Microfluidic array cytometer based on refractive optical tweezers for parallel trapping, imaging and sorting of individual cells

René Salathé, Horst Vogel, Fabrice Merenda, Joachim Piguet, Michael Werner

Analysis of genetic and functional variability in populations of living cells requires experimental techniques capable of monitoring cellular processes such as cell signaling of many single cells in parallel while offering the possibility to sort interesti ...

GOLD MEMBRANES WITH LARGE ARRAYS OF SUB-µm HOLES FABRICATED BY WAFER-SCALE NANOSPHERE LITHOGRAPHY

Jürgen Brugger, Harry Heinzelmann, Mona Julia Katharina Klein, Raphaël Pugin

Gold membranes with large arrays of sub-µm holes were fabricated and optically characterized. The fabrication is a combination of a bottom-up, self-assembly based patterning technique, Nanosphere Lithography (NSL), and standard microfabrication. This was a ...

Monolithic Silicon Chip for Immunofluorescence Detection on Single Magnetic Beads

Edoardo Charbon, Martinus Gijs, Ulrike Lehmann, Caroline Vandevyver, Emile Dupont

While fluorescence detection is widely used for bioassays owing to its high sensitivity, a complete fluorescent microscopy setup, comprised of a light source, optical filters, a microscope body, and a camera, still is bulky equipment, compromising its use ...

Magneto-microfluidic three-dimensional focusing of magnetic particles

Martinus Gijs, Thomas Lehnert, 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 ...

Monitoring ligand–receptor interactions by photonic force microscopy

László Forró, Flavio Maurizio Mor, Sylvia Jeney

We introduce a method for the acquisition of single molecule force measurements of ligand-receptor interactions using the photonic force microscope (PFM). Biotin-functionalized beads, manipulated with an optical trap, and a streptavidin-functionalized cove ...

Three-dimensional force measurements in optical tweezers formed with high-NA micromirrors

László Forró, René Salathé, Fabrice Merenda, Sylvia Jeney, Mathieu Grossenbacher

The three-dimensional trap stiffness of optical tweezers formed with high-NA micromirrors is investigated by back-focal-plane interferometry and power spectrum analysis. Normalized stiffness values of kappa(xy)/P-trap =1.2(mu N/m)/mW and kappa(z)/P-trap = ...

Comparison between various types of multiple optical tweezers

René Salathé, Fabrice Merenda, Johann Rohner, Jean-Marc Fournier

Many types of optical tweezers arrays have been proposed and developed for use in conjunction with microfluidics for bio-chemical essays. Trap arrays rely on different methods allowing various degrees of flexibility and relative trapping efficiencies. Amon ...
