Analysis of colonic autofluorescence spectra using multivariate curve resolution alternating least squares

Lina Liu Lina Liu, Changshun Yang, W. Li, Buhong Li et autres

Autofluorescence (AF) spectra of colonic normal and adenocarcinoma tissues are measured under excitation of 337 nm and analyzed by multivariate curve resolution alternating least squares (MCR-ALS) method using non-negativity constraint.Collagen, nicotinamide adenine dinucleotide hydrate (NADH) and elastin are identified as the main …

The Best of Both Worlds: 3D X-ray Microscopy with Ultra-high Resolution and a Large Field of View

W. Li, Jeff Gelb, Yanjing Yang, Yong Guan et autres

3D visualizations of complex structures within various samples have been achieved with high spatial resolution by X‐ray computed nanotomography (nano‐CT). While high spatial resolution generally comes at the expense of field of view (FOV). Here we proposed an approach that stitched several …
