A urea biosensor has been prepared by covalent binding of urease directly to the surface of
an ammonium-sensitive field effect transistor (FET). The NH4+-sensitive membrane is based …

This review discusses current development in biosensors for the detection of biological
warfare agents (BWAs). BWAs include bacteria, virus and toxins that are added deliberately …

ABSTRACT A new amperometric urea biosensor based on gold nanoparticle embedded
poly (propylene-co-imidazole) was developed for the determination of urea. The urease …

Detection and quantification of glucose and urea are fundamental in medical analysis, real‐
time monitoring, and point of care analysis. However, such analyses generally require …

A new silver solid-state ion-selective electrode has been prepared by directly coating the
surface of a glassy carbon electrode with tetrahydrofuran solution containing PVC, 25, 27 …

A novel, highly sensitive and stable conductometric biosensor for creatinine determination is
developed. The biosensor is based on solid-state contact ammonium-sensitive sensor …

Polyvinyl chloride (PVC) is one of the most widely used polymers in medicine but has very
poor biocompatibility when in contact with tissue or blood. To increase biocompatibility …

A commercially available trypsin–chymotrypsin mixture was covalently immobilized onto
modified polyvinyl chloride (PVC) microspheres, which were activated by the subsequent …

The urease enzyme of Helicobacter pylori was isolated from biopsy sample obtained from
antrum big curvature cell extracts. A new urea biosensor was prepared by immobilizing …

A modular technique was used to synthesize an ammonium-selective ionophore based on a
cyclic depsipeptide structure. The ionophore was incorporated into a planar ion-selective …
