Preparation of Multiwall Carbon Nanotubes Embedded Electroconductive Multi-Microchannel Scaffolds for Neuron Growth under Electrical Stimulation

Figure 2

SEM images and RAMAN spectra of multi-microchannel scaffolds. (a)-(d): SEM images of multi-microchannel MWCNT-agarose scaffolds with MWCNT concentrations of 0% wt, 0.025% wt, 0.05% wt, and 0.1% wt, respectively. (e) showed scaffold with 0.1% wt MWCNTs on the surface at 30 K magnification. (f)-(i) Longitudinal section images of multi-microchannel MWCNT-agarose scaffolds with MWCNTs concentrations of 0% wt, 0.025% wt, 0.05% wt, and 0.1% wt, respectively. (j) showed the characteristic peak of MWCNTs could be observed at about 1350 cm^-1 in 0.1% wt MWCNT-agarose scaffold.
