A dual-transducer flow-injection biosensor detection system for monitoring organophosphorus (OP) neurotoxins is described. Such simultaneous use of different physical transducers in connection to the same (organophosphorous hydrolase (OPH)) enzyme enhances the information content and provides discrimination between various subclasses of OP compounds. While the potentiometric biosensor responds ...
Peptide nucleic acid (PNA) has outstanding affinity over DNA for complementary nucleic acid sequences by forming a PNA-DNA heterodimer upon hybridization via Watson-Crick base-pairing. To verify whether PNA probes on an electrode surface enhance sensitivity for potentiometric DNA detection or not, we conducted a comparative study on the hybridization of PNA and DNA probes on the surface of a 10...
From the analysis of the potentiometric titration data of polyelectrolytes, we can obtain the electrostatic free energy of the macromolecules. Therefore, potentiometric titration is a useful experimental procedure to study the conformation and conformational change of macromolecules. A few examples of the application of potentiometric titration to the studies on polypeptides, protein and DNA ar...
Here, a simple, quick, Low cost and sensitive Potentiometric method is described for tramadol hydrochloride measurement using .PVC membrane electrode based on neutral ligand (E)-N'-(1-(2-hydroxyphenyl)ethylidene)benzohydrazid. Besides, effect of various parameters like ionic additives, membrane solvent and pH on the Potentiometric response of the electrode are investigated. The best electrode p...
