(a) Dual-signal-output nanochannels show a good specificity for glucose. Compared with glucose, the signal decrease of other monosaccharides is much lower. (b) Current change ratio and fluorescence intensity of dual-signal-output system for (4-(1,2,2-triphenylvinyl)phenylboronic acid (TPEB) and 1,4-benzenediboronic acid (DB). (c) Proposed mechanism and the chemical structure of the systems, ((1,2-diphenylethene-1,2-diyl) bis (1,4-phenylene)-1,1′-diboronic acid (TPEDB))+Glu, without Glu, TPEB+Glu and DB+Glu, on the walls of the nanochannels.
