Yarn and Bundle

Electrospinning may be used to create nanofibrous yarn and bundles. The yarns and bundles may be made out of aligned nanofibers or twisted nanofibers. Nanofibrous bundle may be used as intra-luminal guidance channel in nerve regeneration while continuous nanofibrous yarn may be used to make into textiles.
