摘要： The present invention refers to a composition comprising a solution which in turn comprises an amino acidic chain gelatin polymer derived from natural sources of cold-adapted marine species, at a concentration from 1% to 20% (w/v), which optionally further comprises a polymerizing initiator such as a photoinitiator, and is chemically functionalized to become reactive to polymerization or crosslinking in presence of free radicals. This composition is especially useful for 3D printing, extrusion systems (additive fabrication), spray systems, casting, micro- and nano fibers fabrication systems (electrospinning, solution blow spinning) or microfluidics.

摘要： The invention provides injectable, tough hydrogels that can be crosslinked in situ on demand using minimally-invasive methods, such as visible light exposure is an unmet medical challenge. Among the emerging biopolymers for tissue sealing, gelatin methacryloyl (GelMA), a naturally-derived biopolymer obtained from denatured collagen, has secured a promising role as a result of its excellent bioadhesion, biodegradation, and biocompatibility. To overcome one of the main shortcomings of GelMA, i.e., brittleness, we hybridized it using methacrylate-modified alginate (AlgMA) to impart ion-induced reversible crosslinking that can dissipate energy under strain. The hybrid GelMA-AlgMA hydrogels provide a photocrosslinkable, injectable, and adhesive platform with an excellent toughness that can be engineered using divalent cations, such as calcium. This class of novel hybrid biopolymers with more than 600% improved toughness may set the stage for durable, mechanically-resilient, and cost-effective tissue sealants in minimally invasive procedure, especially for stretchable tissues.

摘要： A method of preparing a vinyl collagen microsphere polyamide fiber composite material includes the following steps: step 1: modifying a collagen with methacrylic anhydride to obtain a vinyl collagen, then emulsifying and cross-linking the vinyl collagen to obtain vinyl collagen microspheres; step 2: treating a polyamide fiber substrate with formaldehyde to obtain a hydroxylated polyamide fiber substrate, treating the hydroxylated polyamide fiber with (3-mercaptopropyl)trimethoxysilane (MPS) to obtain a sulfhydrylated polyamide fiber substrate; and step 3: modifying the sulfhydrylated polyamide fiber substrate with the vinyl collagen microspheres to obtain the vinyl collagen microsphere polyamide fiber composite material.

摘要： This invention includes malleable, biodegradable, fibrous compositions for application to a tissue site in order to promote or facilitate new tissue growth. One aspect of this invention is a fibrous component that provides unique mechanical and physical properties. The invention may be created by providing a vessel containing a slurry, said slurry comprising a plurality of natural or synthetic polymer fibers and at least one suspension fluid, wherein the polymer fibers are substantially evenly dispersed and randomly oriented throughout the volume of the suspension fluid; applying a force, e.g., centrifugal, to said vessel containing said slurry, whereupon said force serves to cause said polymer fibers to migrate through the suspension fluid and amass at a furthest extent of the vessel, forming a polymer material, with said polymer material comprising polymer fibers of sufficient length and sufficiently viscous, interlaced, or interlocked to retard dissociation of said polymer fibers.
