Abstract

Given the importance of nanomaterials for medicine, health and biological sciences, a method for reliable intra-cellular tracking of nanocarbon materials at ultra-low concentrations was investigated. Namely, hyperspectral imaging of DNA-functionalized single-walled carbon nanotubes inside neural stem cells was demonstrated, over several mitosis cycles, also in a 3D z-stacking mode.
