    • The present invention relates to a container for an analyte-sensitive gel. When analyte contacts such a gel it causes a gel-sol transition resulting in decreased viscosity of the gel. Such gels can be used for controlling the rate of release of an agent from a reservoir in response to the concentration of an analyte. The container is configured to allow analyte to pass into the container and contact the gel and to allow agent to diffuse out of the container. Such a container may be implantable in the body of a subject and therefore it is preferred if the container is constructed from materials that can be tolerated by the body for a period of time. Advantageously, the container limits the swelling and dilution of gel contained within the container caused by the influx of water into the gel by osmosis. The container therefore maintains the gel in a desired conformation and ensures a predictable release profile of the agent.
    • 本发明涉及用于分析物敏感凝胶的容器。 当分析物接触这种凝胶时,它会引起凝胶 - 溶胶转变,导致凝胶的粘度降低。 响应于分析物的浓度,这种凝胶可以用于控制试剂从储存器释放的速率。 容器被构造成允许分析物进入容器并接触凝胶并允许药剂扩散出容器。 这样的容器可以植入到受试者的身体中,因此如果容器由身体可耐受一段时间的材料构造,则是优选的。 有利的是,容器限制容器内容纳的凝胶的膨胀和稀释,这是由于通过渗透将水注入凝胶而引起的。 因此容器将凝胶保持在期望的构型并确保试剂的可预测的释放曲线。
