Abstract: The present invention relates to a fuel cell including a metal anode as fuel and a biocompatible membrane.

Abstract: A light sensor and method of detecting light using the light sensor are provided. The light sensor includes a container having an anode compartment and a cathode compartment. The anode compartment has an anode and the cathode compartment has a cathode. The container also includes a transparent portion that allows light into the anode compartment. A membrane separates the anode compartment and the cathode compartment. The membrane is able to allow protons to pass from the anode compartment to the cathode compartment. The anode compartment includes a photon-converting compound (“PCC”) for generating electrons by reaction with light. Also included are an imaging device and a method of using the imaging device.

Abstract: The present invention relates to analyte sensors including a first compartment adapted for introduction of a sample potentially containing the targeted analyte, and a second compartment separated from the first compartment by a barrier, wherein the analyte interacts with a component in the first compartment, or a polypeptide associated with the barrier, resulting in the transport of a species across the barrier, the transported species or a derivative thereof being detected by a detector, thereby indicating the presence of the analyte.
