Laboratory for Bio- and Nano- Instrumentation

Student projects

We are a lab at the crossroads between instrumentation, microfabrication, and nanoscale biology. Our main expertise is in scanning probe microscopy.

Instrumentation

Our two main research axes are high speed atomic force microscopy and the combination of different microscopy techniques.

Microfabrication

We focus mainly on the fabrication of various AFM cantilevers. Our approach is to optimise the performance through material engineering.

Nanoscale Biology

We use AFM and other scanning probe techniques to understand biology at various spatial and temporal scales.

Bacteria under the microscope: a new growth model for tuberculosis

— New research has shed light on how mycobacteria grow. This discovery could explain why some members of this family of single-celled organisms, which includes the bacillus that causes tuberculosis, can develop resistance to antibiotics

Bacteria must be “stressed out” to divide

— Bacterial cell division is controlled by both enzymatic activity and mechanical forces, which work together to control its timing and location, a new study from EPFL finds.
