iNANO researchers contribute to exhibition at Steno Museum

The exhibition ‘Profession and Passion – a Life in Science’ is launched at the Steno Museum, Aarhus University. iNANO researchers have contributed to the exhibition on what impels researchers and how science and passion live alongside each other.

AU Researchers perform nanodissection using Atomic Force Microscopy (AFM) and unveil how cable bacteria conduct energy. The image shows micrograph (left) of filamentous Desulfobulbaceae and AFM topography (Right) og the outer membrane after nanodissection. Image: Mingdong Dong
The left column, bacterial cable under optical microscopy, which is hybridized with a specific ELF654 FISH and DAPI probe. The middle column, three kinds of cell junctions. The right column, AFM topography and Young’s modulus (logarithm) map of inside of outer membrane after nanodissection. The black dashed arrows indicate cell junction. The solid arrows indicate one string attaching at the inner face of outer membrane. Image: Mingdong Dong

Nanodissection unveils how bacteria conduct energy

Recent discoveries show that cable bacteria can function as electrical wires, however it is unclear how it is possible to have long-range electron transfer through these cobweb thin bacterial chains. Using Atomic Force Microscopy as a nanoscalpel AU researchers now bring us closer to understanding the interior structure of the bacteria.
