G-quadruplex facilitated turn-off fluorescent chemosensor for selective detection of cupric ion

A simple turn-off fluorescent method was utilized to quantitatively detect Cu(II) which can selectively quench fluorescent dye molecules. Addition of DNA G-quadruplex into the solution significantly magnifies the discrimination, lowers the limit of detection and broadens the linear response range.
