Contrasting interactions of DNA-intercalating dye acridine orange with hydroxypropyl derivatives of β-cyclodextrin and γ-cyclodextrin hosts

Abstract

The present study demonstrates contrasting binding interactions of acridine orange dye with HPβCD and HPγCD hosts, always illustrating fluoresence “turn on” in the case of HPβCD and showing an interesting fluorescence “off/on switching” in the case of the HPγCD host.
