The present invention relates to an adhesive and soluble adhesive bandage or patch comprising a soluble film of natural origin with high mineral content. The soluble film comprises from 20 to 90 wt % of mineral filler and wherein the mineral filler content level is higher than the polysaccharide content level. It also relates to these bandages or patches for use in cosmetics or therapy. Also, a method of making a soluble film

A polymer latex including a polymer and at least one polysaccharide selected from the group consisting of tamarind gum, xanthan gum, cationized xanthan gum, gellan gum, guar gum and cationized guar gum.

A functionally gradient material for guided periodontal hard and soft tissue regeneration includes a 3D printed scaffold layer and an electrospun fibrous membrane layer. The content of hydroxyapatite in the 3D printed scaffold layer is higher than the content of hydroxyapatite in the electrospun fibrous membrane layer. The pore size of the 3D printed scaffold layer is larger than the pore size of the electrospun fibrous membrane layer. The pore size of the 3D printed scaffold layer is 100-1000 μm, and the fiber diameter of the electrospun fibrous membrane layer is 300-5000 nm. The electrospun fibrous membrane layer is in a random distribution or an oriented arrangement or has a mesh structure. The thickness of the electrospun fibrous membrane layer is 0.08-1 mm.

A natural composition for 3D printing comprising alginate from brown seaweed and cellulose nanofibers, wherein the cellulose nanofibers originate from cellulose from the same brown seaweed sample(s) as the alginate.

The present invention relates to a hydrogel comprising an oxidized alginate containing aldehyde groups, wherein the oxidized alginate is crosslinked with an imine type crosslinker. The hydrogel is particularly suitable as a bioink, i.e. for 3D printing of cell structures. The gels provide good printability and exhibit excellent viscoelasticity, shear thinning and self-healing characteristics.

System and method of bioprinting used to enable automated fabrication of various constructs with high reproducibility and scalability, while reducing costs and production timelines. The bioprinting applications provides a critical component to the further enrichment the overall biomanufacturing paradigm. The biofabrication of sheet-like implantable constructs and other construct types with cells deposited on both sides—a process that may be both scaffold and cell type agnostic, and furthermore, is amenable to many additional tissue engineering applications beyond skeletal muscle.

A method for forming a chitin film is provided. The method includes the following steps. In a step (a), a chitin suspension is prepared by adding chitin to water. In a step (b), physical forces are provided to process the chitin suspension, so that a mean particle diameter of the chitin is reduced. In a step (c), the chitin suspension is applied to a target, and the chitin film is formed after the chitin suspension is dried.

A 3D (three dimensional) Bioprinter that uses plant stem cells applied to the recreation of skin tissue for facial rejuvenation, in addition to the facial biomask produced from the 3D bioprinter. The field of application of this utility model patent application is related to the Esthetics and Cosmetology industries. 3D bioprinting with plant stem cells is the latest and most revolutionary treatment for the prevention of aging and facial rejuvenation. It is a one hundred percent natural protocol for recreating the beauty of human skin.

The present invention relates to a fishing bait, a mouldable composition for manufacturing the fishing bait, a method for manufacturing the fishing bait and a use of the mouldable composition. The mouldable composition comprises a basic solution comprising water, a gelling agent and a plasticizer. The mouldable composition further comprises at least one cross-linking agent in the volume of the basic solution.
