A novel nanotube–protein functionalization pathway is used to create high concentrations of highly reactive carbon nanotubes (CNTs) and for the efficient functionalization of CNTs with purified biological materials. The approach does not require dilution and reduces crosslinking between nanotubes. The idea is based on solubility differences of treated CNTs in various solvents and a chloroform‐extraction process is used to create water‐soluble (see image; scale bar is 1 μm) and insoluble CNTs.
