Our chemical fingerprinting method to discriminate polycyclic aromatic hydrocarbons (PAHs), persistent pollutants with significant health and environmental consequences, has been accepted for publication in Chemical Science. The method was developed by Nick White and Michael Ihde in our group, using polymers developed by Joshua Tropp and Dr. Jason Azoulay at the School of Polymers at the University of Southern Mississippi. Our method, based on detecting how PAHs affect the fluorescence of fluorene-based conjugated polymers through the inner-filter effect (IFE), was able to discriminate between 16 PAH compounds identified as priority pollutants by the US Environmental Protection Agency (EPA).
Yifei, and Xiyuan, graduate students in the group, are organizing a student-led symposium at the upcoming Fall ACS meeting in San Diego (August 2019). They are lining up some really interesting speakers, so plan to stop by if you are at the conference!
Carbohydrate sensing in water is very challenging. In collaboration with the Kharlampieva group at UAB, Xiaoli Liang in our group was recently able to improve the solubility of boronic acds in water and the affinity of their interaction with carbohydrates, by connecting phenylboronic acid moieties to a hydrophilic poly(methacrylic acid) polymer to generate a water-soluble copolymer that can be used as a supramolecular receptor. Coupled with an indicator displacement assay, this polymer was able to differentiate both monosaccharides and disaccharides in neutral aqueous solution.
This work was recently published in ACS Applied Polymer Materials where it was featured on the cover (left).
Gabrielle Covey, an experienced undergraduate researcher in our group, presented a talk at the ACS Southeastern Undergraduate Research Conference (SURC 2019) held this year at the University of Tennessee - Martin. She spoke on her research on metal complexation by modified rhodamine dyes carried out in collaboration with the Wallace Group at the University of Southern Mississippi.
Just like past years, many of us participated in the presentations at the 2018 Southeastern Regional Meeting of the American Chemical Society (SERMACS 2018, Augusta, GA).
Michael, Xiaoli, and Yifei, three graduate students in the group, organized a student-led symposium at the Fall ACS meeting in Boston (August 2018). The speaker lineup was stellar!
Addison Iszler, an undergraduate researcher in our group working on the characterization of "knockout" analogues of PAMAM dendrimers who was recently recognized with the Randall research award, presented a poster at the Undergraduate Research and Creative Activities conference today on the UA campus. Good job Addie!
Our paper on the thermodynamic origin of the selectivity (or lack thereof) of a transition metal based receptor to a series of anions, stemming from work done by Michele Invernici, a visiting graduate student from Italy who spent six months in our group, has been accepted for publication in Chemistry - a European Journal! Here is a link: http://dx.doi.org/10.1002/chem.201800067
Dr. Bonizzoni was invited to present at the 2017 CASE (Catalysis and Sensing for our Environment) conference, organized in Shanghai, China by Prof. Yujun Yang (ECUST).
Xiaoli presented a poster today on the detection of sugars using boronated polymers at the 5th WiSE (Women in STEM Experience) Symposium organized by the University of Alabama. Her poster was selected to win the First Prize Poster Award! Congratulations Xiaoli!
