Photonic Nanojet Array for Fast Detection of Single Nanoparticles in a Flow

Martinus Gijs, Matteo Cornaglia, Hui Yang

We detect by optical microscopy Au and fluorescent nanopartides (NPs) during their motion in water based medium, using an array of dielectric microspheres that are patterned in a microwell array template. The Microspheres act as lenses focusing the light o ...

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 ...

Fast detection of single nanoparticles in a microfluidic channel by a microlens array in combination with a conventional optical microscope

Martinus Gijs, Matteo Cornaglia, Hui Yang

We present the use of a microlens array in combination with a conventional optical microscope set-up for the detection of single nanoparticles (NPs) in fluid medium. Optically transparent dielectric microspheres are patterned in a microfabricated well arra ...

Programming and use of Parylene C fluorescence as a quantitative on-chip reference

Martinus Gijs, Diego Gabriel Dupouy, Ata Tuna Ciftlik, Joan Teixidor

A large number of lab-on-a-chip applications use fluorescence for quantifying biological entities. In such applications, incorporation of a stable on-chip fluorescent reference source would be highly desirable in order to compensate for instrumental parame ...

Automated Biomanipulation of Single Cells using Magnetic Microrobots

Mahmut Selman Sakar

Transport of individual cells or chemical payloads on a subcellular scale is an enabling tool for the study of cellular com- munication, cell migration, and other localized phenomena. We present a magnetically actuated robotic system capable of fully autom ...

Photocatalytic Nanolithography of Self-Assembled Monolayers and Proteins

Esther Amstad

Self-assembled monolayers of alkylthiolates on gold and alkylsilanes on silicon dioxide have been patterned photocatalytically on sub-100 nm length-scales using both apertured near-field and apertureless methods. Apertured lithography was carried out by me ...

Full field vertical scanning in short coherence digital holographic microscope

Christian Depeursinge, Christophe Moser, Etienne Cuche, Frédéric Montfort

In Digital holography Microscopes (DHM) implemented in the so-called "off axis" configuration, the object and reference wave fronts are not co-planar but form an angle of a few degrees. This results into two main drawbacks. First, the contrast of the inter ...

Empowering Low-Cost CMOS Cameras by Image Processing to Reach Comparable Results with Costly CCDs

Giovanni De Micheli, Sandro Carrara, Yusuf Leblebici, Gözen Köklü, Julien Michel Ghaye

Despite the huge research effort to improve the performance of the complementary metal oxide semiconductor (CMOS) image sensors, charge-coupled devices (CCDs) still dominate the cell biology-related conventional fluorescence microscopic imaging market wher ...

Biophotonic tool for sensing the dynamics of H2O2 extracellular release in stressed cells

Olivier Martin, Christian Santschi, Shourya Dutta Gupta

Hydrogen peroxide (H2O2) is known to play a multifaceted role in cell physiology mechanisms involving oxidative stress and intracellular signal transduction. Therefore, the development of analytical tools providing information on the dynamics of H2O2 gener ...
