Arkady A. Karyakin,Elena A. Puganova,I. A. Budashov,Ilya N. Kurochkin,Elena E. Karyakina,V.A. Levchenko,Vladimir N. Matveyenko,S.D. Varfolomeyev +7 more
TL;DR: The resulting Prussian Blue based nanoelectrode arrays in flow injection analysis mode demonstrate a sub-part-per-billion detection limit and a linear calibration range extending over 6 orders of magnitude of H(2)O( 2) concentrations, which are the most advantageous analytical performances in hydrogen peroxide electroanalysis.
Journal ArticleDOI
The development of a new biosensor based on recombinant E. coli for the direct detection of organophosphorus neurotoxins.
TL;DR: A new biosensor for the direct detection of organophosphorus (OP) neurotoxins has been developed utilizing cryoimmobilized, recombinant E. coli cells capable of hydrolyzing a wide spectrum of OP pesticides and chemical warfare agents.
Journal ArticleDOI
The electrochemical polymerization of methylene blue and bioelectrochemical activity of the resulting film
Arkady A. Karyakin,A.K. Strakhova,Elena E. Karyakina,S.D. Varfolomeyev,Anatoly K. Yatsimirsky +4 more
TL;DR: In this paper, the electrochemical polymerization of methylene blue in aqueous solutions and the properties of the resulting films were investigated, and the films possessed monomer-type redox activity, and a new redox couple was observed.
Journal ArticleDOI
Denaturation and partial renaturation of a tightly tetramerized DsRed protein under mildly acidic conditions.
TL;DR: It is found that with time DsRed fluorescence decreases under mildly acidic conditions (pH 4.0–4.8) in a pH‐dependent manner, and this fluorescence inactivation could be partially recovered by subsequent re‐alkalization.
