Imagine unlocking the secrets of the human body and the environment with tools so precise they can pinpoint molecules in a drop of blood – that's the thrilling frontier David S. Hage is exploring in separation science and bioanalysis! But here's where it gets controversial: as these technologies race forward, are we risking privacy invasions or ethical dilemmas in how deeply we analyze biological systems? Dive in to discover more.
David S. Hage, a leading voice in the field, chats with LCGC International about the cutting-edge trends and hot topics in separation science and bioanalysis that are fueling breakthroughs in analytical chemistry. These areas are all about separating and studying complex mixtures – think of it as sorting tiny particles in a crowded room to find exactly what you're looking for, which helps us understand everything from disease markers to environmental pollutants. For beginners, separation science is like a high-tech detective tool that isolates specific substances from messy samples, while bioanalysis applies this to biological systems, such as analyzing proteins or drugs in our bodies. And this is the part most people miss: these fields are evolving at lightning speed, thanks to fresh technologies, creative approaches, and the growing need to tackle tricky analytical puzzles.
In this insightful interview, David S. Hage – the James Hewett University Professor at the University of Nebraska–Lincoln and the proud recipient of the 2025 Eastern Analytical Symposium (EAS) Award for Outstanding Achievement in Separation Science – offers his expert take on the developments steering the future of analytical techniques. His lab is at the heart of innovation, focusing on enhancing affinity chromatography (a method that uses specific attractions to grab and separate molecules, like a magnet for certain metals), capillary electrophoresis (a technique that separates charged particles in a tiny tube using electric fields), and blended analytical systems to handle tough biological and environmental samples.
Hage's team dives into four linked research domains that push the boundaries:
- Chromatographic immunoassays, which merge the pinpoint accuracy of immune reactions with classic separation methods to detect substances with incredible specificity – for example, identifying a rare biomarker in a patient's blood sample.
- Investigations into biological interactions via affinity techniques, measuring how molecules bind together, including their speed and ratios, which is crucial for drug development.
- Cutting-edge supports and attachment strategies to make these tools tougher, more selective, and better performing, ensuring reliable results even in harsh conditions.
- Small-scale and microfluidic setups for quick analyses, ideal for tailoring medical treatments to individuals or monitoring pollution on the spot.
With over 350 scholarly articles, critiques, and book sections under his belt – including the go-to Handbook of Affinity Chromatography – Hage also serves as the Editor-in-Chief of the Journal of Chromatography B. He's a Fellow of the American Association for the Advancement of Science and part of the National Academy of Clinical Biochemistry, showcasing his stature in the scientific community.
His groundbreaking work has earned him a slew of accolades, from the ACS Chromatography Award and the ISMR/Pierce Award in Affinity Technology to the Eastern Analytical Symposium Award for Separation Science and the AACC Young Investigator Award, plus university honors like the University of Nebraska’s Outstanding Research and Creative Activity Award.
Beyond research, Hage is a passionate teacher and guide, leading the writing of textbooks like Analytical Chemistry and Quantitative Analysis, and contributing to numerous reference works in the field. His dedication to education has been celebrated with awards such as the College Distinguished Teaching Award, the Excellence in Graduate Education Award, the Lily Sands Legacy Award, and global nods from the IFCC and AACC for his stellar contributions to teaching.
But here's where it gets controversial: As we develop faster, miniaturized tools for personalized medicine, could this lead to over-reliance on data that blurs the line between science and surveillance? Or, in environmental applications, might these advancements reveal uncomfortable truths about pollution that challenge industry practices? What do you think – is the rapid pace of innovation in bioanalysis a game-changer for health and the planet, or does it raise red flags about ethics and equity? Share your thoughts in the comments; we'd love to hear agreements, disagreements, or fresh perspectives!
