Several methodologies have been used in clinical chemistry for real-time assessment of NADPH oxidase primary product superoxide anion which dismutases to hydrogen peroxide. Among these methodologies, isoluminol chemiluminescence (CL) is considered to be one of the more sensitive and reliable techniques for the assessment of NADPH oxidase activity in(More)
N-(3-Aminopropyl)pyrrole was covalently coupled with alginate in an aqueous-phase reaction by means of carbodiimide-mediated activation chemistry to provide a pyrrole-alginate conjugate for subsequent use in biosensor applications. The pyrrole-alginate conjugate was quantified by UV spectroscopy at 230 nm, by an HPSEC-MALLS analytical method, as well as by(More)
A conductive surface was created for the development of a biosensing platform via chemical polymerization of pyrrole onto the surface of poly(methyl methacrylate) (PMMA) fibers, with a subsequent electrogeneration of a photoactive linker pyrrole-benzophenone (PyBz) monomer on the fiber surface. Irradiation of the benzophenone groups embedded in the(More)
Herein the development of an alternative optic-conductive fiber configuration applied for the construction of biosensing platforms. This new approach is based on applying the chemical polymerization of pyrrole onto the surface of polymethyl metacrylate (PMMA) fibers to create a polymer--a conductive surface, onto which an additional photoactive(More)
With the aim of detecting rapidly the presence of Escherichia coli (E. coli), a disposable amperometric immunosensor was developed based on a double layered configuration at the transducer surface, consisting first of a polypyrrole-NH(2)-anti-E. coli antibody (PAE) inner layer followed by an alginate-polypyrrole (Alg-Ppy) outer packing layer. In the(More)
