Photothermal Off-Resonance Tapping for Rapid and Gentle Atomic Force Imaging of Live Cells

Georg Fantner, John McKinney, Adrian Pascal Nievergelt, Haig Alexander Eskandarian, Charlène Cécile Geneviève Brillard

Imaging living cells by atomic force microscopy (AFM) promises not only high-resolution topographical data, but additionally, mechanical contrast, both of which are not obtainable with other microscopy techniques. Such imaging is however challenging, as ce ...

High-speed photothermal off-resonance atomic force microscopy reveals assembly routes of centriolar scaffold protein SAS-6

Pierre Gönczy, Adrian Pascal Nievergelt, Georg Fantner, Niccolo Banterle, Santiago Harald Andany

The self-assembly of protein complexes is at the core of many fundamental biological processes1, ranging from the polymerization of cytoskeletal elements, such as microtubules2, to viral capsid formation and organelle assembly3. To reach a comprehensive un ...

Digitally controlled analog proportional-integral-derivative (PID) controller for high-speed scanning probe microscopy

Georg Fantner, Maja Dukic Pjanic, Nahid Hosseini, Adrian Pascal Nievergelt, Santiago Harald Andany, Chen Yang

Nearly all scanning probe microscopes (SPMs) contain a feedback controller, which is used to move the scanner in the direction of the z-axis in order to maintain a constant setpoint based on the tip-sample interaction. The most frequently used feedback con ...

Division site selection linked to inherited cell surface wave troughs in mycobacteria

Georg Fantner, John McKinney, Neeraj Dhar, Adrian Pascal Nievergelt, Pascal Damian Odermatt, Haig Alexander Eskandarian, Mélanie Thérèse Marie Hannebelle, Joëlle Xiao Yuan Ven

Cell division is tightly controlled in space and time to maintain cell size and ploidy within narrow bounds. In bacteria, the canonical Minicell (Min) and nucleoid occlusion (Noc) systems together ensure that division is restricted to midcell after complet ...

Data-Driven Controller Design for Atomic-Force Microscopy

Alireza Karimi, Georg Fantner, Adrian Pascal Nievergelt, Christoph Manuel Kammer

A novel method to design data-driven, fixed-structure controllers with H2 and H∞ performance objectives is presented. The control design problem is transformed into a convex optimization problem with linear matrix inequality constraints, which can be solve ...

Method and apparatus of using a scanning probe microscope

Georg Fantner, Adrian Pascal Nievergelt, Jonathan David Adams

a scanning probe microscope for high-speed imaging and/or nanomechanical mapping. The microscope comprises a scanning probe comprising a cantilever with a tip at the distal end; and means for modulating a tip-sample distance separating the tip from an inte ...

A monolithic MEMS position sensor for closed-loop high-speed atomic force microscopy

Georg Fantner, Nahid Hosseini, Adrian Pascal Nievergelt, Jonathan David Adams

The accuracy and repeatability of atomic force microscopy (AFM) imaging significantly depend on the accuracy of the piezoactuator. However, nonlinear properties of piezoactuators can distort the image, necessitating sensor-based closed-loop actuators to ac ...

Harnessing the damping properties of materials for high-speed atomic force microscopy

Jürgen Brugger, Georg Fantner, Adrian Pascal Nievergelt, Jonas Grossenbacher, Blake William Erickson, Jonathan David Adams

The success of high-speed atomic force microscopy in imaging molecular motors1, enzymes2 and microbes3 in liquid environments suggests that the technique could be of significant value in a variety of areas of nanotechnology. However, the majority of atomic ...

High-Resolution Correlative Microscopy: Bridging the Gap between Single Molecule Localization Microscopy and Atomic Force Microscopy

Aleksandra Radenovic, Georg Fantner, Lely Feletti, Adrian Pascal Nievergelt, Pascal Damian Odermatt, Hendrik Georges Deschout, Arun Shivanandan, Radek Jankele

Nanoscale characterization of living samples has become essential for modern biology. Atomic force microscopy (AFM) creates topological images of fragile biological structures from biomolecules to living cells in aqueous environments. However, correlating ...
