Life Crystals

Pupa Gilbert, University of Wisconsin – Madison
Department of Physics

Crystalline biominerals cost energy but provide the diverse organisms making them with useful functions, including scaffolding, shielding, locomotion, mastication, gravity, and magnetic field sensing. How these crystals are formed reveals how living organisms harness the laws of physics and chemistry for their evolutionary advantage, but it can also teach us new synthesis strategies for materials with targeted properties. Recent synchrotron spectromicroscopy methods reveal one formation mechanism and one toughening mechanism:

1.   Crystallization by particle attachment in diverse marine organisms, and its implications for changing ocean chemistry.

2.   Slight mis-orientation of nanocrystals in human enamel makes our teeth endure decades of mastication without breaking.
