Electrowetting on a Dielectric (EWOD) uses electric fields to control droplet shape and motion on solid insulating surfaces, offering silent manipulation without moving parts. A single EWOD electrode allows manipulation of droplet curvature, enabling liqui ...
The thesis will discuss how small objects such as bacteria and viruses can be manipulated on-chip using light via Photonic crystals (PhCs). In particular, PhCs could be used in the context of novel fast antimicrobial susceptibility tests (ASTs). We will se ...
Closed-loop neural implants based on continuous brain activity recording and intracortical microstimulation are extremely effective and promising devices to monitor and address many neurodegenerative diseases. The efficiency of these devices depends on the ...
In this thesis, we explored on-chip high-resolution imaging of the fate of intestinal bacteria and bacterial products in Caenorhabditis elegans (C. elegans). In the first part, we carried out high-resolution z-stack fluorescent imaging of Red Fluorescent P ...
Transition metal hexacyanometallates, so-called Prussian Blue Analogs (PBAs), have received massive attention as aqueous Na-ion battery electrode materials for large-scale energy storage systems not only due to their simple and low-cost synthesis procedure ...
Infectious diseases and antimicrobial resistance are major burdens in developing countries, where very specific conditions impede the deployment of established medical infrastructures. Since biosensing devices are nowadays very common in developed countrie ...
We consider the problem of localizing wireless devices in an ad-hoc network embedded in a d-dimensional Euclidean space. Obtaining a good estimation of where wireless devices are located is crucial in wireless network applications including environment m ...
A 2.4-GHz low power polar transmitter architecture is proposed in this paper. A dynamic biasing circuit, controlled by a digital envelope signal, is used to linearize the input-output characteristic of the overdriven class-C power amplifier. A model of the ...
Functional magnetic micro- and nanoparticles are used in bioanalytical applications as solid carriers for capture, transport and detection of biomolecules or magnetically labeled cells. Colloidal suspensions of such particles provide a large specific surfa ...
Magnetic beads (MB) have now proven to be a powerful tool in both research and biomedical applications. They are available in a wide range of sizes (from nm to several µm) and their surface can be modified with molecules having biological specificities and ...
This paper presents a novel high-frequency tunable band-stop filter concept based on a single MEMS capacitive shunt device which uses meander arm anchoring inductors and with a total size of 300 × 600 μm. Tuning ranges of the central frequency in the order ...
Poly (3,4-ethylenedioxythiophene) (PEDOT) nanoporous layers were prepared with electro-oxidative polymerization using room temperature hydrophobic ionic liquids as a medium. The synthesized highly porous PEDOT films exhibit room temperature conductivity va ...
A sandwich mixer consists of mixing two solutions in a channel, one central laminar flow being sandwiched between two outer flow solutions. The present numerical study considers the convection– diffusion of two reacting species A and B, provided respective ...
In the frame of this thesis, we have developed a novel batch-type technology for the realization of three-dimensional millimeter-size transformers for ultra-small low-power (0.1-1 Watt) applications. The technology is based on the three-dimensional micropa ...
Selective transport and sorting of particles in microfluidic devices by electroosmosis is complicated due to superposition of uncontrolled hydrodynamic pressure contributions on the electroosmotic force. In this paper, we present a microfluidic concept for ...
