Label-Free Long-Term Methods for Live Cell Imaging of Neurons: New Opportunities

Georg Fantner, Zahra Ayar Dulabi, Samuel Mendes Leitão

Time-lapse light microscopy combined with in vitro neuronal cultures has provided a significant contribution to the field of Developmental Neuroscience. The establishment of the neuronal polarity, i.e., formation of axons and dendrites, key structures resp ...

Targeted search for scaling genes reveals matrix metalloproteinase 3 as a scaler of the dorsal-ventral pattern in Xenopus laevis embryos

Daria Korotkova

How embryos scale patterning according to size is still not fully understood. Through in silico screening and analysis of reaction-diffusion systems that could be responsible for scaling, we predicted the existence of genes whose expression is sensitive to ...

Subcellular Chemical Imaging: New Avenues in Cell Biology

Melissa Kathleen Passarelli

To better understand the physiology and acclimation capability of the cell, one of the great challenges of the future is to access the interior of a cell and unveil its chemical landscape (composition and distribution of elements and molecules). Chemical i ...

Recent advances with optical upconverters made from all-organic and hybrid materials

Roland Hany, Karen Verena Strassel

The growing interest in near-infrared (NIR) imaging is explained by the increasing number of applications in this spectral range, which includes process monitoring and medical imaging. NIR-to-visible optical upconverters made by integrating a NIR photosens ...

Combined use of airborne laser scanning and hyperspectral imaging for forest inventories

Matthew Josef Parkan

The thesis presented hereby proposes as a general objective the estimation of forest inventory parameters (e.g. trunk location, height, basal area, crown area, species, etc..) from the combination of Airborne Laser Scanning (ALS) and Hyperspectal Imaging ( ...

A microfluidic cell-trapping device to study dynamic host-microbe interactions at the single-cell level

John McKinney, Matthieu Jean-Hubert Delincé, Chiara Toniolo

Single-cell imaging of host-microbe interactions over time is impeded by cellular motility because the cells under scrutiny tend to migrate out of the imaging field. To overcome this technical challenge, we developed a microfluidic platform for imaging hun ...

8-Channel Single Embryo Pipette For Accurate C-Elegans Bioassays

Martinus Gijs, Thomas Lehnert, Li Dong, Jingwei Zhang

The nematode Caenorhabditis elegans (C. elegans) is a powerful model organism for addressing fundamental biological questions related to human disease and aging. Accurate control of the number of worms is a primary step for quantitative biological or bioch ...

The multi-spectral imaging diagnostic

Basil Duval, Christian Gabriel Theiler, Yanis Andrebe, Kevin Henricus Annemarie Verhaegh, Mirko Wensing

The Multi-Spectral Imaging system is a new diagnostic that captures simultaneous spectrally filtered images from a common line of sight while maintaining a large etendue and high throughput. Imaging several atomic line intensities simultaneously may enable ...
