A fiber may comprise an electrospun polymer and a contrast agent. 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 contrast agent. |
