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.
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
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“.
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.
Our NASA funded research looking for ways to detect chemical traces of past life has gained interest once again. The SDSU NewCenter wrote up a nice piece on the work that Jessica, and now Karen, have been undertaking on this project. The work is also featured on the College of Sciences web page.
It’s great to see the hard work of our research team getting the recognition that they deserve.
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.
We’re very happy to announce that another lab member has joined the IMSD supported team of students in the lab. Adrian now joins Madee and Cat in the program. It’s a great honor to have so many deserving and promising young scientist in the lab, and it is encouraging that the IMSD teams sees, and wants to support, their potential as well.
Last week (Oct. 13-17, 2019) part of the Harrison Lab took a trip up to Palm Springs to present some of their research at the annual SciX conference. SciX is a great conference for the group, both as it is just the right size to have a lot of great science presented and not be overly packed, and also because it serves at the annual meeting for the AES Electrophoresis Society (Chris is currently VP of the society).
So this meeting provided us with a great opportunity to present our latest research, and to catch up with colleagues from other universities and to learn from them. Jessica, Adrian, and Madee each presented posters on Sunday, during the opening mixer, and in Monday’s AES poster session. Arrion presented her poster on Wednesday, in the environmental analysis section. And Chris gave a talk on CE separations in one of the Tuesday AES oral sessions.
All in all it was a great time, and capped off by the SciX Wednesday night Gala “A Night at the Oscars”, where everyone was dressed to kill, and Madee got the dancing started in style.
Chris also coordinated a Sunday morning SciX bicycle ride, which is something far too few conferences have on their schedules.
Congratulations to Jessica on starting an internship at JPL/NASA this week!
Jessica will be working with Dr. Peter Willis to help optimize, and improve CE techniques for the detection of chemical signatures of life. The overarching goal of this work is develop, and hopefully deploy, microfluidic devices on probes to other planets or moons, in order to search for the chemical signatures of past or present life on those worlds.
We will certainly miss having Jessica in the lab for the next 10+ weeks, but it’s a great opportunity for her, and she will bring back some new techniques and knowledge to share with our lab.
