The main objectives of bioprocesses are to reliably deliver drugs in a relatively short time frame with high quality within a tight regulatory framework. Bioprocesses are highly complex, the level of automation is moderate, and there is constant pressure to improve efficiency and costs. In addition, climate change and resource scarcity...

Phospholipid-coated microbubbles with a uniform acoustic response are a promising avenue for functional ultrasound sensing. A uniform acoustic response requires both a monodisperse size distribution and uniform viscoelastic shell properties. Monodisperse microbubbles can be produced in a microfluidic flow focusing device. Here, we investigate...

Mechanical forces are integral to the functionality and behavior of biological systems, from the cellular to the molecular level. Acoustic force spectroscopy (AFS), an emerging field, seeks to explore these intricate dynamics. Traditional methods in AFS, particularly those using bulk acoustic wave (BAW) devices, still lack sample visibility and...

Small satellites require efficient propulsion systems for attitude and orbit control. This thesis focuses on the development and characterization of two distinct types of micro-resistojet thrusters, namely Vaporizing Liquid Micro-resistojet (VLM) and Low Pressure Micro-resistojet (LPM). Both concepts are developed at TU Delft and are designed to...

In microfluidics, typical laboratory processes can be condensed to a miniature device. This reduces analysis time and required volumes of samples and reagents, increases mobility and flexibility, and is cost effective. In this work, the environmental impacts of three microfluidic devices for glucose detection are assessed using a comparative...

Crystallization is one of the most common separation techniques in chemical industry. Nonetheless, the nucleation step in the crystallization process is little understood. This makes it difficult to gain control over the crystallization process and more specifically crystal properties. Nucleation mechanics is therefore studied thoroughly. Non...

An organ-on-chip (OoC) is a microelectromechanical (MEMS) device that aims to recapitulate in-vitro the physiology of the smallest functional unit of an organ in order to perform drug analysis or study disease models. OoCs are very complex systems that require actuation and sensing capabilities within controlled and delicate environment. The...

Struijk, Victor (author)
Life at low-Reynolds numbers regime is intriguing. Single motile bacteria are known to exhibit erratic behaviour; they swim in what is known as a random walk, alternating between periods of swimming straight and abrupt moments of re-orientation. Yet in dense populations, cells of E.coli have been reported to exhibit weak synchronization and self...

Drug efficacy and side effects are significantly impacted by the first-pass metabolism, a sequence of events that occurs in the stomach and the liver after oral ingestion. Accurate prediction of this mechanism is crucial for a faster and more cost-efficient drug development process. Replicating the first-pass metabolism in vitro using standard...

Fluid flow processes such as drainage and evaporation in porous media are crucial in geological and biological systems. The motion of the displacement front of a moving fluid through multi-phase interfaces is often associated with abrupt mechanical energy release, detectable as acoustic emissions (AEs). The exact origin of these pulses and...

A low-cost glass-based microfluidic flow cell with a piezo actuator is built using off-the-shelf parts (total cost €9 per device) to apply acoustophoretic force on polystyrene micro-beads. The main challenge in the fabrication of these devices was to ensure their leak tightness, which we solved using double-sided tape and nail polish. Beads...

Two decades of research on droplet formation in microchannels have led to the widely accepted view that droplets form through the squeezing mechanism when interfacial forces dominate over viscous forces. The initially surprising finding that the volume of the droplets is insensitive to the relative importance of these two forces is nowadays...
