The main purpose of this thesis is to explore a new concept of SNOM probes. In order to produce more reliable and reproducible tips, we propose to graft a single gold particle of 60 nm diameter onto the aperture of a SNOM probe. The expected advantage of s ...
In this thesis a new scanning near field optical microscope based on an apertureless scattering technique is introduced for resolving optical properties of surfaces with lateral resolution reaching 10 nm and better. The construction of the instrument is ba ...
Chalcogenide glass optical fibers were fabricated into functional apertured probes for near field scanning infrared microscopy. Probe fiber tips were chemically etched and aluminum coated for the purpose of simultaneously collecting near field shear force ...
In view of future generations of biosensors, the immobilization of biomolecules onto selected materials with a well controlled topical addressability is of primary importance. Photoimmobilization is a technique allowing the immobilization of a biomolecule ...
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 ...
Lamellipodia of crawling cells represent both the motor for cell advance and the primary building site for the actin cytoskeleton. The organization of actin in the lamellipodium reflects actin dynamics and is of critical importance for the mechanism of cel ...
Aerolysin is a channel-forming toxin that must oligomerize in order to become insertion-competent. Modeling based on the crystal structure of the proaerolysin dimer and electron microscopic images of the oligomer indicated that a loop in domain 3 must move ...
Optical near field microscope for use with different, including differential contrast, methods. Microscope has a near field illuminating light source probe (3) and a photo-detector for detection of light from the object (6). Said detector has electronics f ...
We present a digital method for holographic microscopy involving a CCD camera as a recording device. Off-axis holograms recorded with a magnified image of microscopic objects are numerically reconstructed in amplitude and phase by calculation of scalar dif ...
A fiber-based flexural actuator was developed using a patterned piezoelectric ZnO/electrode fiber coating on a standard telecommunications optical fiber. The actuator was composed of a concentric inner Cr/Au electrode, a thick sputtered ZnO coating, and an ...
