A real-time colorimetric and ratiometric fluorescent probe based on modulating the
intramolecular charge transfer (ICT) of the coumarin platform for selective detection of sulfite …

Due to its low cytotoxicity, high resistance to enzymatic degradation, and cellular
permeability, a DNA tetrahedron-based molecular beacon (DTMB) is designed for tumor …

A nanocomplex was developed for molecular sensing in living cells, based on the
fluorophore-labeled aptamer and the polydopamine nanospheres (PDANS). Due to the …

We designed and synthesized a new pH fluorescent probe, RCE, based on structural
changes of rhodamine dye at different pH values. The probe exhibits high selectivity, high …

The donor donor–acceptor (DD–A) FRET model has proven to have a higher FRET
efficiency than donor–acceptor acceptor (D–AA), donor–acceptor (D–A), and donor donor …

Conventional fluorophores usually undergo aggregation-caused quenching (ACQ), which
limits the loading amount of these fluorophores in nanoparticles for bright fluorescence …
