Novel cell culture platforms, with more physiological surface roughness, require different technologies capable of precisely micropattern substrates. 3D printing offers a considerable accuracy and user-friendly procedures. For its part, pulsed laser ablation proves to be a versatile technology to perform detailed surface micropatterning. In this work, both technologies were combined to easily fabricate a versatile PDMS multi-well platform for performing cellular studies on a micropatterned biocompatible surface.

Fluorescence for non-contact detection of salmon lice in fish farms
Kari Anne Hestnes Bakke, Jon Tschudi, Trine Kirkhus
This work presents a promising method for automatic non-contact detection and counting of salmon lice infested on salmon in an aquacultural farm setting. The method uses fluorescence in the visual part of spectrum to enhance the contrast between fish skin and lice. The wavelengths used are compatible with an underwater measurement system.

We demonstrate that direct imaging is a powerful tool for the detection and recognition of microplastics in water, even in case of complex matrices. We use a commercial high-resolution imagining device (FS5, Valmet Oy.) originally developed for the observation of wood fibres in papermill water systems. We show how to discriminate microplastics from other particles in suspension in real water samples. We show differences between several common plastic types in homemade samples.

Quadrics for structuring invariant space-time wave packets

Laboratoire ICB - CNRS, France
We provide a general approach for structuring invariant 3D+1 optical wave packets in both bulk and structured dispersive media, through a simple engineering of phase-matched space-time frequencies on quadric surfaces.

Carbon dioxide measurement is an important endeavor in many industries such as food packaging, grain storage and health industry. This work presents a reversible, plug and play and low-cost colorimetric CO2 sensor calibrated in a proper concentration ranging from 1% to 3% of CO2. The sensor showed potential for improvement to increase resolution, for measuring lower CO2 concentrations and for more accurate readings.

Automation strategies and machine learning algorithms towards real-time identification of optically trapped particles

To automatically trap, manipulate and probe physical properties of micron-sized particles is a step of paramount importance for the development of intelligent and integrated optomicrofluidic devices. In this work, we aim at
implementing an automatic classifier of micro-particles immersed in a fluid based on the concept of optical tweezers. We describe the automation steps of an experimental setup together with the implemented classification models using the forward scattered signal. The results show satisfactory accuracy around 80% for the identification of the type and size of particles using signals of 250 milliseconds of duration, which paves the path for future improvements towards real-time analysis of the trapped specimens.
