Transfer of highly hydrophilic ions between immiscible liquids at the three-phase junction using a squaramide-based ion pair receptor

In a recently published paper in Electrochimica Acta, Julia presents the results of her investigations of two new squaramide-based ion-pair receptors for ion transfer at a three-phase electrode. The compounds, which were synthesised by colleagues from Warsaw University had previously been used to transfer hydrophilic ions across a liquid-liquid interface, […]

Cu(II) binding to an antimicrobial shrimp peptide – a small step for structural chemistry, a big leap for medicinal applications

Conference trips can bring new collaborations, especially when you are open to discussions and meeting new people (read scientists). At the 2nd French-Polish Chemistry Congress held in 2023, Martin heard Magdalena Rowińska-Żyrek give a talk on the antimicrobial properties of Zn- and Cu-complexes with peptides from shrimp and this meeting […]

Optical Interfacing of Plasmonic Waveguides with Colloidal Quantum Dots

The year started with the publication of an article in J. Phys. Chem. C on propagating plasmons in silver nanowires. This work in yet another in the series of articles on silver nanostructures and plasmons run by our neighbours in the Surface Nanoengineering group and the Maćkowski group in Toruń. In this work, it was […]

Spectroelectrochemical studies of TDMQ20: A potential drug against Alzheimer’s disease

Collaboration is extremely important to us. Gaining new knowledge, both practical and theoretical, is also extremely important. For this reason, Magda went on a 6-month internship to Professor Alvaro Colina’s group in Burgos, Spain. The cooperation turned out to be very successful because shortly after her return our first article […]

NFC Smartphone-Based Electrochemical Microfluidic Device Integrated with Nanobody Recognition for C-Reactive Protein

In a follow-up from our previous paper on point-of-care sensors for C-reactive protein (CRP), an article based on the same principle was just published in ACS Sensors. There are two main differences: instead of a peptide as recognition element, we used a nanobody, and we used a new smartphone-based potentionstat. […]

Redox behaviour of Cu-Aβ(4-16) complexes related to Alzheimer’s Disease

The next paper in Magda’s series of articles on the redox behaviour of β-amyloids relevant for Alzheimer’s disease has just hit the press. Here we have been looking at how the presence of a redox-active amino acid, tyrosine (Tyr), affects the oxidation of a Cu(II) attached to the amino terminus […]
