摘要： The invention relates to a novel method for electrospinning fibers wherein the fiber-spinning solution is infused with gas bubbles which travel through the electrospinning fluid, causing the bubbles to be coated with electrospinning solution. The coated bubbles, in turn, in response to an applied electrical force, generate jets of the electrospinning fluid that travel away from the bubble surface. The invention further relates to the fibers formed by this bubble-jet process and to products made therefrom.

摘要： A nanofiber-reinforced composition suited to applying to a wound site in a human body includes a carrier liquid and nanofibers dispersed therein in the carrier liquid. The viscosity of the composition is such that it is able to be applied through a tube yet adhere proximate the wound site to provide a barrier layer which assists in healing of the wound by spacing it from neighboring organs.

摘要： A novel coating for medical devices provides nitric oxide delivery using nanofibers of linear poly(ethylenimine)diazeniumdiolate. Linear poly(ethylenimine)diazeniumdiolate releases nitric oxide (NO) in a controlled manner to tissues and organs to aid the healing process and to prevent injury to tissues at risk of injury. Electrospun nano-fibers of linear poly(ethylenimine) diazeniumdiolate deliver therapeutic levels of NO to the tissues surrounding a medical device while minimizing the alteration of the properties of the device. A nanofiber coating, because of the small size and large surface area per unit mass of the nanofibers, provides a much larger surface area per unit mass while minimizing changes in other properties of the device.

摘要： A process for forming nanofibers comprising the steps of feeding a fiber-forming material into an annular column, the column having an exit orifice, directing the fiber-forming material into an gas jet space, thereby forming an annular film of fiber-forming material, the annular film having an inner circumference, simultaneously forcing gas through a gas column, which is concentrically positioned within the annular column, and into the gas jet space, thereby causing the gas to contact the inner circumference of the annular film, and ejects the fiber-forming material from the exit orifice of the annular column in the form of a plurality of strands of fiber-forming material that solidify and form nanofibers having a diameter up to about 3,000 nanometers.
