<pclass="column"style="float: left; width: 50%; font-size: 2.5vh; padding-right: 40px;">We wanted to create a cell-free biosensor to combine with our bioremediation device to provide a way to quickly detect the target metals cadmium, lead, arsenic or mercury (commonly detected heavy metals in Ghana’s River waters). These biosensors are transcription-only which minimises the device’s necessary components effectively increasing usability and also reducing cost.</p>
