Bacteria have developed clever strategies over millennia to build biopolymer-based communities with fascinating material properties such as sticking to surfaces, repelling water and oils, and even transporting electrons. Material scientists have been inspired by the versatility of bacterial biofilms to create materials for various applications, seeking to improve properties and expand functionalities. By utilizing natural or modified bacterial biofilms, materials with improved properties have been created for diverse fields ranging from agriculture to construction engineering.
Over millennia, bacteria have developed clever strategies to build biopolymer-based communities in which they can survive even extremely challenging conditions. Such bacterial biofilms come with a broad range of fascinating material properties that-in settings such as medicine, food production, or other areas of industry-make it difficult to remove or inactivate them: they can stick to many surfaces, repel water and oils, and can even transport electrons. Inspired by the outstanding versatility and sturdiness of such bacterial biofilms, material scientists have set out to harness those properties and to create bacterial materials for different applications. However, as the range of technological applications employing biofilms keeps expanding, improved material properties or broader functionalities are desired. Here, such attempts where materials with improved properties were created by making use of either natural or modified bacterial biofilms are reviewed. The areas in which those bacterial materials may be used range from agriculture and (environmental) biotechnology over biomedical and electrical engineering to construction engineering.
