Welcome to the
Microanalytical Chemistry Lab

  • From beer (5%) to whisky (53%) - Simple procedure using UV-LED/hydrogen peroxide opens the door for fast analysis of ethanol by capillary electrophoresis
  • Congratulations to Lauren! Lauren gave the opening remarks at the 2019 College of Science Donor Appreciation day
  • 1-Propanol + UV and hydrogen peroxide. Simple sample pretratement step leads to teh formation of unexpected products
  • If you are planning to get Martian Samples... Check out these flight-compatible methods capable of simultaneously measuring inorganic cations and amino acids in samples of varying salinity by capillary electrophoresis and contactless-conductivity detection
  • Do you know you can use carbon tape as an electrode? Fede, Paige, and Diego demostrated this possibility and used them to analyze beer
  • CE-C4D helps identification of undermedicated patients. New paper describes a simple method to determine topiramate in serum samples
  • Proteins gone wild (on paper). Recent publication explores how proteins adsorb and desorb from cellulose fibers
  • TEDx Cordoba. Many thanks to the organizers for considering our lab for a presentation
  • Monshiners at Clemson. New microfluidic approach to combine electrochemical oxidation, separation, amd detection of primary alcohols
  • New technique yields microfluidics from microscope slides. Using wax as a sacrificial material, channels can be created by laser engraving

Microchips are one of the most promising analytical platforms due to the great advantages with respect to conventional bench-top equipment. Microfluidic devices are able to offer custom design, high throughput, sensitivity, selectivity and portability. In order to achieve a real point-of-care measurement device, simple instrumentation has to be integrated to drive the injection and separation. Electrochemical detection (ECD) methods have been widely applied for the detection of bio-compounds because they are less susceptible to decreases in signal magnitude during miniaturization and are already portable and inexpensive. For these reasons, we are very interested in studying the design, operation and biological applications of microchips and capillary electrophoresis. In addition, we are also interested in the rational design of biosensors. Please visit the associated pages to find more about our projects and most recent publications.

Latest Developments in the Lab

To mitigate the spread of COVID-19, we have developed a color-based assay to estimate the concentration of bleach solutions that only requires a timer.
Congratulations to Lucas Ayres, for receiving one of the 2020 Mandel Fellowships, an award made possible by a gift established in honor of Dr. Frederick Mandel.
Based on the number of downloads and citations, our paper in the Journal of Pharmaceutical Analysis was selected to receive the Silver Award for Top Cited Papers 2020. We wholeheartedly dedicate this award to Dr. Sándor Görög.
Omega cover We published a number of new papers, including Lucas' first cover in Anal Methods! We also got covers in ACS Omega and Soft Matter.
Congrats to Laura McCann, who was selected to receive a 2020 National Science Foundation Graduate Research Fellowship. We are extremely proud of her!
Congrats to Paige and Rafael for their paper describing the possibility to clean serum samples using pyrolyzed cotton balls.
Many thanks to Javier and Diego for including us in the latest paper focused on the catalysis of 5-HMF to form 2,5-furancarboxylic acid.
CDG presented an Editor's collection of articles in RSC Advances focused on CO2 Capture and Reduction.
