New Procedure that allows them to mimic the complex fine structure of biological composite materials, such as teeth or seashells.
Researchers at ETH Zurich, Switzerland, have created a new magnetically guided material to replicate structure of natural teeth.
Their method is called "magnetically assisted slip casting" (MASC). The method involves pouring a suspension of magnetized aluminum oxide platelets into a mold.
The researchers produced an artificial tooth using the MASC method, resulting in a very similar material to that within natural teeth.
Andre Studart, Professor of Complex Materials, said that they were able to produce a tough, multi-layered material based on the construction principle of teeth or seashells.
"The wonderful thing about our new procedure is that it builds on a 100-year-old technique and combines it with modern material research," says Studart's doctoral student Tobias Niebel, co-author of a study just published in the specialist journal Nature Materials.
