A hybrid scaffold is disclosed which is made of materials that define peripheral layers designed to interface with the tissues in the implant site and one or more intermediate layers. The materials are combined to give the scaffold mechanical properties suitable for withstanding the stresses of the implant site. The materials are fibroin for the peripheral layers and polyurethane combined with fibroin for each intermediate layer.

The disclosure relates to systems and methods for improving the manufacturing of silk solutions and powders containing silk fibroin obtained from silkworm cocoons. The solutions and powders can be used to improve the post-harvest preservation of perishables and to improve the performance of packaging, including biodegradable packaging.

This innovation discloses a bioactive and biocompatible implant that comprises a fibrillar membrane of an electrospun polymeric matrix, where the matrix features a structural reinforcement with gold nanoparticles that allows the propagation of bioelectrical activity of the cardiac tissue, restoring the conductivity of the bioelectrical stimuli, given the electroconductive capacity provided by its components.

The disclosure relates to systems and methods for improving the manufacturing of silk solutions and powders containing silk fibroin obtained from silkworm cocoons. The methods include use of a reactor vessel to degum, rinse, and dissolve the silk fibroin protein from silk inputs to obtain a food grade silk powder. The reactor vessel may include a combination of inputs and outputs for introducing and removing different components used or generated during the process. The systems may include any combination of heat exchangers, holding tanks, filtration modules, and post-treatment equipment as necessary to obtain the silk powder. The solutions and powders can be used to improve the post-harvest preservation of perishables and to improve the performance of packaging, including biodegradable packaging.

An object of the present invention is to provide an artificial fur which has a sufficient moisture-absorbing property and reduces energy required for the manufacture. The artificial fur according to this invention includes an artificial protein fiber.

An object of the present invention is to provide a fabric capable of easily and inexpensively forming a desired three-dimensional shape. The fabric according to the present invention contains an artificial protein fiber that contains a protein, in which the fabric has a surface including: a portion A that shrinks at a predetermined shrinkage rate when being brought into contact with water; and a portion B that has a shrinkage rate lower than that of the portion A when being brought into contact with water.

The present invention relates to a method for manufacturing a protein fiber, including an extension and contraction step of contracting or extending a protein raw fiber containing a protein by bringing the protein raw fiber into contact with a liquid or vapor; and a drying step of drying the protein raw fiber that has undergone the extension and contraction step while adjusting a length of the protein raw fiber to an arbitrary length.

Disclosed is a fiber for artificial hairs that is given a predetermined shape, the fiber being formed from a synthetic fibroin fiber containing a modified fibroin, and the fiber expanding when placed in a wet state and contracting when dried from a wet state. Also disclosed is a method for producing a fiber for artificial hairs that is given a predetermined shape, the method including retaining a fibroin fiber containing a modified fibroin in a state conforming to a predetermined shape. A wetted fibroin fiber may also be heated while being retained in a state conforming to a predetermined shape.

Provided is a side-by-side type composite fiber having a latent crimping ability, including a first component containing a modified fibroin and a second component containing a structural protein, in which the first component and the second component are joined to each other.
