Silicon-Based Technology for Ligand-Receptor Molecular Identification
Figure 4
Binding of A20 cells to the functionalized silicon wafer. Images from optical microscope (20x enlargement) of the biochip functionalized with antibody anti-IgG (6,8 μM) and then incubated with A20 cells before washes (a) and after washes (b). Optical image after washes of the biochip functionalized with anti-IgG and incubated with CB1 cells (c). Optical image after washes of the biochip lacking anti-IgG and incubated with A20 cells (d).
