Abstrakt:	Invited for this month's cover picture is the group of Dr. Mathieu Etienne from Centre National de la Recherche Scientifique (CNRS, France). The cover picture shows the building block of the bacterial biocomposite made of Shewanella oneidensis, multi‐walled carbon nanotubes, and protamine. The close look at the bacterial membrane shows how protamine, which is positively charged (in blue), promotes self‐assembly between the negatively charged polymers on the bacterial membrane surface (in red) and the negative surface of multi‐walled carbon nanotubes, allowing direct electron transfer reactions. The background of the image is a detail of a scanning electron microscopy image of the biocomposite deposited on a glassy carbon surface, forming the so‐called electroactive artificial biofilm.
