Answer 1:
There is quite some research done here at UCSB
that involves biomimetic. Dan Morse looks
at biomimeralization. Abalone shells for
example are remarkably strong and the calcium
(mineral) is deposited by the animal in a
precision of nanoscale fabrication, controlled in
a way we humans cannot do. Understanding how
nature does this and using these mechanisms
researchers will be able to develop new strategies
for the synthesis of high-performance,
nanostructured composite materials. Another
example is the controlled polymerization of
silica. Scientists need extreme conditions
(either high temperature, high pressure or extreme
pH) to do this reaction while nature can do many
reactions at ambient temperature, normal pressure
and neutral pH (degree of acidity).
Dan Morse's group is looking at a sponge
that is able to build glass needles inside its
body for protection. The needles are made of
silica (glass) and are synthesized under very mild
conditions.
Another professor here at UCSB is Herbert Waite
who is learning from mussels how to develop
a "super glue" that also works under water.
"It is self-evident that man-made adhesives do not
stick very well to wet surfaces. Marine organisms
such as barnacles, limpets, kelps, and mussels,
however, produce glues that do very well
underwater."
Mussels such as Mytilus attach themselves to
surfaces by making a bundle of threads
collectively referred to as the byssus. Byssal
threads are permanent hold fasts and extraordinary
biomolecular materials; they are strong, rapidly
made, durable and adhere to a wide variety of
surfaces including glass, metal, paraffin and
bone. You can learn more about his research by

Lately his group is also looking at a marine
bloodworm whose jaws exhibit an extraordinary
resistance to abrasion.
All this research has not yet let to the
development of new materials. It takes a long time
to do this, since researchers first have to
understand how nature does it and then try to
imitate it. But one day we might use a glue that
came from research that was done here at UCSB. Click Here to return to the search form.
