Chaotic mixing using source-sink microfluidic flows in a PDMS chip

Martinus Adela Maria Gijs, Abdeljalil Sayah, Caroline Vandevyver, Ata Tuna Ciftlik, Venkataragavalu Sivagnanam, Hüseyin Cumhur Tekin

We present an active fixed-volume mixer based on the creation of multiple source–sink microfluidic flows in a polydimethylsiloxane (PDMS) chip without the need of external or internal pumps. To do so, four different pressure-controlled actuation chambers a ...

Ultra-thick micro-optical components using the PRISM photosensitive flexopolymer

Martinus Adela Maria Gijs, Virendra Kumar Parashar, Abdeljalil Sayah, Venkataragavalu Sivagnanam

We present the photosensitive flexopolymer PRISM as a new promising material for the realization of thick optical components. The PRISM flexopolymer can be directly polymerized using conventional UV exposure and is simply developed in a water-based solutio ...

Understanding the mixing process in 3D microfluidic nozzle/diffuser systems: simulations and experiments

Martinus Adela Maria Gijs, Abdeljalil Sayah

We characterise computationally and experimentally a three-dimensional (3D) microfluidic passive mixer for various Reynolds numbers ranging from 1 to 100, corresponding to primary flow rates of 10-870 mu l min(-1). The 3D mixing channel is composed of mult ...

Bead-based single protein micro-array realized through electrostatic self-assembly of carboxylated beads

Martinus Adela Maria Gijs, Abdeljalil Sayah, Venkataragavalu Sivagnanam

We report here a simple method, based on electrostatic self-assembly, for realizing bead-based single protein micro-arrays. We generate positively charged surface micro-patterns on a glass substrate and use them as template for adsorbing negatively-charged ...

Fabrication of microfluidic mixers with varying topography in glass using the powder blasting process

Martinus Adela Maria Gijs, Virendra Kumar Parashar, Abdeljalil Sayah

The powder-blasting method is used to fabricate structures with a three-dimensional topography in glass using elastomeric masks. The relation between the mask opening width and the erosion depth is exploited to fabricate microstructures with varying depth ...

Self-assembled melamine microlens arrays for immunofluorescence enhancement

Martinus Adela Maria Gijs, Abdeljalil Sayah, Hüseyin Cumhur Tekin, Hui Yang

Self-assembled dielectric microlenses are used for focusing of the fluorescent signal emitted from a surface-based immunoassay, performed on silane micropatterns as assay substrates, to enhance the detection signal. In our model system, a fluorescent immun ...

Micropatterning of protein-functionalized magnetic beads on glass using electrostatic self-assembly

Martinus Adela Maria Gijs, Abdeljalil Sayah, Caroline Vandevyver, Venkataragavalu Sivagnanam

We demonstrate a simple and fast method for self-assembly-driven micropatterning of protein functionalized magnetic beads on glass. We use positively charged aminosilane micro-patterns as template for selective immobilization of streptavidin-coated beads b ...
