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 mechanisms
by 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.
