In a previous paper, 1 we proposed an optofluidic modulator based on peristaltic flow. A microchannel made of polydimethylsiloxane is filled with nematic liquid crystal molecules that align homeotropically in the steady state. Once we apply a periodic peri ...
A sensitive chemiluminescence (CL)-based immunoassay technique based on both dipstick and flow injection analytical formats is reported for the detection of atrazine. In the dipstick-based immunoassay technique, antibody (anti-atrazine) was first immobiliz ...
We present a simple and easy to handle PDMS microfluidic device for neuronal cell culture studies in three-dimensional hydrogel scaffolds. The hydrogel is structured in parallel layers to reconstruct cell layers close to the natural environment. Dissociate ...
With a growing number of cell-based biotechnological applications, there is a need for particle separation systems capable of multiparameter separations at high purity and throughput, beyond what is presently offered by traditional methods including fluore ...
The dynamics of formation of solute peaks in microfluidic systems are investigated by computer simulation. A finite-element numerical procedure is applied to analyze the diffusion- and flow-controlled concentration dispersion in a 40 μm-high rectangular fl ...
We present an optofluidic chip with integrated polymer interferometers for measuring both the microfluidic air pressure and flow rate. The chip contains a microfluidic circuit and optical cavities on a polymer which was defined by soft lithography. The pre ...
This thesis reports on the development of technologies and methods for a microfiuidic device for continuous pressure-driven flow-injection analysis. Chip based, pressure-driven liquid chromatographic (LC) systems are often avoided due to the difficulties e ...
Magnetic microparticles and their application in bioanalytical microfluidic systems have been steadily gaining interest in recent years. This progress is fueled by the comparatively large and long range magnetic forces that can be obtained independently of ...
Since the introduction of the of Micro Total Analysis Systems concept in 1990, important progress in microfluidic analytical systems has been realized. In many cases, microfluidic systems have shown improved analytical performances over classical methods, ...
This thesis reports on the integration of continuous-flow cell separation method for lab-on-a-chip applications. Cell separation methods are widely used in biology to prepare samples prior to analysis. There is a need for a highly sensitive separation meth ...
