Abstract

See full text

Provided herein are apparatus and systems for fabricating highly aligned arrays of polymeric fibers having isodiameters ranging from sub 50 nm to microns with lengths of several millimeters. The approach disclosed herein uses (e.g.) a micropipette to deliver polymeric solution which is collected in the form of aligned fibers on a rotating and linearly translating substrate. The methods deposit polymeric fibers on spherical surfaces and gapped surfaces with precise control, thus heralding new opportunities for a variety of applications employing polymeric fibers. The design workspace for depositing fibers disclosed herein is dependent upon processing parameters of rotational/linear translational speeds and material properties of solution rheologies. Techniques for fabrication of multilayer fiber arrays, for fabrication of cell growth scaffolds and for attachment of particles to the fiber arrays are also disclosed.
