Artificial Mother-of-Pearl created using Bacteria

This abalone shell is a natural form of nacre — also known as mother-of-pearl — an exceptionally tough material found in shells and pearls. Rochester biologists have developed an innovative method for creating nacre in the lab — and maybe on the moon.

A biologist invented an inexpensive and environmentally friendly method for making artificial nacre using an innovative component: bacteria. The artificial nacre is made of biologically produced materials and has the toughness of natural nacre, while also being stiff and, surprisingly, bendable. The method used to create the novel material could lead to new applications in medicine, engineering – and even constructing buildings on the moon.

The impressive mechanical properties of...
