AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Combining the subwavelength resolution of near-field interactions with the optical contrast mechanisms of classical optical microscopy makes scanning near-field optical microscopy an interesting technique for many applications. In spite of more than ten ye ...
Lateral force microscopy in the wearless regime was used to study the friction behavior of a lipid monolayer on mica. In the monolayer, condensed domains with long-range orientational order of the lipid molecules were present. The domains revealed unexpect ...

A simple method has been developed for the prodn. of Au surfaces which are uniformly flat over large areas. Si wafers serve as substrates for the evapn. of thin Au layers. A glass slide glued onto the Au film allows successful sepn. of the Au layer from th ...
In the present article we describe a new setup for an atomic force microscope in the beetle-type geometry. The microscope consists of a compact head standing on three piezo legs with a fourth central piezo carrying the cantilever tip. We use the laser beam ...
We report on the first successful operation of a scanning force microscope using microfabricated capacitive force sensors. The sensors, which are made from single crystal silicon on insulator wafers, consist of a cantilever spring with integrated tip at th ...
We present an automation technique for the growth of electron beam deposited tips on whole wafers of atomic force microscope cantilevers. This technique uses pattern recognition on scanning electron microscope images of successive magnifications to precise ...
Tendons are composed of collagen and other molecules in a highly organized hierarchical assembly, leading to extraordinary mechanical properties. To probe the cross-links on the lower level of organization, we used a cantilever to pull substructures out of ...
The friction force on a nanometer-sized tip sliding on a surface is related to the thermally activated hopping of the contact atoms on an effective atomic interaction potential. A general analytical expression relates the height of this potential and the h ...
Fluorescence resonance energy transfer (FRET) was obsd. between donor dye mols. deposited onto the sample surface and acceptor dye mols. deposited onto the scanning near-field optical microscope (SNOM) or at. force microscope tip. FRET was obsd. only when ...
We performed lateral force microscopy on thiolipid Langmuir-Blodgett (LB) films physisorbed on mica substrates with a silicon tip of an at. force microscope. The structure of condensed domains, reflecting their sym. morphol., was obsd. The lateral (frictio ...
