Fig. (14).

A kinesin molecule as it carries a vesicle during its “walk” along a microtubule. The mechanistic connotation of the image is, however, underlain by an array of molecular recognition interactions and the corresponding co-assembly phenomena. Hence, the soft chemical aspect of spontaneous assembly ought to be integrated with the hard chemical aspect of litho-graphic and other rigid methods of control of the systems in question in order to maximize the synthetic, processing and functional effectiveness of scientific endeavors.
