    Abstract: A device (1) for use in the detection of binding affinities comprises a planar waveguide (2) arranged on a substrate (22). The waveguide (2) has an outer surface (21) and a plurality of incoupling lines (31) for coupling a beam of coherent light into the waveguide (2) such that a parallel beam of coherent light (62) propagates along the waveguide (2). The incoupling lines (31) are curved and have an increasing distance between adjacent incoupling lines (31). A divergent beam of coherent light (61) of a predetermined wavelength is coupled into the waveguide (2) such that it propagates along the waveguide (2). A plurality of binding sites (51) is attached to the outer surface (21) along at least one further plurality of diffraction lines arranged in an outcoupling section of the waveguide (2). These diffraction lines comprise a plurality of curved outcoupling lines (41) having a decreasing distance between adjacent outcoupling lines. They decouple a diffracted portion of coherent light from the planar waveguide (2), and the decoupled portion of coherent light (63) converges into a predetermined second focal location (631).

    Abstract: The present invention generally relates to antigen binding receptors capable of specific binding to mutated Fc domains with reduced Fc receptor binding and T cells expressing these antigen binding receptors. More precisely, the present invention relates to T cells, transfected/transduced with an antigen binding receptor which is recruited by specifically binding to/interacting with the mutated Fc domain of therapeutic antibodies. Furthermore, the invention relates to a kit comprising the T cells of the invention and/or nucleic acid molecules, vectors expressing antigen binding receptors of the present invention and (a) tumor targeting antibody/antibodies comprising a mutated Fc domain. The invention also provides the production and use of T cells in a method for the treatment of particular diseases in conjunction with tumor-specific antibodies as well as pharmaceutical compositions/medicaments comprising T cells and/or therapeutic antibodies, wherein T cells are to be administered in combination with therapeutic-tumor targeting antibody/antibodies comprising a mutated Fc domain with reduced Fc receptor binding.
