Stable biosensor production, comprises coating a redox mediator layer with an adhesive hydrogel gelled at low temperature

摘要

Producing a biosensor, comprising depositing a redox mediator on the working electrode of a sensor and coating the redox mediator with an adhesive hydrogel by contacting the sensor with an aqueous solution of the hydrogel at 2 deg C or less, keeping the sensor at -5 to 0 deg C for 20-40 minutes, and gelling the solution at 4 deg C.
