Abstract
A method of forming a 3-phenylimino-3H-phenothiazine or a 3-phenylimino-3H-phenoxazine mediator includes providing a first reactant including phenothiazine or phenoxazine, providing a first solvent, providing a second reactant and providing a second solvent. The first reactant, first solvent, second reactant and second solvent are combined to form a reactants solution. Sodium persulfate is added to the reactants solution to couple the first and second reactants resulting in a reaction solution including the 3-phenylimino-3H-phenothiazine or the 3-phenylimino-3H-phenoxazine mediator.

26. A method of forming a 3-phenylimino-3H-phenoxazine mediator, the method comprising the acts of:
-
providing a first reactant including phenoxazine; providing a first solvent in which the phenoxazine has a desired solubility therein; providing a second reactant to assist in forming the 3-phenylimino-3H-phenoxazine mediator; providing a second solvent in which the second reactant has a desired solubility therein; combining the first reactant, first solvent, second reactant and second solvent to form a reactants solution; adding sodium persulfate to the reactants solution to couple the first and second reactants resulting in a reaction solution including the 3-phenylimino-3H-phenoxazine mediator; and after adding the sodium persulfate, further processing to the reaction solution including the 3-phenylimino-3H-phenoxazine mediator so as to isolate the 3-phenylimino-3H-phenoxazine mediator. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A method of forming and stabilizing a 3-phenylimino-3H-phenoxazine mediator, the method comprising the acts of:
-
providing a first reactant including phenoxazine; providing a first solvent in which the phenoxazine has a desired solubility therein; providing a second reactant to assist in forming the 3-phenylimino-3H-phenoxazine mediator; providing a second solvent in which the second reactant has a desired solubility therein; combining the first reactant, first solvent, second reactant and second solvent to form a reactants solution; adding a coupling agent to the reactants solution to couple the first and second reactants resulting in a reaction solution including the 3-phenylimino-3H-phenoxazine mediator; and after adding the coupling agent, further processing to the reaction solution including the 3-phenylimino-3H-phenoxazine mediator so as to isolate the 3-phenylimino-3H-phenoxazine mediator; and stabilizing the 3-phenylimino-3H-phenoxazine mediator to a pH of from about 5 to about 8. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43)
