In this work we present typical problems and solutions concerning the development of prototyping electrochemical measurement cells for biosensoric applications. The influences of unwanted effects are discussed such as 1) the variation of gold thin film working electrode surface areas due to the technological inaccuracy of the laser ablation electrode patterning; 2) the variation of the working electrode...
Gold nanoparticles (NPs) of 10-50 nm in diameter were synthesized on nitrogen incorporated diamond-like carbon (DLC:N) thin film electrode by electrodeposition. The deposition process of Au was investigated by cyclic voltammetry and chronoamperometry. The morphology of Au NPs was characterized by scanned electron microscopy. The potentiostatic current-time transients showed a progressive nucleation...
To identify dairy cows suffering from subclinical mastitis, we used the fact that the number of neutrophils increases in raw milk. The neutrophils, a type of white blood cells, produce superoxide (O2). Therefore, the amount of O2 produced in raw milk can be used as an indicator for mastitis. To this end, we fabricated a device consisting of thin-film threee-lectrode systems. A self-assembled monolayer...
