  • Figure 1. A pictorial representation of a
    nanoscale process with supramolecular unit
    operations, scaffold and transport mechanisms.
    The two units are nanoreactors (top left --
    Richeter and Rebek, 2004 bottom right Kang and
    Rebek, 1997). The structural scaffold can be made
    of (a) crossed semiconductor nanowires (Zhong et
    al., 2003) or (b) DNA tiles (Park et al., 2005).
    Between the supramolecular unit operations,
    molecules may be transported selectively through
    (a) shuttles (Balzani et al., 2000), (b) motors
    (Sherman and Seeman, 2004) and (c) nanotubes
    (Blau and Fleming, 2004).

  • Figure 2. A pictorial representation of nanoscale
    signaling and energy use. In the first
    nanoreactor unit, a signaling network similar to
    (a) Gianneschi et al., 2004 occurs, where a
    signal, P1, triggers a conformation change in S1.
    This change catalyzes the reaction of R1 and R2
    to form P2 and P3. P3 is then transported to the
    second nanoreactor unit, where it is a trigger
    for a reaction similar to (b) Meijer and van
    Genderen, 2003. P3 triggers the dendrimer to
    self-destruct and release its cargo, P5. One can
    envision the dendrimer, R3, being an energy
    storage unit that releases energy-providing P5
    molecules when they are needed in the system.
