1. An optically reactive core-shell microfiber comprising:
a core comprising:
a first polymer; and
a plurality of optically reactive, functionalized single walled carbon nano tubes (SWCNTs) dispersed within the polymer; and
a shell comprising:
a second polymer disposed coaxially about the core,
said second polymer comprising a biocompatible, biodegradable, bioresorbable polymer,
said microfiber having a diameter (Df) in the range of 0.5 μm to 30 μm, a core diameter size (Dc) in the range of 0.25 μm to 20 μm, and a shell thickness (Ts) range of 0.25 μm to 10 μm.
