Hyperspectral microscopy- applications of hyperspectral imaging techniques in different fields of science: a review of recent advances

Abstract

AbstractHyperspectral imaging is a powerful analytical technique that is drawing more attention among the different disciplines due to its feasibility for in situ applications on imaging of living organisms. In this review article, we summarize the development and implementation of this technique in the different fields of science. It is important to acknowledge that the hyperspectral microscope, a specialized imaging tool, combines the power of microscopy with the ability to capture detailed spectral information about the sample studied. Unlike traditional microscopes, which only capture spatial information about a sample, hyperspectral microscopes also capture spectral data from each spatial point, resulting in a 3D data cube. The latest applications have been studied and described, including examples from the environmental and medical field. The broad possibilities related to hyperspectral microscopy were discussed and highlighted showing successful results. Hyperspectral microscopy is a revolutionary and reliable technique in the world of characterizing analytical tools.Keywords: Hyperspectral imagingenhanced dark-field hyperspectral microscopynondestructive techniquedarkfield hyperspectral microscopynanoparticles AcknowledgmentThe authors acknowledge Dr. Jose A.
