Hydrogel Nanofilaments via Core-Shell Electrospinning - Fig 1

<p>a) SEM micrograph presenting ribbon-like core-shell PLCL/PAAm nanofibre (EA3) (see file <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129816#pone.0129816.s001" target="_blank">S1 Fig</a>). b) Fluorescent nanofilaments extracted as core from nanofibre. The contour length of the longest nanofilament equals 104 μm.
