Figure 5From: Affinity for, and localization of, PEG-functionalized silica nanoparticles to sites of damage in an ex vivo spinal cord injury modelPSiNP Accumulations visualized by SEM. The cross sectional SEM images of injured spinal cord (a) and uninjured spinal cords located at site #1 (b), site #2 (c), and site #3 (d) upon immediate post treatment with TMR-PSiNPs. Some, but not all, of individual and aggregated nanoparticles have been highlighted in green and yellow. Note the existence of dense particles in Figure 6a.Back to article page
