Confocal microscope images of AlexaFluor 488 and Qdot 655 labeled CSCNT-cellulase showed alternative appearance and disappearance of cellulaseAlexa 488 patches within CSCNTQdot 655 (Fig. 3). This observation led to a conclusion that nanotubes exhibit ultrafast random motion with respect to the attached cellulase molecules, which act as either joints or molecular springs within the CSCNT-cellulase microparticle. This kind of motion is believed to be due to the heterogeneous distribution of the adsorbed OG
molecules onto the nanotube surface. Therefore, the momentum exerted by the Brownian movement of such small molecules is distributed heterogeneously along the CSCNT axis. The dynamic behavior of CSCNT with respect to the joint-cellulase molecules in OG solution was proposed to induce a physical force that synergistically adds to transfection efficiency.
