Tracking cell molecules with carbon nanotubes

A thin carbon nanotube is attached to a molecular motor (yellow) that moves along microtubule filaments (green) that form the transport network of cells. This transport occurs in the highly crowded environment of the cytoplasm that includes a network of actin filaments (red). The fluorescent nanotube serves as a beacon for both the transport along the microtubule, as well as the buffeting of the microtubule by the highly agitated surrounding cytoplasm. Image: M. Leunissen, Dutch Data Design.
