Abstract
A microsensor for the determination of glucose and other analytes in liquids, based on affinity viscosimetry. The sensor based on affinity viscosimetry with stable working properties can be sufficiently minaturized for implantation in the organism. The sensor has a completely closed liquid conducting system having a dialysis chamber of a dialysis hollow fiber filled with the aqueous polymer system, and a measuring system for electrical signal transduction working in such a way that the sensitive polymer solution and eventually other liquids which are not miscible but hydraulically coupled with the polymer solution, are able to move on a closed path. The measuring system contains a micromotor to induce the liquid movement and a signal transducer sensitive to either pressure, volume or streaming to form signals related unequivocally to viscosity.
