簡介 :
Self-assembly is a route to processing of chemical products that relies
on information content built into the process precursors.
Self-assembly occurs frequently in biology but translating that
bioinspiration to controllable chemical processing
presents many interesting problems.
Self-assembly is guided by information content intrinsic to
the assembling units, in which multiple levels of structural organization
are built into a product. Owing to the complexity of structures
formed and the nominal ease of spontaneous organization,
self-assembly is increasingly being examined as
a practical chemical processing method.
The resultant structures are being actively explored as new materials,
surface treatments, catalysts, membranes, photonic materials
and electronic devices, to name a few areas of
current engineering exploration.Self-assembly is
one of the key mechanismsby which nature builds products,
from biological molecules such as proteins to
larger structures such as cells and extracellular matrices,
the spatial arrangement of atoms is determined,
in large part, by information built into the assembling units.
Complexity, in the sense of development of emergent properties
of an assembly that cannot readily be envisioned from the constituents,
can arise spontaneously during self-assembly and often does,
especially in biological systems.
We are only beginning to develop sufficiently sophisticated synthetic
assemblers to mimic biology in this way.
Indeed, other routes to self-organization,
including those far from equilibrium, may also be of
interest for nanotechnology.
A challenge for engineers is to develop the practical routes to
technologically important self-assembly processes.
Applications will be to biomaterials, porous materials,
molecular electronics and many other areas.
Hurdles that must be overcome include
the precision synthesis of precursors,
mastering the kinetics and dynamics of such processes, scale-up, and
the characterization and control of self-assembly products and processes.
Prospects for success and current efforts in these areas will be discussed.
