Abrégé
(EN)

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.
