Resonant Surface-Enhanced Infrared Spectroscopy (Resonant SEIRA) Using Metal Nanoantennas

August 01, 2021

Resonant SEIRA overcomes the limitations of traditional Fourier transform infrared (FT-IR) spectroscopy for minute sample sizes of relatively low absorptivity. Frank Neubrech of Heidelberg University is exploring resonant SEIRA in applications such as monitoring dynamic processes and hyperspectral infrared chemical imaging.

The Characterization of Zeolite Crystals Using Raman Spectroscopy

March 09, 2020

Recently, we spoke to Scott M. Auerbach a professor of chemistry and chemical engineering at the University of Massachusetts Amherst, about his work in the use of Raman spectroscopy for zeolite structure characterization, which has focused on a collection of nine all-silica zeolites.

Using Nanopore Sensors to Analyze and Characterize Heparin and Other Therapeutic Polysaccharides

February 05, 2020

Solid-state silicon nitride (SiNx) nanopore sensors can be used to analyze natural and synthetic oligosaccharides and polysaccharides like the anticoagulant drug heparin. These sensors are providing an understanding of nanopore electrokinetics-mechanisms important for capillary electrophoresis with often outsized importance on the nanoscale. Recent work in the use of nanopores is providing a platform for the development of new assays applicable to clinical analysis for a variety of therapeutic molecules. Nanopore sensors can be combined with spectroscopic techniques for multiple analytical applications. Recently, we spoke to Jason R. Dwyer, of the University of Rhode Island (USA) and a FACSS Innovation Award winner from the 2019 SciX conference, regarding his work in this field. This interview is part of a series of interviews with the winners of awards that are presented at the SciX conference.

December 01, 2019

This interview with Jake Shelley, the 2020 winner of the Emerging Leader in Atomic Spectroscopy award, describes his work on the underlying science behind desorption and ionization phenomena, as well as the issues associated with sample matrix effects inherent for plasma-based mass spectrometry.

Gary M. Hieftje’s Legacy: Fifty Years of Scientific Contributions

December 01, 2019

A famous and admired professor of analytical chemistry, Gary M. Hieftje, is officially retiring. He has been a prominent faculty member at Indiana University for 50 years, and a beloved mentor, colleague, and friend to many. In this special feature, we take a look at his many contributions, and his broad impact on the field.
