Inkjet printed graphene (IPG) has recently shown tremendous promise in reducing the cost and complexity of graphene circuit fabrication. In this work, we fabricate an ion selective electrode (ISE) with IPG for the first time. A thermal annealing process in a nitrogen ambient environment converts the IPG into a highly conductive electrode (sheet resistance changes from 52.8 ± 7.4 MΩ/☐ for unanne...

A new wire-coated silver ion-selective electrode with a wider concentration range (10(-7) M - 10(-1) M) was developed using 2-mercaptobenzothiazole (MBT) as a neutral ionophore. An optimum mixture of PVC, ionophore, dioctylphtalate (DOP) as a plasticizer and sodium tetraphenylborate (NaTPB) as an ion-pairing agent was used in preparing the coatings. The effect of various parameters, such as the...

Two novel potentiometric membrane sensors responsive to the ibuprofen drug have been developed. These incorporate poly(vinyl chloride) and polyurethane matrix membranes containing 5,10,15,20-tetraphenylporphrinato (TPP) indium(II) ionophore plasticized with dibutylsebacate. The sensors show a near-Nernstian response with anionic slopes of -53 and -55 mV decade(-1), over the concentration range ...

Yeast trans-Golgi network (TGN) membrane proteins maintain steady-state localization by constantly cycling to and from endosomes. In this study, we examined the trafficking itinerary and molecular requirements for delivery of a model TGN protein A(F-->A)-alkaline phosphatase (ALP) to the prevacuolar/endosomal compartment (PVC). A(F-->A)-ALP was found to reach the PVC via early endosomes (EEs) w...

The construction and electrochemical response characteristics of PVC membrane and coated wire sensors for the determination of Benzydamine hydrochloride (Benz) are described. PVC membrane sensors, include sensors 1, 2 and 3, and coatedwire sensors include sensors 4, 5 and 6. Sensors 1 and 4 based on benzydamine phosphotungstate (Benz-PTA) as ion-pair, sensors 2 and 5 based on benzydamine phosph...

We have established an efficient transient expression system with several vacuolar reporters to study the roles of endosomal sorting complex required for transport (ESCRT)-III subunits in regulating the formation of intraluminal vesicles of prevacuolar compartments (PVCs)/multivesicular bodies (MVBs) in plant cells. By measuring the distributions of reporters on/within the membrane of PVC/MVB o...

Abstract The capacity of a synthetic ( N 1 E , 3 )- - bis (quinolin-2-ylmethylene)benzene-1,3-diamine Schiff base ligand to operate as cation carrier in poly(vinylchloride) (PVC) membrane (electrode I) and screen-printed ion-selective electrode (SPE) II) was investigated. the fabricated electrodes displayed outstanding response properties for Al(III) ions. had linear potential with slope 17.95 ...

The design, fabrication and performance characteristics of Kapton-based planar mini and semimicro potentiometric sensors with an Ag/AgCI or a quinhydrone-based redox internal reference electrode are described. The ion-selective membranes cast from conventional and various modified PVC matrices and containing different pH-sensitive ionophores are ranked on the basis of their performances in host...

In the present work, the seedless, highly aligned and vertical ZnO nanorods in 3 dimensions (3D) were grown on the nickel foam substrate. The seedless grown ZnO nanorods were characterised by field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), and X-ray diffraction (XRD) techniques. The characterised seedless ZnO nanorods in 3D on nicke...

This work describes an FIA potentiometric procedure for the quantification of dipyrone in pharmaceutical products. For the detector, a tubular electrode comprising a polymeric membrane containing tetraoctylammonium as an electroactive material (5% w/w), dibutylphtalate as a mediator solvent (65% w/w) and PVC (30% w/w) directly applied above a graphite conductor support was used. This unit was i...
