Much research is conducted on the biomechanical properties of cells, particularly in cancer research. Cell stiffness and cell adhesion are two properties often studied, because they are important for the functioning of a cell. To study these properties, atomic force microscopy(AFM) is often used, using nanoindentation for stiffness analysis and...

High-Speed Atomic Force Microscopy is widely used for investigating biological architectures and the semiconductor industry. The main limitation comes from parachuting or the Wile E. Coyote effect. Parachuting is the phenomenon where the cantilever taps on the sample towards a steep decrease in height, but does not get adjusted for this decrease...

The discovery of DNA origami nanotechnology has opened new opportunities in this field due to the versatility of the shapes and sizes that can be generated, the ease of modification and functionalization with molecular resolution, and its biocompatibility. Using Watson-Crick base pairing as the main driver in the self-assembly procedure, DNA...

The processes that take place within cells are complex. Single-cell analysis is a method that is employed to gain further understanding of the working mechanisms on a single-cellular level. The controlled transport of substances through the cell membrane is important for studying the behaviour and responses of single living cells. Femtopipettes...

Facioscapulohumeral muscle dystrophy (FSHD) is the third most common muscle disease in the world. No cure has been found for FSHD, and current treatments focus on alleviating the symptoms. The disease is caused by a genetic error in 1/1000 - 1/200 of the nuclei in a multinucleated skeletal muscle cell. Studying that specific nucleus, by removing...

Any resonance based sensing method such as AFM or mass sensing using microfluidic cantilevers require high frequency stability. For mass measurement, a stable frequency allows for a lower mass resolution. One of the most commonly used methods to actuate these resonators is using piezoacoustics. A major downside of this method is the presence of...

Microstructure-corrosion property correlation is an open question in the field of materials science. The microstructure of metals and alloys consists of several features with different individual corrosion response. The corrosion behavior of the macroscopic system is an outcome of the complex interaction of the components of microstructure....

High performance machines such as those used in the semiconductor industry, robotics or racing engines have lots of fast moving parts. The dynamic properties of these moving parts are crucial to the performance of the machine. Therefore these moving parts have to be carefully designed which is often a very time consuming iterative process. In...

In collaboration with the technical university of Twente, Leiden Probe Microscopy (LPM) has built an instrument to study thin film oxide growth during pulsed laser deposition (PLD). Thin filmed (perovskite) oxides have evoked an interest of material scientist, because they inhibit physical properties such as superconductivity, ferromagnetism,...

To facilitate research on the dynamics of micro-cantilevers immersed in liquid, a modal test setup was designed. Modal testing is a powerful form of dynamic testing whereby the system's natural frequencies, modal masses, modal damping ratios, mode shapes, and weight of each of these modes at a certain frequency are determined. Micro-cantilever...

The Atomic Force Microscope (afm) is a small scale measuring device, with a lot of benefits over other existing measuring techniques. Unfortunately, measurement speed is not one of them. Many have tried and succeeded to improve the measurement speed, but there is still room for improvement.<br/>By passively lowering the Q-factor, a measurement...

Palladium (Pd) metal membranes are used for the production and effective storage of high purity hydrogen. To overcome the crack and de-lamination of Pd membranes at room temperature during several hydrogen loading and de-loading cycles, a Titanium (Ti) of very small thickness of less than 10 nm is introduced as an intermediate layer between the...

The choice on which cantilever to use for Atomic Force Microscopy (AFM) depends on the type of the experiment being done. Usually, the cantilevers have to be exchanged when a different stiffness is required and the entire alignment has to be repeated. In the present work, we have developed a method to adjust the stiffness of the AFM cantilever...

In this thesis a stealth fiducial marker system for blank wafers is designed, fabricated and validated. The goal of this marker system it to map the coordinates of TNO’s Rapid Nano (a fast optical inspection tool) to the coordinates of scanning electron microscopes and atomic force microscopes. This way defects, that have been detected in the...

The subject discussed in this thesis is the dosing of droplets in the femto (10-15) liter range. In this study, droplets were dispensed using a hollow cantilever atomic force microscope (AFM). Dispensing small volumes finds its applications in for example in single cell manipulation, where a drug is delivered inside a single cell to study the...
