Research ArticleOpen accessPhrase in the titleElectroanalytical Determination of Doripenem using a Screen-Printed ElectrodeNora H. Al-ShaalanProblem statement: The performance characteristics of Sensitive Screen-Printed (SPE) and Carbon Paste (CPE) electrodes were investigated for the Determination of Doripenem (DP) in pure, pharmaceutical preparations and biological fluids. Approach: The proposed electrodes is characterized in terms of plasticizer type, response time, pH and temperature. Results: The two electrodes showed nearly Nernstian behaviours over the concentration range of 2×10−4-5×10−2 mol/l … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 1 · 21 Feb 2012 · 7,664 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleConstruction of a Glucose Biosensor by Immobilizing Glucose Oxidase within a Poly(o-phenylenediamine) Covered Screen-printed ElectrodeMiao Yuqing, Chen Jianrong, Wu XiaohuaThe glucose biosensors were prepared by the electropolymerization of the non-conductive polymer, Poly(o-phenylenediamine), onto a planar screen-printed electrode. A fabrication procedure was performed to decrease the waste of expensive enzyme. The amperometric glucose response was measured by the potensiostating of the prepared glucose biosensors at a potential of 0.3 V with ferrocene as mediator. Results show that the obtained biosensors … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 6,843 accessesView PDF Cite
