System for optical detection and imaging of sub-diffraction-limited nano-objects

Martinus Gijs, Matteo Cornaglia, Hui Yang

Nano-objects (8) with feature size smaller than the classical Abbe's diffraction limit can be optically detected via a microlens (4) array configured in a miniaturized microfluidic device. A hydrophilic microwell (3) array in a hydrophobic layer (2) is fir ...

Determination of sub-diffraction-limited organelles and biomolecules using microsphere lenses in combination with fluorescence microscopy

Johan Auwerx, Martinus Gijs, Norman Lionel Moullan, Hui Yang

We propose the use of a high-refractive index glass microsphere in combination with a conventional fluorescence microscope for imaging sub-cellular organelles and biomolecules. The microsphere is placed on a sample that is immersed in water, collects the n ...

Towards quantifying effects of refractive index mismatch on PIV results

Karen Ann J Mulleners, Sebastian Kurth

Refractive index matched particle image velocimetry (RIM-PIV) is an elegant method to measure velocity fields around complex geometries and in difficultly accessible areas. The accuracy of RIM-PIV is strongly affected by the quality of refractive index mat ...

Digital confocal microscopy through a multimode fiber

Demetri Psaltis, Christophe Moser, Ioannis Papadopoulos, Damien Claude-Marie Loterie, Salma Farahi, Alexandre Goy

Acquiring high-contrast optical images deep inside biological tissues is still a challenging problem. Confocal microscopy is an important tool for biomedical imaging since it improves image quality by rejecting background signals. However, it suffers from ...

A microfluidic device for longitudinal studies of C.elegans neurodegenerative disease models

Johan Auwerx, Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Laurent Mouchiroud, Govindan Narayanan Krishnamani

We describe a microfluidic device for automated culture and long-term high resolution imaging of Caenorhabditis elegans nematodes, which we specifically employed as model organisms for the analysis of neurodegenerative disease progression. In this platform ...

Confocal polarization imaging in high-numerical-aperture space

Carlos Alberto Macias Romero

In this work we describe theoretical and experimental physical aspects of high-resolution imaging polarimetry and its application to polarization-multiplexed encoding. We theoretically demonstrate that it is possible to resolve the orientation of two fixed ...

Real-time 3D particle manipulation visualized using volume holographic gratings

Zhi Chen, Yves Chevallier

Holographic optical tweezers (HOTs) extend optical trapping into three dimensions. Volume imaging then becomes a concern as trapped objects are easily moved out of focus of the imaging objective lens. Here we demonstrate a three-dimensional real-time inter ...

Lens array by electrostatic patterning of dielectric microspheres in a Parylene-C well template

Martinus Gijs, Matteo Cornaglia, Hui Yang

We present the fabrication of a microlens array which can be integrated into a microfluidic device. In the demonstrated technique, a microwell array is firstly fabricated in a Parylene-C layer by a standard cleanroom process. Afterwards, the optically tran ...
