mechanical properties but poor biological performance. Between the two extremes, the scaffolds with the same GelMA/PCL mass ratio balanced the pros and cons of two materials. Therefore, they could meet the mechanical requirements of vascular grafts and support the early-stage vascular endothelial cell remodeling by appropriate biological signaling and mechanotransduction. This investigation experimentally proves that scaffold bioactivity is the dominant factor affecting vascular endothelial cell adhesion and remodeling, whereas mechanical properties are crucial factors for the integrity of endothelium. This work offers a universal design strategy for desirable vascular grafts for improved endothelium remodeling.

Coaxial electrospun PCL/Gelatin-MA fibers as scaffolds for vascular tissue engineering. Colloids Surf B Biointerfaces 2017; 159:7-15.

Abstract
Coaxial electrospinning is a technique that allows the production of nanofibers with a core-shell structure. Such fibers present several advantages as materials for the preparation of scaffolds, namely due to the possibility of combining a core with the desired mechanical properties with a shell prepared from biocompatible materials that will establish proper interactions with the host. Herein, core-shell fibrous meshes, composed of a polycaprolactone (PCL) core and a functionalized gelatin shell, were prepared by coaxial electrospinning and then photocrosslinked under UV light aiming to be used in vascular tissue regeneration. The suitability of the meshes for the pretended biomedical application was evaluated by assessing their chemical/physical properties as well as their haemo and biocompatibility in vitro. The obtained results revealed that meshes' shell prepared with a higher content of gelatin showed fibers with diameters presenting a unimodal distribution and a mean value of 600nm. Moreover, those fibers with higher content of gelatin also displayed lower water contact angles, and therefore higher hydrophilicities. Such features are crucial for the good biologic performance displayed by these meshes, when in contact with blood and with Normal Human Dermal Fibroblasts cells.
