New Publication!

We are happy to announce that our work on using deep eutectic solvents has now been published in Analytical Chemistry: https://pubs.acs.org/doi/10.1021/acs.analchem.2c03980 This work was done by Jessica Torres, a doctoral student in the lab, along with Karen Campos and undergraduate student currently in the lab.

Fluorescently labelling amino acids in DES

This work explores how one can do fluorescent labelling in deep eutectic solvents (DES). Our goal for this work is to apply DES to the analysis of amino acids in the search for evidence of past extraterrestrial life. But the implications of being able to do the direct labelling of analytes in a DES mean that those solvents could be useful in more sample preparation methods and still allow for the routine labelling reactions to be undertaken

HPLC 2022 Poster Award

Congratulations to Jessica and Karen for winning one of the HPLC 2022 Best Poster awards for their work on “Novel fluorescent labelling of amino acids for detection of past life via CE-LIF“.

Oops, we were back at the lab when the awards were announced

We are very excited that they were recognized for this work, particularly given it was a conference on column chromatography, and they are doing capillary electrophoresis based work. We hope to have the paper out for review and publication later this summer.

SDSU 2021 Research Highlights

We’re very proud that Jessica Torres’ research project was featured in the annual compilation of SDSU Research Highlights.

Jessica was awarded a prestigious NASA Fellowship award which will support her research efforts throughout her pursuit of her doctoral degree. Jessica’s project focuses on developing new approaches to searching for chemical traces of past life on rocks on other bodies in our solar system. The challenging project will further enable NASA’s goals of exploring and understanding the conditions for how life can arise in the Universe, and if life has existed elsewhere.

A new toy for the lab!

New CE-LIF Instrument

Thanks to our friends at NASA/JPL we now have a new, powerful, instrument for the lab. Peter Willis’ group kindly donated an older CE-LIF instrument that they were no longer using to us. The instrument will greatly enhance our lab’s capability to do sensitive detection, opening up more avenues of research.
