GFAP Antibody Detection Using Interdigital Coplanar Waveguide Immunosensor

Glioma is the most common primary brain tumor with its early detection remaining a challenge. Autoantibodies against glial fibrillary acidic protein (GFAP) have shown the highest differential expression compared with the other glioma expressed autoantibodies. In this paper, an immunosensor to detect GFAP antibody levels is developed using an interdigital coplanar waveguide (ID-CPW). The ID-CPW is ...
