Descriptif de l’UE

The objective of this course is to introduce students to the growing field of bioinspired and biomimetic materials, to offer a truly inter-disciplinary course at the frontier of material science and life sciences, which will allow them to communicate efficiently in an ever-increasing multidisciplinary research environment. The professors offering the course are faculties from Nanyang Technological University (NTU) in Singapore. Therefore some of the courses will be offered during a visit in UPMC of NTU faculties and the rest will be seen in video (with a UPMC tutor in the room). The assessment will be as follows: quiz/short-questions examinations: 30% ; Essay/paper : 70% among which 40% are on the written document and 30% on an oral presentation.

Objectifs d’apprentissage

At the end of the course, students will be able to first: identify and explain the numerous strategies used by nature to solve materials problems in an efficient way, and second: describe the chemical and physical concepts by which biological materials are processed and interprete their critical structure/function relationships (case studies will involve materials relevant to the human body (collagen, elastin, bone) as well as those from model organisms (arthropods, mollusks, cephalopods)). The course will also be the opportunity to learn some of the basic concepts and techniques used in life sciences (proteomics tools, gene cloning and protein engineering, protein chemistry), which will allow students to communicate more efficiently with life scientists in their future research activities.


This course is intended to be accessible to all the students with a Master 1 in Chemistry or Physics. The course 4C703 (Material, Surfaces and Interfaces) and the Material science interdisciplinary profile will be an advantage. This course is part of the Interdisciplinary International profile Material Science and Nanotechnologies at the BioInterfaces (MatNanoBio) in conjunction with NTU (Singapore) with the courses “Material Surfaces at the BioInterfaces” and “Plasmonics and nano-optics for Chemistry & BioInterfaces”.
