Quantitative Analysis of Scanning Tunneling Microscopy Images of Mixed-Ligand-Functionalized Nanoparticles

Francesco Stellacci, Quy Ong Khac, Javier Reguera Gomez, Christoph Renner

Ligand-protected gold nanoparticles exhibit large local curvatures, features rapidly varying over small scales, and chemical heterogeneity. Their imaging by scanning tunneling microscopy (STM) can, in principle, provide direct information on the architectu ...

Herein, we present a simple microelectrode preparation methodology consisting in coating a platinum wire or a carbon fiber with a thin insulating Parylene C film (e.g. 1–10 μm), to produce SECM probes with a small and constant probe RG (i.e. ratio between ...

In-situ Investigation of Adsorption of Dye and Coadsorbates on TiO2 Films Using QCM-D, Fluorescence and AFM Techniques

Michael Graetzel, Francesco Stellacci, Nicolas Tétreault, Kislon Voitchovsky, Hauke Arne Harms

Simultaneous adsorption of dye molecules and coadsorbates is important for the fabrication of high-efficiency dyesensitized solar cells, but its mechanism is not well understood. Herein, we use a quartz crystal microbalance with dissipation technique (QCM- ...

Photocatalytic and phototoxic properties of TiO2-based nanofilaments: ESR and AFM assays

László Forró, Arnaud Magrez, Andrzej Kulik, Andrzej Sienkiewicz, Katarzyna Pierzchala

There is uncertainty in understanding of the relationship between physico-chemical parameters of nanosized titanium dioxide (nano-TiO2) and its toxicity when brought into contact with living cells. This study provides a multidisciplinary experimental insig ...

Scanning Near-Field Optical Microscopy of Living Cells in Liquid, Elaboration of New SNOM Probes and Detection Methods

Kanat Dukenbayev

The aim of the present PhD thesis is the elaboration of new, home-made Scanning Near-field Optical Microscope (SNOM or NSOM), and the demonstration of its great potential for high-resolution topography and fluorescence investigations of soft and solid samp ...

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 ...
