A novel fully spray coating-based method of the preparation of all-solid-state ion-selective electrodes of simplified construction is proposed. This method is an alternative for screen-printed electrodes used sometimes in potentiometric applications. The benefits of the herein-proposed approach include fully automatic sensor preparation and minimized use of chemicals allowing for the production...

a simple, precise, rapid and low-cost potentiometric method for diclofenac determination in pharmaceuticals is proposed. a new diclofenac-sensitive electrode was constructed by incorporating the diclofenac ion pair complex with butyl rhodamine b into graphite matrix. the electrode exhibited a linear response over the concentration range of 1 × 10-4 – 5 × 10-2 mol l-1, a detection limit of 3.9×1...

A light-addressable potentiometric (silicon) sensor was used in an immunofiltration procedure for the detection of pathogenic bacteria. Yersinia pestis was detected by filtering the cells onto nitrocellulose membranes and then filtering anti-Y. pestis mouse monoclonal antibody and anti-mouse immunoglobulin G-horseradish peroxidase conjugate. For Neisseria meningitidis detection, mouse monoclona...

al3+-potentiometric sensor, based on (2z) -methyl 2- ((z) (p-tolylimino)-3-ethyl -4-oxothiazolidin -5- ylidene) acetate (mteoy) as a neutral ionophore, was successfully developed for the detectionof al3+ in aqueous solutions. the electrode responds to al3+ ion with a sensitivity of 19.8 ± 0.1 mv/decade over the range 1.0 x 10-8- 1.0 x 10-1 mol lt' and in a ph range of 3.0-9.0. the electrodeshow...
