How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
Full-text available
In this article a rotating droplet system is used for simultaneous detection of dopamine and serotonin. Carbon nanoparticles functionalized with sulfonic groups on the electrode surface enables potential discrimination between the neurotransmitters and the most common interferences, whereas the efficient and low-volume hydrodynamic system helps to...

We present an electrochemical, microfluidic system with a working electrode based on an ordered 3D array of pencil leads. The electrode array was integrated into a plexiglass/PDMS channel. We tested the setup using a simple redox probe and compared the results with computer simulations. As a proof of concept application of the device we showed that...

Electronic tongue systems are traditionally used to analyse: food products, water samples and taste masking technologies for pharmaceuticals. In principle, their applications are almost limitless, as they are able to almost completely reduce the impact of interferents and can be applied to distinguish samples of extreme complexity as for example br...
Article
In this work, we explore generation-collection electrochemistry in a rotating droplet hydrodynamic system, where a 70 microliter droplet containing a redox active species (ferrocyanide) is sandwiched between an upper rotating rod and bottom nonmoving generator and collector planar electrodes. In such a system, we studied the effect of the counter e...
Article
We present a simplified and flexible implementation of the rotating droplet (RD) method as an alternative to rotating disc electrodes for electrochemical measurements in a small volume system. The rotating droplet system is based on the principle of a rotating disc electrode, but the method uses only a single droplet of the investigated solution to...
Article
As diabetes is considered one of the biggest health care challenges of the coming decades substantial effort is being made to develop novel glucose monitoring systems, this includes thousands of articles which are being published every year. To the question in the title, we answer an unequivocal "yes", but maybe not necessarily in the areas where m...
Article
Full-text available
The electrocatalytic oxidation of neurotransmitters on the electrodes modified with oppositely charged carbon nanoparticles has been investigated. These nanoparticles were deposited at the electrode from the aqueous suspensions via a layer-by-layer method. The electrocatalytic response was evaluated by cyclic voltammetry, differential pulse voltamm...
