A microfibrillated cellulose-loaded foam is indicated, comprising microfibrillated cellulose, at least one thickening agent and/or at least one adhesive biopolymer. Furthermore, a method for producing such a microfibrillated cellulose-loaded foam and a use of such a foam are provided.

Neurotrophin receptor binding conjugate compositions for delivering an active agent to nerve cells are provided. Conjugate compositions of the present disclosure according to certain embodiments include a one or more active agent compounds (e.g., a dye or small molecule therapeutic) covalently bonded to a protein, peptide or peptidomimetic that binds selectively to a neurotrophin receptor. In embodiments of the compositions, the average ratio of active agent compound to protein, peptide or peptidomimetic in the conjugates is 5 or less. Dual color imaging compositions are also described. Methods for delivering an active agent conjugate selectively into nerve cells (e.g., intraocular delivery) are provided. Also included are methods of making compositions having neurotrophin receptor binding conjugates

A method of producing a fibroin protein product includes providing a stock solution of fibroin protein, injecting a first injection solution including a chaotropic salt into the stock solution, injecting a second injection solution including a kosmotropic salt into the stock solution to provide an intermediate solution, and exposing the intermediate solution to a shear force. A method of preparing a stock solution of fibroin protein includes dissolving a silk fiber into a protic solvent to provide a solution including fibroin protein and adding a chaotropic salt to the solution including fibroin protein to provide the stock solution of fibroin protein. A 3D printer includes a first extruder, a closed duct assembly, at least one injection site, a filter assembly, a printer head assembly, and a printer body.

Silk infused performance apparel and methods of preparing the same are disclosed herein. In some embodiments, silk performance apparel includes textiles, fabrics, consumer products, leather, and other materials that are coated with aqueous solutions of pure silk fibroin-based protein fragments. In some embodiments, coated apparel products, textiles, and upholstery, as well as other materials, exhibit surprisingly improved moisture management properties, resistance to microbial growth, increased abrasion resistance, and flame resistance.

A modified starch exhibits favorable viscosity upon heating and is less likely to decrease in viscosity even by high temperature heating, or has excellent viscosity stability after gelatinization. The modified starch is obtained by preparing a mixture for heat treatment containing starch and a plant-derived dietary fiber or a mushroom-derived dietary fiber and having a specific moisture content, and then dry heating the mixture, wherein the pH at 25° C. when 5 g of the mixture for heat treatment is suspended in 95 ml of water is 5 to 12.

This invention relates generally to water-insoluble but water-swellable and deformable crosslinked PEGylated microgel particles of proteins and protein-based macromolecules that are pseudoplastic (shear thinning) and flow in aqueous media under shear and which can be injected or made to flow, wherein said microgel particles can reform as a cluster of microgel particles when shearing forces are removed. The microgel particles function as a matrix to support cell growth, viability, and proliferation.
