Abrégé
(EN)
The invention is a series of soft lithographic methods for the microfabrication of biopolymer scaffolds for use in tissue engineering and the development of artificial organs. The methods present a wide range of possibilities to construct two-and three-dimensional scaffolds with desired characteristics according to the final application. The methods utilize an elastomer mold which the biopolymer scaffold is cast. The methods allow for the rapid and inexpensive production of biopolymer scaffolds with limited specialized equipment and user expertise.

L'invention concerne une série de méthodes lithographiques douces destinées à la microfabrication de matrices de biopolymères utilisées en génie tissulaire et dans le développement d'organes artificiels. Ces méthodes présentent une vaste gamme de possibilités élaborées pour construire des matrices bi- et tridimensionnelles dotées de caractéristiques souhaitées, en fonction de l'application finale. Ces méthodes utilisent un moule élastomère dans lequel la matrice du biopolymère est moulée. Ces méthodes permettent de produire, de manière rapide et bon marché, des matrices de biopolymères avec un équipement spécialisé limité et une expertise d'utilisateur.
