Fig. 2From: Preparation of bilayer tissue-engineered polyurethane/poly-L-lactic acid nerve conduits and their in vitro characterization for use in peripheral nerve regenerationMacrographs of nanofibrous nerve construct. a-d Bilayer nanofibre nerve conduit; (e, f) scanning electron micrographs (SEMs) of bilayer nanofibrous nerve conduit at different magnifications; (g-j) SEM images of the electrospun nanofibers at different magnifications demonstrating porosity and homogeneous fibrous structures in (g) PLA, (h) PU, and (i, j) PU/MWCNT nanofibrous mats. Multiwalled carbon nanotubes (MWCNTs) embedded in nanofibres are denoted by Red arrowsBack to article page
