We analyse the collective behaviours of Escherichia coli (E. coli) active matter. The individual movements of these E. coli can be accurately tracked and examined using a recently developed machine learning software called DeepTrack (Midvedt et al., 2021). This provides greater insight into the chaotic dynamics of E. coli swarms as well as the potential to critically assess current theoretical models. DeepTrack analysis can also be applied in more complex environments including interactions with microstructures made with photolithography. Analysing the movements of E. coli active matter with DeepTrack has promising implications in engineering and biomedical applications.
