(A) The performance of the different SAMs (DTSP SAMs and 3-Mercaptopropionic acid (MPA) SAMs); (B) The absorption capacity of SPIMs with or without SAMs; (C) Comparison of the SPIMs (200 µm width of electrode fingers) and interdigitated microelectrodes (IDMs, 25 µm width of electrode fingers); and (D) The optimization of the antibody concentration. All the experiments were repeated more than three times.
