Influence of inflammatory cells and serum on the performance of implantable glucose sensors

The objective of this investigation was to evaluate the influence of polymorphonuclear granulocytes on the performance of uncoated and cellulose acetate/Nafion® coated amperometric glucose sensors in vitro. The response of these sensors was also investigated in serum. Uncoated and coated sensors showed lower sensitivities to glucose, with a...

Poly(3,4-ethylenedioxythiophene)-based glucose biosensors

Amperometric biosensors for the recognition of glucose oxidase (GOx) based on poly(3,4-ethylenedioxythiophene) (PEDOT) were fabricated for the first time. The resulting biosensor has potential applications for long-term glucose measurements.

Third-generation glucose biosensor incorporated in a conducting printing ink

A biosensor based on a conducting screen-printing ink for the direct amperometric measurement of glucose is described. Carbon electrode prints, containing the work, reference and auxiliary electrodes, are used as the substrate for the sensor. The active parts of the carbon ink are the redox enzyme glucose oxidase and the conducting polymer poly...
