In one example, nanofiber based micro-structured material is used as an electrode in a battery, such as a lithium ion battery, where the nanofibers of micro-structured material form a nanofiber cloth with free-standing, core-shell structure.

An applicator is disclosed for applying a treatment solution to a treatment site of a patient. The applicator can include an applicator housing comprising a treatment solution reservoir. A cartridge can be removably disposed in the housing. The cartridge when arranged in the housing can be in fluid communication with the treatment solution reservoir. The cartridge can include an electrostatic module for electrostatically charging the treatment solution in the treatment solution reservoir; and a nozzle for applying the treatment solution.

As described below, the present invention features compositions and methods for inhibiting inflammation in connection with an acellular template (e.g., an electrospun template). In one embodiment, the template is impregnated with an agent (e.g., N-α-benzoyl-N5-(2-chloro-1-iminoethyl)-L-ornithine amide (Cl-amidine)) that inhibits a peptidylarginine deaminase (e.g., PAD4).

There is provided a liquid filter having a small pressure loss and a manufacturing method for a liquid filter. The liquid filter is a liquid filter that is composed of a nonwoven fabric formed of fibers containing a water-insoluble polymer and a hydrophilizing agent. In the nonwoven fabric, a fiber density continuously changes in a film thickness direction, a fiber density difference is present in the film thickness direction, the fiber density of one surface of the nonwoven fabric in the film thickness direction is maximal, and the fiber density of the other surface of the nonwoven fabric in the film thickness direction is minimal.

A biodegradable and biocompatible barrier membrane of piezoelectric nano composites of Metallic Oxide (MO) (e.g., Magnesium oxide, Zinc oxide and iron oxide)-PLLA (Poly-L-lactide), which can be subjected to acoustic pressure from ultrasound, to generate useful electrical charge for enhanced bone regeneration and enhanced antibacterial effects for guided bone regeneration to treat dental diseases, such as periodontitis.

A composite electrode includes two or more types of fibers forming a fiber network, comprising at least a first type of fibers and a second type of fibers. The first type of fibers comprises a first polymer and a first type of particles. The second type of fibers comprises a second polymer and a second type of particles. The second polymer is same as or different from the first polymer. The second type of particles are same as or different from the first type of particles.

Disclosed herein is a particle delivery system comprising electrospun nanofiber comprised of coaxial fiber with a microfluidic core. Iron-doped apatite nanoparticles (IDANPs) have demonstrated a unique influence over phage killing of bacteria, whereby, IDANP-exposed bacterial cultures experience 2× the bacterial death as controls. IDANPs consist of hydroxyapatite (HA) doped with iron. HA is a mineral known to be biocompatible and analogous to the inorganic constituent of mammalian bone and teeth and has been approved by the Food and Drug Administration (FDA) for many applications in medicine and dentistry. Previous work has shown that for IDANPs to enhance antibacterial activity of phage to the greatest extent, bacterial cultures should be exposed to IDANPs for 1 hr prior to phage introduction. Biocompatible polymer materials which encase IDANPs and/or phage can be used to disseminate IDANPs and/or phage in a controlled manner into a physiological system for treatment of bacterial infection. When components of said materials contain micro- or nano-scale components, high surface-to-volume ratio for treatment delivery is garnered.
