Researchers have continued to work on 3D scaffold using compression molding and salt leaching
technique to mimic trabecular pattern of bone. Multiple layers of SWNT and gelatin were coated
using LbL self-assembly technique on 3D porous PCL scaffold. This technique might increase the
mechanical properties of the 3D scaffold while maintaining high levels of porosity and interconnec-
tivity, mimicking highly porous trabecular bone and possibly facilitate osteogenic cell proliferation
by utilizing CNTs electrical properties.
