A research work on molluscs nacre opens new doors for its possible use in biomedicine
Date:2/12/2009

e is made up of blocks of aragonite separated by membrans of polysaccharides and proteins, just like bricks and mortar in a wall.

The scientist whi ve studied gastropods' nacre in detail, revealing that it grows in terraces because it is limited by a membrane (superficial membrane) which covers and protects it from sea water when the animal goes into its shell. Such superficial membrane must carry out different tasks in order to permit the prodcution of nacre and therefore it is "a wonderfully complex structure", according to the authors of this work. This article has showed how the superficial membrane organizes nacre in towers and how mineral blocks are conected through a central column.
