The morphology, stability and reactivity of nanometre-sized particles (Au, Pt) is investigated on three different supports. Gold nanoparticles with a diameter comprised between 4 and 6nm are stabilized in nanosized pits of well defined depth in highly orie ...
This thesis looks at surface-bound nanowires and nanoparticles, the mechanical and the metrological properties of which are of practical importance in the realization of nanometer-scale electronics. Atomic force microscope (AFM) was the main instrument of ...
Inkjet printing of functional materials, photolithography and micromolding are 3 different techniques largely used in the field of micro-electromechanical systems (MEMS) with increasing interest for the fabrication of new devices and the development of new ...
Scanning electrochemical microscopy (SECM) has been used to image latent fingermarks enhanced by adsorption of gold nanoparticles onto which silver is chemically deposited, a process known as ‘‘multi-metal-deposition’’ (MMD). ...
As conventional fabrication techniques reach their limits novel techniques are needed for fabrication of structures in the nanometer range. This thesis investigates new methods to create metal nanostructures or nanoparticles with an STM tip or a sharp meta ...
The ligand shell that coats, protects, and imparts a large number of properties to gold nanoparticles is a 2-D self-assembled monolayer wrapped around a 3-D metallic core. Here we present a study of the molecular packing of ligand shells on gold nanopartic ...
Mixed monolayers, which on flat surfaces phase-separate into randomly shaped domains, spontaneously form ordered rings of alternating composition when assembled around the core of a monolayer-protected gold nanoparticle (see figure). It is shown that it is ...
Substrates with 1-dimensional nanosize grooves were prepared using extreme-ultraviolet interference lithography (EUV-IL), wherein gold nanoparticles were self-assembled to form 1-dimensional structures. To measure the electrical properties of gold nanopart ...
We explored a very interesting gold nanoparticle system-pegylated gold in colloidal solution-and analyzed its uptake by mice colorectal adenocarcinoma CT26 tumor cells and the impact on the cell's response to x-ray irradiation. We found that exposure to po ...
Non volatile flash memories based on nanoparticles are one of the possible routes to further downscaling of CMOS technology. The increase of scale integration should involve some new features for memory cells such as Coulomb blockade and quantized charging ...
