Sensitive fluorescence detection of lysozyme using a tris(bipyridine)ruthenium(ii) complex containing multiple cyclodextrins†
Abstract
A new series of photoactive metallocyclodextrins with increased fluorescence intensity upon binding with ssDNAs/aptamers has been demonstrated to sensitively and selectively detect lysozyme. The detection mechanism relies on the formation of an aptamer–lysozyme complex, which leads to reduction of fluorescence intensity.
