Automated image analysis uses finely tuned software to extract data from digital images. Algorithms recognize specific shapes and patterns in the images and gather quantitative information that is then used for further data analysis. The pharmaceutical and biological research industries have benefitted greatly from this technology, which allows researchers to analyze hundreds—if not thousands—of samples…
Are you an assiduous biologist who prefers label-free imaging methods for biological samples analysis? Raman spectroscopy offers you a wonderland of imaging technique with unlimited benefits. To start with, Raman Spectroscopy is a spectroscopic technique based on inelastic scattering of monochromatic light usually from a laser in the visible or near infra-red part of electromagnetic…
