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 ...

Ultrasharp carbon whisker optical fiber probes for scanning near-field optical microscopy

Giovanni Dietler, Mounir Driss Mensi, Serguei Sekatski, Andrey Mikhaylov

We report the growth of ultrasharp carbon whiskers onto apertured near-field optical glass fiber probes. The ultrasharp carbon whiskers are produced by the electron-assisted dissociation of residual oil vapors present in the vacuum chamber during the elect ...

Scanning Near-Field Optical Microscopy Study of Biomolecules, Elaboration of New SNOM Probes and Detection Methods

Mounir Driss Mensi

The combination of the topographic resolution of Scanning Probe Microscopy with the subwavelength information of light/matter interaction leads to a new instrument called Scanning Near-field Optical Microscope (SNOM). This new instrument is an ideal tool t ...

Scanning Near-field Optical Microscopy-based Study of Local Dynamics of Receptor-Ligand Interactions at the Single Molecule Level

Giovanni Dietler, Mounir Driss Mensi, Serguei Sekatski, Kanat Dukenbayev

A scanning near-field optical microscope (SNOM)-based modification of the method to study the dynamics of single molecule receptor?ligand interactions exploiting the fluorescence imaging by total internal reflection fluorescence microscopy is introduced. T ...

Near-field scanning optical microscopy using polymethylmethacrylate optical fiber probes

Giovanni Dietler, Mounir Driss Mensi, Serguei Sekatski, Kanat Dukenbayev

We report the first use of polymethylmethacrylate (PMMA) optical fiber-made probes for scanning near-field optical microscopy (SNOM). The sharp tips were prepared by chemical etching of the fibers in ethyl acetate, and the probes were prepared by proper gl ...

Stable -Synuclein Oligomers Strongly Inhibit Chaperone Activity of the Hsp70 System by Weak Interactions with J-domain Co-chaperones

Giovanni Dietler, Hilal Lashuel, Mounir Driss Mensi, Pierre Goloubinoff

alpha-Synuclein aggregation and accumulation in Lewy bodies are implicated in progressive loss of dopaminergic neurons in Parkinson disease and related disorders. In neurons, the Hsp70s and their Hsp40-like J-domain co-chaperones are the only known compone ...
