Label-free and enzyme-free fluorescence detection of microRNA based on sulfydryl-functionalized carbon dots via target-initiated hemin/G-quadruplex-catalyzed oxidation
A dual-recognition carbon dots-based nanoprobe with controllable G-quadruplex release is developed for ratiometric fluorescence detection of pathogenic bacteria in a fast and precise way, which opens a promising avenue for...
Using a guanine-rich sequence (AGRO100) and N-methyl mesoporphyrin IX (NMM), a turn-on and label-free fluorescent Pb2+ sensor with high sensitivity and low background fluorescence was presented as a representative of five turn-on sensing systems.
A label-free and sensitive assay for apurinic/apyrimidinic endonuclease 1 was achieved based on isothermal amplification and G-quadruplex/ligand recognition.
A novel, label-free fluorescence detection method was proposed for the formation of the G-quadruplex DNAs based on placing two DNA-Ag NCs together to light-up fluorescence.
