The present invention relates to electrospun fibers comprising i) a hydrophilic polymer that is soluble in a first solvent, ii) a bioadhesive substance that is slightly soluble in said first solvent, iii) optionally, a drug substance.

Wicking materials are described comprising: a first layer comprising a plurality of cellulose acetate (CA) fibers; and a second layer comprising a plurality of polyvinylpyrrolidone (PVP) fibers. Methods of manufacturing the wicking materials and biosensors comprising the same are also described.

A method of making a ceramic fiber tow and the system regarding the same may be included. The method may include commingling a plurality of ceramic fibers with a fugitive fiber to form a single ceramic fiber tow. The fugitive fiber may be positioned between at least two ceramic fibers included in the single ceramic fiber tow. The method may further include forming a porous ceramic preform including at least the single ceramic fiber tow. The method may further include removing the fugitive fiber from the ceramic fiber tow leaving a space between at least two ceramic fibers of the single ceramic fiber tow. The method may further include replacing the spaces between ceramic fibers included in the ceramic fiber tows with a ceramic matrix.

A method for making electrically-conductive yarn includes simultaneously drawing and axially twisting a starting material selected from a group consisting of intrinsically electrically-conducting fiber nonwovens and multifilament tows of intrinsically electrically-conducting fiber. The resulting yarn is a compacted, intrinsically electrically-conducting fiber material having an axial twist of between about 0.5 and about 60 degrees.

The invention relates to bone repair and more specifically to a berberine/mineralized collagen-based composite membrane, a preparation method, and an application thereof. The composite membrane includes a berberine nanofiber membrane and a mineralized collagen membrane disposed on a unilateral surface of the berberine nanofiber membrane. The mineralized collagen with biomimetic mineralization capacity is combined with a Chinese materia medica monomer, berberine, the resulting bilayer composite membrane has a better effect on promoting osteogenesis In addition, a novel dosage form of berberine is constructed. An electrospinning method prepares a berberine nanofiber membrane. The berberine nanofibers are received by the mineralized collagen membrane, or after the berberine nanofiber membrane is obtained, a mineralized collagen membrane is prepared by applying on the surface of the berberine nanofiber membrane.

Spacers for filtration applications are provided. A spacer for a filtration device comprises a substrate comprising a cyclic polyolefin. The substrate comprises a plurality of through-holes for filtering particles having an average particle size of greater than 50 ?m. Filtration assemblies, filtration devices, and related systems and methods are also provided.

The present invention relates to electrospun fibers comprising i) a hydrophilic polymer that is soluble in a first solvent, ii) a bioadhesive substance that is slightly soluble in said first solvent, iii) optionally, a drug substance.
