Description: 
Cytokine proteins are known as biomarker molecules, characteristic of a disease or specific body condition. Monitoring of the cytokine pattern in body fluids contributes to the diagnosis of rheumatic diseases associated with rheumatoid factor. Here, the proinflammatory cytokine Tumor Necrosis Factor alpha (TNF-α) was chosen as the first target of interest. We report on the development of a fast sandwich immunosorbent assay: anti-TNF-α antibody (Ab) immobilization on a pre-activated 3D micro-structured glass slide, coupled with direct fluorescence readout method. Two differently functionalized glass - Ab-immobilization substrates - were compared: O2 PLASMA/APTES activated glass - having a two-dimensional structure-, and the polystyrene (PS) beads coated glass, -having a 3D structure-. The 3D structured substrate was aimed to increase antibody anchorage sites. Then, the optimization of buffer …
