High-performance materials inspired by tooth enamel

Tooth enamel is designed to last years – even decades. Inspired by its strength and structure, University of Michigan researchers have designed a material to withstand vibrations and damage to be used in airplanes, vehicles, and medical implants.

Michigan Engineering is home to 12 highly-ranked departments for both undergraduate and graduate studies, with over 80,000 alumni around the globe. http://engin.umich.edu ----- The researchers recreated the “abiotic tooth enamel” structure by growing zinc oxide nanowires on a chip and layered two polymers over the nanowires. The chip was spun to spread out the liquid, then baked to cure the plastic between coats. 40 layers to are needed to build up a single micrometer. Then, another layer of zinc oxide nanowires is laid down and filled in with 40 layers of polymer, repeating the whole process up to 20 times. The work is led by Nicholas Kotov, the Joseph B. and Florence V. Cejka Professor of Chemical Engineering as well as a professor biomedical engineering, materials science & engineering, and macromolecular science & engineering at the University of Michigan https://che.engin.umich.edu/people/ni...
