The success of metabolomics studies depends upon the “fitness” of each biological sample used for analysis: it is critical that metabolite levels reported for a biological sample represent an accurate snapshot of the studied organism’s metabolite profile at time of sample collection. Numerous factors may compromise metabolite sample fitness, including chemical and biological factors which inter...

Vibrational spectroscopy is an attractive modality for the analysis of biological samples, providing a complete non-invasive acquisition of the biochemical fingerprint of the sample. It has been demonstrated that this data provides the means to assay multiple functional responses of a biological system at a spatial resolution as low as a micron within the sample. As the interaction of ionizing ...

Single-pixel detecting is suitable for wavefront reconstruction in some special wavelengths where array detectors are immature or even unavailable and/or under low light conditions. However, most of the demonstrations generally realized by multi-step phase-shifting interferometry with a liquid crystal spatial modulator (LC-SLM) that has slow modulation speed, which limits thus restricting pract...

Diagnostic reports of biological samples submitted from farms are essential to correctly identify any underlying issues in a herd, including disease and improper nutrition. Proper sample collection, handling, storage critical most accurately diagnose health complications or nutritional status. When possible, pigs before they eat, keep tissue frozen, avoid hemolyzed blood samples, minimize trans...
