Abstract

original image

N-Fluorenyl-9-methoxycarbonyl-protected amino acids are used as surfactants for carbon nanotubes and their interactions are modeled using quantum mechanical computations. These surfactants are then converted into enzymatically activated CNT surfactants that create homogeneous aqueous nanotube dispersions on-demand under constant and physiological conditions (see image).
