Title: 3D-printing electricity-producing bacteria: a new paradigm for developing graphene-based biosensors

Duration: 2019 - 2020

Research groups: Bioe



The overall goal of PRINTBIO is to “domesticate” and to 3D print the electricity-producing bacteria form the genus Geobacter to convert this strain in à-la-carte bioelectrochemical biosensor using graphene-based screen printed electrode as electrochemical platform.

General activities

We are following a 3D printing approach to create Geobacter-derived functional using a electroconductive and biocompatible hydrogel. Moreover we will follow a system biology approach to test genetically engineered. Geobacter strains able to switch on-off the capacity of electricity production conditioned to the presence of a specific analyte.

Expected results

To develop a proof of concept case regarding the use of a novel bioelectrochemical 3D-platform for detecting pollutants by using the metabolism of electroactive bacteria from Geobacter genus.
