Nano-Scale Hyperspectral Imaging
CytoViva’s Hyperspectral Imaging Technology was specifically designed to provide quantitative spectral analysis of nanoscale materials (nanoparticles, virus, bacteria, liposomes etc.) imaged with the patented CytoViva darkfield-based microscope technology. This includes the ability to map the presence and location of nanomaterials in a wide range of environments. In addition, hyperspectral imaging is used to characterize unique surface chemistry and functional groups added to nanomaterials. Finally, certain biologicals such as bacteria and pathogens can be spectrally characterized and mapped in tissue and other environments. In all examples, no special fluorescent markers are required.
CytoViva’s hyperspectral imaging capability can also support other standard microscope imaging techniques such as reflected light, fluorescence and transmitted light brightfield. In addition, it can support more macro level image analysis.
A new option is the analysis in the SWIR range (900-1700nm). Typical applications for this are carbon nanotubes and thin films on Si Wafers.
Recently published (February 2016) results in Microscopy Research and Technique www.ncbi.nlm.nih.gov/pubmed/26864497 have demonstrated the accuracy of CytoViva’s enhanced darkfield hyperspectral microscopy, by comparing its performance against scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM-EDS) and Raman spectroscopy. This work was conducted by the Brenner Research Group at State University of New York (SUNY) Polytechnic Institute, Colleges of Nanoscale Science and Engineering.
