Abstract:
1. A glucose sensor for implantation within subcutaneous tissue of an animal body, the glucose sensor comprising: a first chamber containing (i) first magnetic particles and (ii) a first hydrocolloid solution having a viscosity which is dependent on and/or a function of the concentration of glucose in the first chamber, wherein the first magnetic particles are dispersed in the first hydrocolloid solution and wherein, when the first chamber is implanted in subcutaneous tissue of the animal body, glucose in the animal body may enter and exit the first chamber; and a reference chamber containing (i) second magnetic particles and (ii) a reference solution wherein the second magnetic particles are dispersed in the reference solution, and wherein, when the reference chamber is implanted in subcutaneous tissue of the animal body, glucose in the animal body does not enter the reference chamber.
