Médaille de bronze 2022 : Marco Faustini, chimie des matériaux
Intro
Open media modal
Observing and understanding nature better to replicate its genius... This is not a new idea but the concept of bio-inspiration now appears to be more than ever a major trend for innovation. In health, robotics, ecology, chemistry, engineering sciences, etc., CNRS researchers will show you their research and its applications which were inspired by nature. Welcome to the bio-inspired world!

Ifremer teams have found a bacterium at the bottom of the oceans that could contribute to the development of regenerative medicine. The aim of teams from the Inserm 791 “Osteo-articular and dental engineering laboratory” research unit and Ifremer is to manufacture injectable gels capable of stimulating the regeneration of cartilage or bone from stem cells. Their key ingredient is a polysaccharide produced by a bacteria of marine origin called Alteromonas infernus.

Taking inspiration from diatoms, cellular microorganisms which surround themselves with a glass shell in water, we now know how to manufacture different materials, at room temperature, which are very useful for numerous industrial and medical applications.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
