Claim 0:
1. A system for continuous in vivo detection of an analyte, the system comprising:
a continuous analyte sensor comprising a working electrode configured for implantation in a host, wherein the working electrode comprises an electroactive surface, the continuous analyte sensor further comprising a membrane located over the working electrode, wherein the membrane comprises an enzyme domain and a particle-containing domain, wherein the particle-containing domain comprises a conductive component dispersed in a non-conductive component, wherein the conductive component comprises a plurality of conductive particles comprising 1 wt. % to 90 wt. % of the particle-containing domain, wherein the particle-containing domain is located more distal to the electroactive surface than the enzyme domain, and wherein the particle-containing domain is configured to electrochemically react with at least one interfering species; and
sensor electronics configured to generate a signal associated with the analyte in the host.
