FOREWORD
One of the major drivers in biological research is the establishment of structures and
functions of the 50,000 or so proteins in our bodies. Each has a characteristic 3-
dimensional structure, highly "ordered" yet "disordered"! This structure is essential for
a protein's function and, significantly, it must be sustained in the competitive and
complex environment of the living cell.
It is now being recognised that when a cell loses control, proteins can self-
assemble into more complex supermolecular structures such as the amyloid fibres and
plaques associated with the pathogenesis of prion (CJD) or age-related (Alzheimer's)
diseases. This is a pointer to the wider significance of the self-assembling properties of
polypeptides. It has been long known that, in silk, polypeptides are assembled into ß-
sheet structures which impart on the material its highly exploitable properties of
flexibility combined with high tensile strength. But only now emerging is the
recognition that peptides can Self-assemble into a wide variety of non-protein-like
structures, including fibrils, fibres, tubules, sheets and monolayers. These are exciting
observations and, more so, the potential for materials and medical exploitations is so
wide ranging that over 80 scientists from Europe, USA, Japan and Israel. met 1-6 July
1999 in Crete, to discuss the wide-ranging implications of these novel developments.
Therewas a spiritof excitementaboutthe workshop indicative ofan important
new endeavor. The emerging perception is that of a new class of materials set to
become commercially viable early in the 21st century. This stems from the
opportunities for processing by the self-assembly route combined with the fact, just as
in the case of proteins, that functionality can be designed into the self-assembled
structures. They can be made responsive to pH change, mechanical forces, temperature,
pressure, electro-chemical potential, electrical and magnetic fields, and light. They can
function as sensors and actuators and can act as molecular motors capable of
interconverting energies ( vis-à-vis metabolism). They can even be programmed for
biodegradation! Extraordinary and widely exploitable properties. Particularly in view of
the exceptional thermal stability of peptides (up to 350°C). Nor are production costs
insurmountable. Large scale production by the fermentation or transgenic plant or
animal routes, at the ton level if needed, are already being developed. Projected costs
are as low as a few pounds per kilogram. Applications in tissue engineering, biomedical
devices, industrial fluids and personal care products are all under development. Could
thesenewmaterialsbecomethewonderpolymersof the21stcentury!
The workshop was charged with a vibrant atmosphere as may be expected of
this newly developing interdisciplinary area. As Francis Crick best put it "In Nature
hybrid species are usually sterile, but in science the reverse is often true. Hybrid
subjects are often astonishingly fertile, whereas if a scientific discipline remains too
pure it usually wilts".
In view of the exciting prospects for this new area of endeavor, it was felt that
it would be useful to record the proceedings of the workshop for those unable to attend.
