Food-Gut Human Axis: Sensor Systems in an in-vitro Human Microbial Ecosystem

Project Title: Food-Gut Human Axis: Sensor Systems in an in-vitro Human Microbial Ecosystem

Project Description:

The human gut microbiota produces a great number of metabolites including gases such as H2, CH4, NH3 and CO2. The real-time monitoring of the presence and concentration of these gases along the different regions of the human Gastrointestinal (GI) tract is a potential assessment tool to correlate and understand the effects of different phenomena inside our body, including the effect of different diets, the development of food products, the use of prebiotic and probiotics on the microbial community activity and composition. The aim of this research project  is to develop an array of CNT-based gas sensor to monitor different gases inside an in-vitro GI tract model known as SHIME (Simulator of the Human Microbial Ecosystem) in collaboration with the Micro4Food lab. This aim will be achieved through the following research objectives.

  • To fabricate and test a single CNT gas sensor under a chamber control conditions
  • To fabricate and test an array of CNT-based gas sensor under a chamber control condition and in a single SHIME bioreactor
  • To evaluate the performance of the array CNT-based gas sensor on a SHIME experimental setup
