Fig. 7

On the bottom left a schematic diagram is shown for the sensing device, where a LbL film containing antigens in proteoliposomes is deposited onto an interdigitated electrode. The other panels bring capacitance versus frequency curves for three electrodes immersed into 10⁻⁵ mg/mL antibody solutions, as indicated. Note that distinction between the samples is much superior with the electrode containing a 5-bilayer LbL film of PAMAM/proteoliposome (lower right). Reproduced with permission from Ref. [72]
