Improvement in the long-term stability of an amperimetric glucose sensor system by introducing a cellulose membrane of bacterial origin

A classical amperometric glucose sensor was covered with a bacterial cellulose membrane, and its surface and long-term stability were tested in vitro and in vivo. The results show that the use of a modified bacterial cellulose membrane to cover the classical amperiometric glucose sensor significantly improves the sensor's long-term stability both in vitro and in vivo.
