Delighted to have another article on glyco-metal complexes published in 𝘖𝘳𝘨𝘢𝘯𝘪𝘤 & 𝘉𝘪𝘰𝘮𝘰𝘭𝘦𝘤𝘶𝘭𝘢𝘳 𝘊𝘩𝘦𝘮𝘪𝘴𝘵𝘳𝘺. This work was led by Karolina Wojtczak, PhD and involved contributions and support from lots of colleagues across disciplines including the teams of Trinidad Velasco-Torrijos, Anne Imberty, Gordon Cooke (TUD), Dr. Cristina Trujillo and Kevin Kavanagh who put lots of work into ideas, assays, measurements and calculations to support our hypotheses.

Please read the full article in the RSC journal Organic and Biomolecular Chemistry, where it will be part of the 2025 New Talent Special Issue: https://doi.org/10.1039/D5OB00970G

Buíochas le Taighde Éireann Research Ireland as ucht tacaíocht.

Karolina defends her PhD thesis

Very proud of my very first PhD student Karolina Wojtczak who successfully defended her thesis last Thursday. A lot of hard work has paid off and she has left the group lots of interesting starting points for future projects (in addition to a few more imminent publications). Her thesis was titled “Metal-based glycoconjugates as molecular sensors for lectins and anti-adhesives”.

Karol was an absolute pleasure to have in my lab and I wish her all the best with her bright future. I’m sure she will achieve great things. Congratulations!

A great celebration was had in Galway to mark the occasion.

Thanks to Research Ireland (formerly SFI) (18/SIRG/5501) for financial support and Paul Murphy for co-supervising her, particularly after I moved to UCD last year.

Karol has already started a position as a Development Chemist in Sterling Pharma Solutions.

ChemComm: Terbium-based lectin sensors

Congratulations to Karolina on her first article published in Chemical Communications. The article has been included in the HOT Articles 2023 Collection as well as a themed collection on Chemosensors and Molecular Logic (related to last year’s MSMLG Conference). The work was considered exciting by the editors and so was featured on the Front Cover of the journal issue.

We describe glycoconjugate terbium(III) complexes, which are able to detect carbohydrate-binding proteins in aqueous buffer solution. When the carbohydrate motif on the complex matches the target of the protein, an enhancement in lanthanide luminescence is observed. The bacterial lectin LecA (from P. aeruginosa) is one of the detected proteins.

This work was funded by Science Foundation Ireland (18/SIRG/5501), with support from a 4th year project student, and our collaborators in TU Dublin (Gordon Cooke) and University of Saarland (Alexander Titz, HZI/HIPS). The interdisciplinary work includes synthesis of new sensor molecules, biological assessment and examination of their lectin binding affinity. We believe this work could lead to the development of tools which could use detection of characteristic proteins from pathogens as a means for diagnosis, and hope to follow up on this in future publications.

Group meeting at UCD and lunch

For the first time since the group moved to UCD, we had an in-person meeting of members from Galway and UCD. Karolina was returning from a research stay in Grenoble (funded by the French embassy in Ireland) and updated us on some exciting results, which Thomas, Hannah and Wanyujin gave updates on their work. Afterwards we went out for lunch at UCD Village to talk about future plans.

Karolina wins prize for talk at ICI Colloquium

Karol delivered an oral presentation at the Irish Universities Chemistry Research Colloquium in UCD on 15 June 2022 entitled “Shining a Light on Bacteria : Lanthanide- based Glycoconjugate Molecular Sensors for Lectins”. The talk was very well received, with lots of discussion arising afterwards. The judges at the Colloquium, the highlight of the Institute of Chemistry of Ireland’s scientific calendar, awarded her a prize for her talk.

May Outreach Activities

In May Karolina participated in two outreach events, talking about science to both adults and children alike! Pint of Science was held on the 11th of May in Massimo’s Bar in Galway. The first Pint of Science Festival to be held in person in two years was a sold-out event and over 50 people of all different backgrounds enjoyed Karol’s talk about antimicrobial resistance and how we can fight it using sugars, over a pint. 

The second event was the annual START Competition, held in NUI Galway on the 20th of May. An event geared towards primary school children in 4th, 5th and 6th class to mark the anniversary of the first documented randomised clinical trial in 1747, and learn more about all the different disciplines of science that make clinical trials possible. Karol along with her colleagues volunteered as part of Kitchen Chemistry to chat to students from three different schools and show them fun and safe experiments they can easily do in their kitchen. After lunch she also put on a show demonstrating how to make “elephant toothpaste” and the freezing power of liquid nitrogen with help from Darragh, Lamis and Hanka.
