Enzyme Biosensor for Determination of Organophosphates
A potentiometric enzyme biosensor for the direct measurement of organophosphate pesticides was developed. The basic element of this enzyme biosensor was a pH electrode modified with an immobilized organophosphorus hydrolase layer formed by cross-linking OPH with bovine serum albumin and glutaraldehyde. Organophosphorus hydrolase catalyzes the hydrolysis of organophosporus pesticides to release ...
متن کاملSol–gel-derived thick-film conductometric biosensor for urea determination in serum
A conductometric urea biosensor based on sol–gel-immobilized urease on a screen-printed inter-digitated array (IDA) electrode has been developed. The screen-printed thick-film IDA electrode has proven to be an excellent conductometric transducer in which the admittance signal was dominated by the conductance signal and the resulting dynamic range was wide enough to be employed for the construct...
متن کاملDevelopment of an electrochemical maltose biosensor
In this work, electrochemical maltose biosensors based on mutants of the maltose binding protein (MBP) are developed. A ruthenium complex (Ru), which is covalently attached to MBP, serves as an electrochemical reporter of MBP conformational changes. Biosensors were made through direct attachment of Ru complex modified MBP to gold electrode surfaces. The responses of some individual mutants were...
متن کاملA Conductometric Indium Oxide Semiconducting Nanoparticle Enzymatic Biosensor Array
We report a conductometric nanoparticle biosensor array to address the significant variation of electrical property in nanomaterial biosensors due to the random network nature of nanoparticle thin-film. Indium oxide and silica nanoparticles (SNP) are assembled selectively on the multi-site channel area of the resistors using layer-by-layer self-assembly. To demonstrate enzymatic biosensing capa...
متن کاملConductometric determination of propranolol hydrochloride in pharmaceuticals
______________________________________________________________________________ In this paper the conductometric titration of propranolol hydrochloride in pharmaceutical formulations using silver nitrate as titrant is proposed. The method was based on the formation of an insoluble salt (AgCl(s)) between the chloride of propranolol hydrochloride molecule and Ag(I) ions of the titrant AgNO3. The e...
