Continuous analyte measurement system with particle-containing domain for implantation
A recently granted patent (Publication Number: US11918354B2) discloses a system for continuous in vivo detection of an analyte, such as glucose, in a host. The system includes a continuous analyte sensor with a working electrode containing an electroactive surface and a membrane with an enzyme domain and a particle-containing domain. The particle-containing domain, comprising a conductive component dispersed in a non-conductive component, is designed to electrochemically react with interfering species. The sensor electronics generate a signal associated with the analyte in the host, providing real-time monitoring capabilities.
The system's design allows for efficient detection of the analyte by utilizing a combination of materials for the conductive component, including platinum, graphite, silver, and conductive polymers. The method involves implanting the sensor into the host's tissue, allowing the membrane to facilitate the diffusion of the analyte. By applying a potential to the particle-containing domain, the system can accurately detect the concentration of the analyte. Additionally, the method includes electrochemically reacting the particle-containing domain with interfering species, either by oxidizing or reducing them, to ensure precise and reliable measurements. Overall, this patented system offers a sophisticated and effective solution for continuous in vivo monitoring of analytes, with a particular focus on glucose detection.
