Beta-galactosidase Determination by an Electrochemical Biosensor Mediated with Ferrocene
(Informa Healthcare, 2011)
In this paper, a new viewpoint on the activity determination of beta-galactosidase is reported. Glucose oxidase was directly immobilized on a glassy carbon electrode and mediated by ferrocene. The biosensor's performance ...
Construction and Comparison of Trametes versicolor Laccase Biosensors Capable of Detecting Xenobiotics
(Informa Healthcare, 2010)
Amperometric biosensors using laccase from Trametes versicolor as a bioelement were developed for 2,4-dichloro phenoxy acetic acid (2,4-D). Laccase enzyme was immobilized by gelatin and glutaraldehyde onto a Clark oxygen ...
A New Voltammetric Method for the Determination of Lercanidipine in Biological Samples
(Slovensko Kemijsko Drustvo, 2011)
Electrochemical behavior and adsorption-diffusion properties of lercanidipine (LCN) on a glassy carbon electrode (GCE) were investigated in a mixture of ethanol-Britton Robinson buffer (BR) using voltammetric methods. From ...
A new impedimetric biosensor utilizing VEGF receptor-1 (Flt-1): Early diagnosis of vascular endothelial growth factor in breast cancer
(Elsevier Advanced Technology, 2011)
A new impedimetric biosensor, based on the use of vascular endothelial growth factor receptor-1 (VEGF-R1), was developed for the determination of vascular endothelial growth factor (VEGF). VEGF-R1 was immobilized through ...
A Biosensor for the Determination of beta-galactosidase Activity: A Different Viewpoint on Biosensors
(Informa Healthcare, 2011)
beta-galactosidase splits lactose into glucose and galactose. Because of its biotechnological interest, we presented a biosensor system in order to monitor beta-galactosidase activity. Immobilization steps of the biosensor ...
9-(4-Nitrophenylsulfonyl)-9H-carbazole
(Wiley-Blackwell, 2011)
In the title molecule, C18H12N2O4S, the carbazole skeleton is nearly planar [maximum deviation = 0.037 (1) A] and is oriented at a dihedral angle of 73.73 (5)degrees with respect to the benzene ring. An intramolecular ...
Biodiesel production from waste frying oils and its quality control
(Pergamon-Elsevier Science Ltd, 2010)
The use of biodiesel as fuel from alternative sources has increased considerably over recent years, affording numerous environmental benefits. Biodiesel an alternative fuel for diesel engines is produced from renewable ...
5-(3,6-Dibromo-9H-carbazol-9-yl)pentanenitrile
(Wiley-Blackwell, 2011)
In the title compound, C17H14Br2N2, the carbazole skeleton is nearly planar [maximum deviation = 0.055 (2) angstrom]. In the crystal, aromatic pi-pi stacking is observed between parallel carbazole ring systems of adjacent ...
9-Benzyl-9H-carbazole
(Wiley-Blackwell, 2010)
The asymmetric unit of the title compound, C(19)H(15)N, contains two crystallographically independent molecules. In both molecules, the planar carbazole moieties [maximum deviations = 0.037 (4) and 0.042 (3) angstrom] are ...
A Biosensor Based on Zucchini (Cucurbita Pepo L.) Homogenate as a Biorecognition Layer for Ascorbic Acid Determination
(Informa Healthcare, 2010)
An amperometric biosensor based on zucchini (Cucurbita pepo) tissue homogenate is presented. The zucchini tissue homogenate was crosslinked with gelatine using glutaraldehyde and fixed on a pretreated teflon membrane. The ...
