Nanofibrous materials as drug, protein, or genetic release vehicles

An electrospinning perfusion method for forming a fabricated textile comprising nanofibers suitable for use as a medical article, the method comprising steps of:

• dissolving 19-20% weight per volume of a non-biodegradable polymer and a biologically-active agent in an organic solvent to provide an admixture, the dissolving step occurring at an ice-cold temperature of about 4° C., wherein the non-biodegradable polymer is not polytetrafluoroethylene, polypropylene, or polyethylene;
• loading the admixture into an electrospinning perfusion instrument which can be set at a specified flow rate;
• applying an electric current of 15-20 kV to a needle of the electrospinning perfusion instrument;
• perfusing the admixture onto a target surface at the specified flow rate, the perfusion process occurring at a temperature of about 25° C. to provide a perfused nanofibers, each having a diameter from 100 nm to 3000 nm;
• and
• permitting trace solvent to be removed from the perfused nanofibers to form a biologically-active fabricated textile.
