Magnetic particle dosing and size separation in a microfluidic channel

Thomas Lehnert, Martinus Gijs, Yves Moser, Rana Afshar Ghasemlouy

Separation of functional magnetic particles or magnetically labeled entities is a key feature for bioanalytical or biomedical applications and therefore also an important component of lab-on-a-chip devices for biological applications. We present a novel in ...

Three-Dimensional Magnetic Focusing of Superparamagnetic Beads for On-Chip Agglutination Assays

Thomas Lehnert, Martinus Gijs, Yves Moser, Rana Afshar Ghasemlouy

We present a new method for three-dimensional (3D) magnetic focusing of magnetic microparticles in a microfluidic system. On-chip magnetic particle manipulation in themicrochannel is achieved by a high-gradientmagnetic field generated by means of a microma ...

Suspended SU-8 structures for monolithic microfluidic channels

Thomas Lehnert, Martinus Gijs, Sébastien Jiguet, Yves Moser, Riccardo Forti

SU-8 photoresist is commonly used in the field of microfabrication as structural material or for molding of microfluidic devices. One major limitation, however, is the difficulty to process partially freestanding SU-8 structures or monolithic closed caviti ...

Dynamic Actuation of Magnetic Beads for Immunoassays on-chip

Yves Moser

This thesis was carried out in the frame of the European project DetectHIV aiming the development of a new biosensor platform for the highly sensitive detection of the HIV capsid protein p24. We explore the implementation of a magnetic bead-based lab-on-a- ...

Magneto-microfluidic three-dimensional focusing of magnetic particles

Thomas Lehnert, Martinus Gijs, Yves Moser, Rana Afshar Ghasemlouy

We present a method for magneto-microfluidic three-dimensional focusing of magnetic microparticles from a dense plug into a single streamline with longitudinal inter-particle spacing. Plug formation on-chip is induced by a high-gradient magnetic field gene ...

Quadrupolar magnetic actuation of superparamagnetic particles for enhanced microfluidic perfusion

Thomas Lehnert, Martinus Gijs, Yves Moser

We report on the magnetic actuation of superparamagnetic particles in a microfluidic channel. The formation of a highly confined and dynamic plug of particles extending over the cross section of the microchannel is enabled by superposing a static and a tim ...

On-chip immuno-agglutination assay with analyte capture by dynamic manipulation of superparamagnetic beads

Martinus Gijs, Yves Moser

Magnetic bead-based lab-on-a-chip systems offer significant advantages compared to more conventional systems, mainly through the possibility of controlled manipulation of the magnetic carriers on-chip. In particular, microfluidic immunoassays using functio ...
