Demonstrates enhanced detection of G-quadruplex DNA, suggesting improved imaging methods.
A collection of oxyethylene-bridged thiazole orange dimers with systematically varied spacer lengths was synthesized for the fluorogenic detection of higher-order DNA structures. Spectroscopic studies reveal that spacer length critically regulates binding and signal amplification. TO4TO exhibits maximum fluorescence turn-on and selectively detects parallel G-quadruplex and quadruplex-duplex hybrid DNA with nanomolar sensitivity. Notably, it can serve as a cellular imaging probe, demonstrating that spacer engineering is an effective strategy for fluorogenic detection and imaging of higher-order DNA structures.
