Abstract
The present invention forms a detection layer in an embedded biosensor probe by using a phenazine derivative as a redox mediator in which a phenazine group is covalently bonded to a high molecular weight polymer having a carboxyl group or an amino group, such as polyamino acid, polyimine, or polyallylamine; and the distance between the phenazine group and the high molecular weight polymer main chain is increased by using a polyethylene glycol chain.
Claims4
A sensor for detecting or quantifying a specimen contained in a sample, comprising at least a phenazine derivative represented by general formula (1):
- wherein X− represents an anionic species, and R represents an organic group having an amino group or a carboxyl group at an end;
- and a specimen-responsive enzyme.
