Current fundamental researches in the field of potentiometry demonstrate perspectives using polymeric nanostructured materials as ion-to-electron transducers Solid-Contact Potentiometric Sensors (SCSs). This paper reports preparation and comparative study plasticized Poly(Vinyl Chloride) (PVC) membranes modified with fullerene C60, single-walled carbon nanotubes SWCNTs, multiwalled nanotubes, g...

presently there are a number of fine and sensitive methods for determining chemical or biochemical substance among which bio electrodes represent the most recent development. bioelectrodes consist of biologically active materials (e.g enzyme, antibody, whole cell or cell fragments) held in close proximity to a suitable electrochemical transducer that sense specific electroactive enzyme substrat...

The mechanism by which dipicolylamine (DPA) chelate-appended fluorophores respond to zinc was investigated by the synthesis and study of five new analogs of the 2′,7′-dichlorofluorescein-based Zn2+ sensor Zinpyr-1 (ZP1). With the use of absorption and emission spectroscopy in combination with potentiometric titrations, a detailed molecular picture has emerged of the Zn2+ and H+ binding properti...

In this article, organic and polymeric materials, printing technology, sensing principles are investigated toward a reliable printed wearable pH sensor realized on textiles. A literature study experimental work of three different material-based sensors their corresponding measurement methods systematically made. Initially, the sensors, conductometric PEDOT:PSS sensor, voltametric carbon-alizari...
