Embodiment Construction

[0028] Figures 2A to 2C The sequential steps of an embodiment of the flexible conductive film fabrication mode are schematically shown.

[0029] exist Figure 2A In the illustrated procedure, a suspension 20 comprising carbon nanotubes 24 and chains 26 of linear polymers in a solvent 22 is prepared. Preferably, solvent 20 is hydrophobic. The solvent may be selected from the group comprising dimethylformamide (DMF), tetrahydrofuran (THF) and chloroform. Each chain 26 of the linear polymer supports a series of functional groups 28 comprising π-conjugated groups 30 . Carbon nanotubes 24 are formed by winding one or more graphene sheets into a cylinder. The cylinders are electrically conductive due to the migration of electrons across the graphene, which contains many π-conjugated groups. Thus, the π-conjugated groups 30 of the chains 26 of the linear polymer can be bonded to the π-conjugated groups of the carbon nanotubes 24 through π-stacking.

Abstract

The invention relates to a device that is to be implanted in vivo and includes a stent (46) surrounded, at least partially, by at least one flexible conductive film (54, 56) containing chains of a linear polymer, each of which has carbon nanotubes connected thereto via pi-pi interactions. Said film is functionalized by enzymatic grafting so as to form an electrochemical bioreactor element.

Description

[0001] Cross References to Related Applications [0002] This patent application claims the benefit of priority from French patent application FR14 / 57917, which is hereby incorporated by reference. Background technique [0003] The present invention relates to a method for the manufacture of an electrically conductive film capable of forming an element of an electrochemical bioreactor at the level that is confined between the element contained in the bioreactor and the compounds present in the liquid medium in which the bioreactor is immersed reaction can occur. This reaction may, for example, lead to deformation of the bioreactor, generate an electric potential, or lead to a chemical transformation of a compound that interacts with the bioreactor. [0004] Bioreactors leading to electrical potentials can form sugar / oxygen type (eg glucose / oxygen) biofuel cells or bioelectrodes for biosensors. [0005] A bioreactor that causes a chemical transformation of a compound that int...
