Dont just look at it but feel it! Feel the smooth texture at the centre of the EPS, feel its subtle interaction with the curli expressed by the E. coli on the edge. It was also a beautiful mistake how this film was obtained, simply a tilted substrate, and the medium-air interface plays the magic.3 RDPLACESean Booth, University of OxfordCHEMOTACTIC CARNAGEAs bacteria attach to a surface to form a biofilm, many cells burst, releasing red-stained DNA, which is a key polymer in biofilms. In this microfluidic cell, nutrients and time flow from left to right. A gradient of antibiotics from top to bottom counterintuitively attracts cells of Pseudomonas aeruginosa to crawl upwards. The antibiotic triggers the production of their own return fire tailocins in elongated and blue cells, to attack the perceived competitor. These cells then burst, releasing their attack and red-stained DNA, which accumulates over time, filling the biofilm.48'
