Investigation of liquids with microcavity in-line Mach-Zehnder interferometers – impact of the microcavity shape on the sensing performance

In this invited paper we studied the difference that the shape of the microcavity has in in-line Mach-Zehnder interferometers has on their sensitivity. This work is related to previous publications in collaboration between our group and Prof. Śmietana at Warsaw University of Technology., In the previous publications we used a […]

Microfluidic devices for photo-and spectroelectrochemical applications

Together with our partners in the UPTURN project we wrote a short review article about the use of combining electrochemical and optical methods in microfluidic systems. The goal of UPTURN is to create a suitable microfluidic platform for multiparametric measurements. This was a good opportunity to summarise what is available […]

Very small changes in the peptide sequence alter the redox properties of Aβ(11-16)-Cu(II) and pAβ(11-16)-Cu(II) β-amyloid complexes

Sometimes publishing doesn’t go according to plan…. Our newly published article in J. Electroanal. Chem. was supposed to have been published before the follow-up in ChemElectroChem. We thought it made sense to first study the shorter amyloid and then follow with a study of the longer one. Some review delays […]

The Influence of Coordination Mode on the Redox Properties of Copper Complexes with Aβ(3-16) and its Pyroglutamate Counterpart pAβ(3-16)

Over the last year, Magda has been working with bachelor student Natalia to investigate the redox behaviour of different β-amyloids. In her recently published paper she demonstrates a significant difference in the redox behaviour of copper complexes with peptides associated with Alzheimer’s disease (AD). AD is a neurodegenerative disorder and […]

A microfluidic system for analysis of electrochemical processing using a highly sensitive optical fiber microcavity

After months of work on the article, Martin and Andrzej finally got their second paper about electrochemical and optical studies using an optical fiber accepted. The article “A microfluidic system for analysis of electrochemical processing using a highly sensitive optical fiber microcavity” will be published in the journal “Optics and […]

Electrochemistry in an optical fiber microcavity – optical monitoring of electrochemical processes in picoliter volumes

We just published an article combining electrochemistry and interferometry in a microcavity. This work was done in collaboration with colleagues from Warsaw University of Technology and the National Institute of Telecommunications, who are responsible for the optics part of the work. The experiment is based on a microcavity in-line Mach-Zehnder […]

The spectroelectrochemical behaviour of 1,4‐dimethoxypillar[5]arene (P5A) and its monomer in different organic solvents

Pillararenes were introduced as a novel class of macrocyclig host molecules in 2008 when 1,4-dimethoxypillar[5]arene (P5A) was synthesised. The pillararenes are similar in structure to the better known cyclodextrins or calixarenes and they can also form host-guest complexes with smallish molecules that can fit into their cavities. In a recent […]

Patterned silver island paths as high-contrast optical sensing platforms

Another paper has come out in the silver nanostructure series with our neighbours in the Surface Nanoengineering group and the Maćkowski group in Toruń. This time the focus is on silver island paths – basically SIFs deposited along lines on a substrate. The idea here, as the title indicates, is to use the contrast between fluorescence enhancement on […]
