International audience; Septins are ubiquitous cytoskeletal filaments that interact with the inner plasma membrane and are essential for cell division in eukaryotes. In cellular contexts, septins are often localized at micrometric Gaussian curvatures

Circular AFM Mode: A New AFM Mode for Investigating Surface Properties

Autor: Pierre-Emmanuel Mazeran, Olivier Noel, Hussein Nasrallah

Publikováno v: MRS Proceedings. 1318

For the first time, a new AFM mode is presented that simultaneously allows the measuring of adhesion and friction forces at different constant and continuous sliding velocities. Our methodology consists of implementing a circular relative displacemen

Circular mode: A new scanning probe microscopy method for investigating surface properties at constant and continuous scanning velocities

Autor: Pierre-Emmanuel Mazeran, Hussein Nasrallah, Olivier Noel

Publikováno v: Review of Scientific Instruments. 82:113703

In this paper, we introduce a novel scanning probe microscopy mode, called the circular mode, which offers expanded capabilities for surface investigations especially for measuring physical properties that require high scanning velocities and/or cont
