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.

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.

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.
