Congratulations to Adam and Wilfred!

Adam has successfully defended his Ph.D and has graduated this past June! He will be leaving us to work in industry. Wilfred has also successfully defended his master’s thesis and graduated this past June as well! He will be leaving us to further his education in a purist of a Ph. D. Good luck gentlemen and best of luck in your future endeavors!

3rd Annual CBC Research Symposium

Members of the Heien lab presented their research at the annual department symposium. Kate gave an oral presentation while the rest of the lab presented posters. Drew and Adam won best poster presentation, and James won the best visualization “eye candy” poster award!

Check out some photos taken by the department here!

News: Heien Lab has paper accepted into Analytical Chemistry

Richard F. Vreeland, Nicholas D. Laude, Sean Lambert, and Dr. Michael L. Heien have published  a new peer-reviewed publication. The publication outlines a new technique our lab has developed to etch thin films of conductive polymers for the fabrication of microelectrodes. This technique is an alternative to reactive ion etching, and offers similar capability while only costing the user about $100 (for a microwave from Home Depot) and is entirely benchtop. The microwave etch is used to fabricate a microchip electrophoresis platform where neurotransmitters are separated and detected. The sensor is characterized and compared to more common materials like carbon. Congratulations!

News: Heien Lab has paper accepted into Analytical Chemistry

Christopher W. Atcherley, Nicholas D. Laude, Katherine L. Parent, and Dr. Michael L. Heien have published  a new peer-reviewed publication. The publication outlines a new technique our lab has developed to measure the tonic or “basal” concentration of dopamine in vivo. The technique exploits the strong adsorption interaction between dopamine and carbon fiber microelectrodes. Characterization and optimization of the technique is described. Congratulations!

News: Heien Lab has paper accepted into Analytical Chemistry

Christopher W. Atcherley, Richard F. Vreeland, Esther Sanchez-Gomez, Dr. Eric B. Monroe  and Dr. Michael L. Heien have published  a new peer-reviewed publication. The publication outlines the utility of  a zero-phase filter for fast scan cyclic voltammetry experiments to  avoid traditional filtering artifacts, as well as the filter’s utility in filtering amperometric data from PC12 cell exocytosis. The authors are also sharing their program on this website, in the software section. Congratulations!

News: Christopher W. Atcherley presents in-vivo tonic and phasic measurements of dopamine

Christopher W. Atcherley gave a presentation to the University of Arizona Chemistry and Biochemistry Department on April 26th, 2013, detailing some of his work in Quantifying tonic and phasic neurotransmission with fast-scan cyclic voltammetry. Christopher was selected as this year’s David E. O’Brien Graduate Fellow, and will go on to present his work at a Gordon Conference later this year. Congratulations Chris!
