Monitoring of total potassium in winemaking processes using a potentiometric analytical microsystem

New Insights on Potentiometric Immunosensor at Carbon Fiber Microelectrode for Alpha‐Fetoprotein in Hepatocellular Carcinoma

“…Calvo‐Lopez et al . constructed an analytical microsystem by using carbon ink‐based electrode for potentiometric detection of potassium in winemaking processes [6]. In contrast, ongoing interest has been observed for carbon fiber‐based microelectrodes [7].…”

“…Draz et al prepared a polyvinyl chloride (PVC)-based solid-state potentiometric sensor for assay of the biologically active biogenic amine (tyramine) [5]. Calvo-Lopez et al constructed an analytical microsystem by using carbon ink-based electrode for potentiometric detection of potassium in winemaking processes [6]. In contrast, ongoing interest has been observed for carbon fiber-based microelectrodes [7].…”

Serum/plasma potassium monitoring using potentiometric point-of-care microanalyzers with improved ion selective electrodes

“…For the reference electrode, Ag/AgCl paste was screen-printed using the DEK 248 screen-printer machine (DEK, Spain), being cured for min at 80 • C. For the integration of the conductive support for the potassium selective electrode, a carbon ink was used following a previously optimized procedure [22,23]. It involves refilling with ink the bas-relief machined on the COC layer (Fig.…”

“…Lifetime of polymeric membranes used in ISE is an important factor often overlooked but crucial, especially to implement in practice. In most cases, potentiometric devices for measuring potassium ion use Valinomycin as a recognition element and DOS as a plasticizer [22,24,[26][27][28][29]. This type of polymeric membranes have been extensively studied and show adequate analytical features for the intended applications, in particular for those that do not require intensive use of the electrodes.…”

The influence of agricultural practices in vineyards on the predisposition of wines to crystalline turbidities

“…Various technological equipment and auxiliary materials can be used to combat crystalline turbidities [3][4][5][6][7][8][9][10][11], however, most of the methods for stabilizing wines to crystalline turbidities are extremely expensive and / or energy-intensive, as a result of which many enterprises, especially small farms, simply can not afford to use them.…”
