As part our Analytical Methods’ special issue on, “Microfluidic Systems with Societal Impact,” we would like to take the time to honor and celebrate the 60th birthday of two pioneers of microfluidics: Professor Susan Lunte and Professor James Landers. We would like to thank those that contributed to this special issue, in part, to honor Sue and James.

Susan Lunte (Sue to those that know her well) is currently the Ralph N. Adams Distinguished Professor of Chemistry and Pharmaceutical Chemistry and Director of the Adams Institute for Bioanalytical Chemistry at the University of Kansas. She is also the former Editor-in-Chief of Analytical Methods. Sue and her group have focused on the development and application of capillary and microfluidic systems that enable quantitation of important markers in biological systems. She has published over 150 papers and 15 book chapters in this area. Early in her career, her research focused on capillary electrophoresis, with many papers detailing new electrochemical detection schemes for this then new separation method.1–3 Her group quickly realized that the small sample volume requirements of CE could be used to make high temporal resolution measurements from microdialysis sampling, with several key papers of continuously monitoring in vivo systems with microdialysis and CE.4,5 Around the year 2000, her group started to explore the use of microchip-based analysis systems, with several demonstrations of electrochemical detection for microchip electrophoresis.6,7 This was followed by key papers describing the integration of microdialysis sampling with microchip-based analysis,8,9 including a “Lab-on-a-Sheep” system.10 More recent work includes using microfluidics to investigate the production of reactive oxygen species in cellular systems.11,12 These achievements have been recognized with several awards including an AAPS Research Achievement Award, the Purdue University Chemistry Department Outstanding Alumnus Award and, most recently, the ANACHEM Award, which will be awarded at SciX 2018.

While this is not an exhaustive overview of her body of work, it is clear that she has made a large impact on the fields of bioanalytical chemistry and biomedical analysis. Because of this impact, it is quite fitting to recognize her and her pivotal work in this special issue of Microfluidic Systems with Societal Impact. All four authors of this editorial can also attest to what a great mentor Sue has been to junior scientists over the years. This includes undergraduate and graduate students, post-docs (Scott Martin being one of many she mentored), visiting scientists from Brazil and Ireland (Fiona Regan being one example), and junior faculty members (such as Chris Easley and Mike Roper). We all have benefited from her advice, promotion, thoughtfulness and friendship over the years.

James P. Landers is the Commonwealth Professor in the Departments of Chemistry, Mechanical Engineering, and Pathology at the University of Virginia (UVA). He is also the Director of the Center for Nano-Biosystems Integration, a member of the UVA Cancer Center, a Jefferson Scholar Faculty Fellow, and serves as an Editor for Analytica Chimica Acta. For his pioneering and continuing work toward scientific advancements, education, and training in the area of microfluidic devices with high societal impact, this editorial also honors Professor Landers on the occasion of his 60th birthday.

James began his unique research style as he launched and directed the Mayo Clinic’s Clinical Capillary Electrophoresis (CE) Facility in the Department of Laboratory Medicine and Pathology, developing clinical assays based on CE technology. Afterwards, he began his independent faculty career at the University of Pittsburgh before moving to UVA in 1999. Throughout his career, he has been an innovator in the field of microfluidic system development. Notable early achievements include his pioneering work in rapid, on-chip DNA amplification,13 on-chip separations for clinical applications,14 and on-chip solid-phase extraction of DNA from body fluids.15 Using this groundwork, his group (incl. Easley and Roper) was one of the first to demonstrate a fully-integrated lab-on-a-chip system capable of DNA extraction, amplification, and separation directly from blood or nasal aspirates.16 He has translated this and similar systems to the forensic community for rapid analysis of fluids and tissues present at crime scenes.17,18 Lately, his group has developed unique fluidic control strategies,19,20 a novel “pinwheel” approach for simplified nucleic acid detection,21 centrifugal microfluidics,22 and inexpensive device fabrication methodology.22,23 James has authored more than 250 papers and has edited three editions of the CRC Press Handbook of Capillary Electrophoresis,24 with the latest edition including microchip electrophoresis and associated microtechniques. He has mentored numerous undergraduate researchers, PhD students (such as Chris Easley), and postdocs (such as Mike Roper); and many have gone on to have successful careers in the sciences. Those who have worked closely with him will attest that James has a unique ability to see the big picture, particularly in the areas of clinical diagnostics and forensic analysis, and how research can benefit these fields. As members of his laboratory push forward with sample preparation, separations, and analysis at the microscale, they have the rare advantage of an open view to their end application due to James’s mentoring.

On a personal note, James has always been a supportive mentor who welcomes everyone in his laboratory by hosting BBQs on his back porch, playing hockey games with them in the basement of his home, and regaling them with stories of growing up in Canada. He is warm-hearted and will always do whatever he can to help out his students and members of his lab, current and former.

We wish both Sue and James Happy Birthday and look forward to their scientific contributions for many years to come. We wish them continued success in the lab and in life!
