Innovative spiral nerve conduits: Addressing nutrient transport and cellular activity for critical-sized nerve defects

Bioactive Materials
Large-gap nerve defects require nerve guide conduits (NGCs) for complete regeneration and muscle innervation. Many NGCs have been developed using various scaffold designs and tissue engineering strategies to promote axon regeneration.

Effect of MWCNT functionalization on thermal and electrical properties of PHBV/MWCNT nanocomposites

, 2015
Pristine multiwalled carbon nanotubes (P-MWCNTs) were functionalized with carboxylic groups (MWCNT-COOH) through oxidation reactions and then reduced to produce hydroxyl groups (MWCNT-OH).
