US Patent 7537807 - Electrospray nanofiber deposition

This patent from Cornell University teaches a new type of deposition technique for polymeric nanofibers using a microfluidic emitter tip. Claim 1 reads:

1. A method of forming nanofibers, the method comprising:

positioning a target substrate and counter electrode a desired distance from a microfluidic emitter having an emitter tip;

providing a polymer to the microfluidic emitter tip;

applying a potential between the microfluidic emitter tip and the target substrate to create nanofibers on the target substrate and;

creating lateral movement between the target substrate and the microfluidic emitter.
