Abstract: An electromagnetic sensor for use in a variety of applications requiring extremely high sensitivity, such as measuring power and characteristics of incident electromagnetic radiation includes a superconducting layer that carries an exchange field for providing a spin splitting effect of charge carriers in the superconducting layer, a metal electrode, and an insulating layer arranged between the superconducting layer and metal electrode to form a spin filter junction therebetween. The electromagnetic sensor provides an antenna including a wave collecting element, in contact with the superconducting layer to convey thereinto external electromagnetic waves that are generated by an external source.

Abstract: The present invention relates to a method for detecting Borrelia burgdorferi sensu lato infection or the presence of antibodies against Borrelia species in a body fluid from a suspected infected or vaccinated human or other mammal, to a diagnostic kit useful in said method and to an immunoassay method for diagnosing early and late Lyme borreliosis, especially for diagnosing erythema migrans. The methods according to the invention are characterized in that recombinant BBK32 proteins, optionally other immunogenic borrelial proteins, or their fragments are used as antigens.
