Electroanalytical Properties of Non-modified and Polyaniline Modified Solid Contact Cefazolin Selective Sensors

Cefazolin is a cephalosporin antibiotic of the third generation. It is widely used in medical practice for the therapy of various infectious-somatic pathologies. The work was aimed at the creation of solid-contact potentiometric cefazolin-selective sensors. For the first time, polyaniline was used to stabilize the potentials of solid-contact sensors. As the membranes active components, the compound of tetradecylammonium (TDA) with the silver (I) – cefazolin complex were applied.

Solid-state Potentiometric Sensors for the Determination of Cefuroxime Axetil in Aqueous Media and Oral Fluid

Cefuroxime axetil is a cephalosporin antibiotic of the second generation, it is used in the sequential therapy of patient with sinusitis, community-acquired pneumonia, and other infectious somatic pathologies. For the determination of cephalosporin antibiotics in different objects, spectroscopic, chromatographic, electrochemical methods, immunoassay, etc. are used, which demand for expen- sive devices and organic solvents. Potentiometric sensors let one expressively detect cefalosporin antibiotics in small samples without previous sample preparation.
