Long-Term Regeneration and Functional Recovery of a 15 mm Critical Nerve Gap Bridged by Tremella fuciformis Polysaccharide-Immobilized Polylactide Conduits
(a) ATR-IR spectra of PLA surface immobilized with TF (PLA/TF) after air plasma activation. The original spectrum is marked as “0 wk,” while spectra marked “2 wk” and “4 wk” indicate those obtained after the sample was put in PBS for 2 and 4 weeks. (b) SEM image for the cross-section of TF modified PLA. (c) The permeabilities of the original and TF-immobilized PLA substrates are shown.
