Long-life plastic optical fiber probes for scanning near-field optical microscope

Giovanni Dietler, Serguei Sekatski, Anton Smirnov, Ekaterina Rostova

Nowadays, sharpened glass fiber - made probes attached to a quartz tuning fork (TF) and exploiting the shear force - based feedback are by far the most popular in the field of SNOM. These probes are expensive, very fragile and their fabrication is difficul ...

Real-time binding kinetics of ligand-receptor interactions : development and application of a label-free optical biosensor for living bacteria

Ekaterina Rostova

In principle, a major goal in drug development is to design a high-affinity compound with an appropriate pharmacological response, which requires understanding of physical processes underlying the drug-target interaction, affinity and specificity. This dru ...

Kinetics of Antibody Binding to Membranes of Living Bacteria Measured by a Photonic Crystal-Based Biosensor

Giovanni Dietler, Serguei Sekatski, Carine Ben Adiba, Ekaterina Rostova

Optical biosensors based on photonic crystal surface waves (PC SWs) offer a possibility to study binding interactions with living cells, overcoming the limitation of rather small evanescent field penetration depth into a sample medium that is characteristi ...

Single molecule fluorescence resonance energy transfer scanning near-field optical microscopy: potentials and challenges

Giovanni Dietler, Mounir Driss Mensi, Serguei Sekatski, Kanat Dukenbayev, Anton Smirnov, Ekaterina Rostova, Andrey Mikhaylov

A few years ago, single molecule Fluorescence Resonance Energy Transfer Scanning Near-Field Optical Microscope (FRET SNOM) images were demonstrated using CdSe semiconductor nanocrystal-dye molecules as donor-acceptor pairs. Corresponding experiments reveal ...
