Abstract
We show the suppression of fluctuating background temperatures on a microfluidic chip with an integrated differential heat flux sensing system for the measurement of bacterial growth through metabolic heat. In contrast to previous systems involving more controlled thermal environments and larger sensors and microfluidic channels, we expose a smaller chip with a smaller sensor to a thermally fluctuating environment without additional isolation. We demonstrate that, leveraging the differential sensing strategy, our system can detect bacterial growth in the exponential growth phase, despite the large environmental temperature fluctuations.
