Beschreibung
Zusammenfassung:	Nanofiber electroprocessing apparatus comprising a conductive stylus having a 5 to 250 nm diameter tip; a collector spaced below the tip; a continuous supply of flowable polymer to the tip, and a power supply for creating a potential difference between the tip and the collector sufficient to produce a nanofiber. The conductive stylus may comprise an atomic force microscope (AFM) tip and may further be mounted within an AFM scanning holder having a mechanism for moving the tip. A method of electroprocessing a nanofiber comprises providing the conductive stylus, such as an AFM tip, providing a collector below the tip, supplying the tip with the flowable polymer, energizing the tip to create a potential difference between the tip and the collector, and thereby producing the nanofiber. Systems and methods for using nanofibers so created may be used for anticounterfeiting or object identification.
