英文摘要: Abstract(#br)This work describes how nanostructured thin films obtained from the self-assembly of block copolymers (BCPs) systems can be used as a nanoelectrode array (NEA) that can be programmed to specifically detect targeted molecules. Namely, poly(styrene-b-methacrylate) (PS-b-PMMA) thin films, after removal of PMMA phase, produced regular spaced 560 pores μm-2 with 16 nm of diameter. The nanopores were then chemically modified by the introduction of β-cyclodextrin (β-CD) molecules. By using the supramolecular interaction of β-CD and ferrocene (Fc), the pores could be programed by the introduction of molecules linked to Fc able to interact with target species. In the model system shown here, the linker had a biotin unit, aiming the detection of streptavidin. By changing the linker,...
