Experimental study demonstrates a microfluidic platform to measure biofilm streamer rheology under shear stress, indicating new opportunities to evaluate mechanical biofilm behavior.
, by inducing controlled variations of the fluid shear stress exerted on the streamers by the flow. Thus, the reproducibility of the formation process and the testing protocol make it possible to perform several consistent experimental replicates that provide statistically significant information. By allowing the systematic investigation of the role of biochemical composition on the structure and rheology of streamers, this platform will advance our understanding of biofilm formation.
