Implantable biocompatible reactor

The invention concerns a bioreactor obtained by compressing a mixture of an enzyme, a conductor and chitosan. The conductor can consist of carbon nanotubes. This bioreactor can be produced according to the following steps: preparing a mixture of powders in which the proportion of enzyme powder relat...

Beschreibung
Zusammenfassung:	The invention concerns a bioreactor obtained by compressing a mixture of an enzyme, a conductor and chitosan. The conductor can consist of carbon nanotubes. This bioreactor can be produced according to the following steps: preparing a mixture of powders in which the proportion of enzyme powder relative to a carbon nanotube powder is of the order of 50/50 by weight; preparing a viscous solution of chitosan in a ratio of 5 to 15 (in mg) of chitosan to 0.75 to 1.25 (in ml) of acetic acid diluted to 0.4 to 0.6% by volume in water; adding the viscous chitosan to the mixture of powders in a proportion be weight of 3 to 5 of powder to 5 to 10 of chitosan; carrying out a first compression followed by light grinding; carrying out a second compression to produce a pellet; and drying at ambient temperature.
