ELECTROSPUN FIBERS HAVING A PHARMACEUTICAL AND METHODS OF MAKING AND USING THE SAME
A fiber may comprise an electrospun polymer and a pharmaceutical. The pharmaceutical may be dispersed within the electrospun polymer, and may have the form of a crystal, an oil, or a combination thereof. A method of making an electrospun fiber may comprise configuring a receiving surface to receive a polymer fiber, applying a charge to one or more of the receiving surface, a polymer injection system, and a polymer solution ejected from the polymer injection system, and depositing a polymer solution ejected from the polymer injection system onto the receiving surface. The polymer solution may comprise a polymer and a pharmaceutical. A method of treating a disorder in a subject may comprise obtaining such a fiber having an effective amount of a pharmaceutical, applying the fiber to an oral region of the subject, and allowing the fiber to disintegrate, thereby delivering the effective amount of the pharmaceutical to the subject.
Method for preparing electro-mechanically stretched hydrogel micro fibers
The presently disclosed subject matter provides a scalable and electrostretching approach for generating microfibers exhibiting uniaxial alignment from polymer solutions. Such microfibers can be generated from a variety of natural polymers or synthetic polymers. The hydrogel microfibers can be used for controlled release of bioactive agents.
