A versatile nanoarray electrode produced from block copolymer thin films for specific detection of proteins

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...
