    摘要: An electrosurgical electrospinning device is presented including a reservoir having a polymer solution disposed therein, the reservoir cooperating with a dispensing apparatus configured to dispense the polymer solution from the reservoir. The electrosurgical electrospinning device further includes a plurality of nozzles connected to the reservoir, each nozzle of the plurality of nozzles including a plurality of needles and a blow-spraying mechanism for blowing gas around each nozzle of the plurality of nozzles when the polymer solution is dispensed from the plurality of needles. The gas from the blow-spraying mechanism and the polymer solution from the plurality of needles are coaxially applied directly onto tissue at voltages of less than or equal to 3 kV.

    摘要: Disclosed are methods that utilize the differences in physical properties between two coating fluids to form core-shell particles or core-shell fibers by coaxial free-surface electrospinning. The methods are able to achieve higher productivity than known methods, and are tunable. Nonwoven fiber mats of electrospun fibers have garnered much scientific and commercial interest in recent years due to their unique properties, such as their high porosity, high surface area and small diameter fibers.
