NANOFIBER SURFACES FOR USE IN ENHANCED SURFACE AREA APPLICATIONS

摘要

The invention pertains to the field of nanofibers, and provides novel nanofiber structures having enhanced surface areas for increased functionality. In particular, a drug delivery device is provided for introduction of one or more substances into a subject, which device comprises a substrate made from a first material, which substrate comprises: at least a first surface, a plurality of semiconductor nanofibers attached to the first surface which nanofibers are made from a second compositionally different material from the first material, and a reservoir of the one or more substances comprised between the members of the plurality of nanofibers. The one or more substances is incorporated into the reservoir such that said one or more substances is at least partially shielded from direct exposure to bodily fluids within the subject when the device is introduced into the subject.
