Fabrication of Electrophoretic Microdevices for Fluorescence Detection: An Interview with AES Lifetime Achievement Award Winner James P. Landers

By John Chasse

September 29th 2023

The AES Lifetime Achievement Award is given for exceptional career contributions to the fields of electrophoresis, electrokinetics, and related areas. This year’s recipient, James Landers of the University of Virginia, recently published (along with his colleagues) a paper illustrating a technique for fabricating electrophoretic microdevices for fluorescence detection.

Quantum Cascade Lasers for Infrared Spectroscopy: Theory, State of the Art, and Applications

April 1st 2013Mid-infrared quantum cascade lasers, recently developed and commercialized, have unique properties that advance the analytical capabilities of IR spectroscopy in many ways. Bernhard Lendl of Vienna University of Technology in Austria explains these developments.

Resolution in Mid-Infrared Imaging: The Theory

November 11th 2011The field of mid-infrared (mid-IR) imaging has made significant developments in recent years, but the theory has not kept pace. Rohit Bhargava, an associate professor of engineering at the University of Illinois at Urbana-Champaign and the associate director of the University of Illinois Cancer Center, recently undertook studies to address that gap. Spectroscopy spoke to him recently about that work.

Group Theory and Symmetry, Part I: Symmetry Elements

December 1st 2009Group theory is the field of mathematics that includes, among other things, the treatment of symmetry. Well, it turns out that molecules have symmetry, so group theoretical principles can be applied to molecules. Because spectroscopy uses light to probe the properties of molecules, it might not be surprising that group theory has some application to spectroscopy. Here, we start a multipart discussion of symmetry and group theory.

The Role of Naturally Occurring Stable Isotopes in Mass Spectrometry, Part I: The Theory

October 1st 2008In this tutorial, the authors explain how naturally occurring stable isotopes contribute to experimentally determined mass spectra and how this information can be exploited in quantitative experiments, structural elucidation studies, and tracer methodologies. The first installment of this series focuses on the theoretical aspects of stable isotopes and the calculation of their distribution patterns.
