There are several unresolved issues present when it comes to the experiment part of the project.

The following issues are:

Zimmer & Peacock pH sensor

Keeping the cells alive inside the chip

In order to achieve useful results

Possible solutions:

Controlling the CO2 levels

Environment

Possible solutions:

Air bubbles

When filling chambers with liquid, the bubbles can result in the cells dying prematurely and/or inhibiting the flow.

Possible solutions to air bubbles:
