Preparation and Properties of a Glucose Biosensor Based on an Osmium-Complex Modified Polypyrrole.

Development of a d-amino acids electrochemical sensor based on immobilization of thermostable d-Proline dehydrogenase within agar gel membrane

“…Thus, enzyme-based amperometric biosensors are useful as an alternative method because they have many advantages of high selectivity for analytes and compact mobility of the analytical system. The enzyme-based amperometric biosensors have been applied to determination of many compounds in biological and food fields [18][19][20].…”

Characterization of a Glucose Sensor Prepared by Electropolymerization of Pyrroles Containing a Tris-bipyridine Osmium Complex

“…19 We have previously developed and studied Os-py in conjunction with the immobilization of enzymes for preparing glucose sensors. 20,21 In this research, we synthesized several Os-pys, which were [Os(bpy)2(py(4)bpy)] 2+/3+ , [Os(bpy)2(py(3)-bpy)] 2+/3+ , [Os(bpy)2(py-pyridine)-Cl] +/2+ and [Os(bpy)2(vinyl-bpy)] 2+/3+ , and characterized the prepared sensors. The [Os(bpy)2(py(4)-bpy)] 2+/3+ effectively acted as a mediator and immobilized materials for GOx A glucose sensor was developed by electrocopolymerization using pyrroles containing a tris-bipyridine (bpy) osmium complex (Os-py), pyrrole (py), pyrrole propanoic acid (PPA) and glucose oxidase (GOx) to improve the key performance characteristics, such as the sensitivity, selectivity, and long-term stability.…”
