Biologists from the University of Rochester has invented an inexpensive and environmentally friendly method of making artificial nacre using bacteria, according to the website of the institution. Faux pearl, received an associate Professor of biology Ann Meyer and her colleagues, has a toughness of natural nacre and thus has flexibility.
The most noted methods of manufacture of artificial mother-of-pearl a complex and energy-intensive. One of the most useful features of nacre obtained from the laboratory of Meyer, that it is biocompatible – that is made of materials that are contained in the human body. This makes it ideal for use in medicine, such as artificial bones and implants.
“If you break an arm, you can insert the metal pin which must be removed after bone healing. The pin is made from our material is tough and durable, and that it does not have to remove,” explains Meyer.
Meyer also says that the pearl can also be an ideal material for building houses on the moon and other planets. The only necessary “ingredients” for creating material to be himself an astronaut and a small tube with bacteria.
“The moon contains large amounts of calcium in the lunar dust, so one of the necessary materials already. The only thing to add to the layers of calcium carbonate is urea,” says the scientist.
In addition, although the nacre is stronger than most plastics, it is very light, especially for vehicles such as aircraft or missiles, where every extra gram means extra fuel.
Earlier it was reported that scientists in Israel have created an artificial heart, printed on a 3D printer. Experts claim that its capabilities are not inferior to the main human body.
