Recent insights into the rapidly emerging field of bacterial sensing and biofilm monitoring for infection diagnostics are discussed as well as recent key developments and emerging technologies in the field. Electrochemical sensing of bacteria and bacterial biofilm via synthetic, natural, and engineered recognition, as well as direct redox‐sensing approaches via algorithm‐based optical sensing, and tailor‐made optotracing technology are discussed. These technologies are highlighted to answer the very critical question: “how can fast and accurate bacterial sensing and biofilm monitoring be achieved? Following on from that: “how can these different sensing concepts be translated for use in infection diagnostics? A central obstacle to this transformation is the absence of direct and fast analysis methods that provide high‐throughput results and bio‐interfaces that can control and regulate the means of communication between biological and electronic systems. Here, the overall progress made to date in building such translational efforts at the level of an individual bacterial cell to a bacterial community is discussed. In this review, the overall progress made to date in building portable, easy‐to‐use bacterial biosensors biofilm‐monitoring tools for infection diagnostics is summarized and the recent translational efforts at the level of an individual bacterial cell to the bacterial community by focusing on the state‐of‐the‐art technologies are highlighted.
