X-ray photoelectron spectroscopy (XPS) is the most widely used and important method for chemical analysis of surfaces. The technique is surface sensitive, the information depth for standard Al X-ray excitation being 5 – 10 nm.
In this interview, Wen Hwa Lee, CEO, and Chief Scientist at Action Against Age-Related Macular Degeneration (AAAMD), offers an enlightening perspective on merging AI with ophthalmology to forge new paths in healthcare and drug discovery.
Aristotle’s postulate that “nature abhors a vacuum” could be used to explain why X-ray photoelectron spectroscopy (XPS) has not found routine application in the analysis of biological samples.
In recent years, the fastest growing segment of the electron microscopy market has been Table-top SEMs. As these tools continue to gain wide acceptance, users are often required to image non-conductive samples.
This article outlines the use of Deep UV resonant Raman spectroscopy to analyze molecular compounds with high specificity.
