Application of Carbon Nanoparticles as Fluorescent Quenchors in Biochemistry

Abstract

carbon nanoparticles (CNPs ) prepared by electrochemical oxidation method possesses high surface activities, and based on strong affinities between water-soluble CNPs and fluorescent molecules, the mechanisms of fluorescence quenching towards Conjugated Polymers (CPs) was discussed, and CNPs could acted as a nanoquenchor for biochemistry application, such as detection of DNA molecules and other biomolecules by the similar way.

“…The usage of this material to label the HMC has incomparable advantages [9][10][11][12][13]. It is well known that due to the π-π interaction between the fluorescent dyes and carbon walls, the fluorescence of common fluorescent organic molecules can be quenched by graphene through photoinduced electron transfer [14][15][16][17]. Therefore, to tackle this problem, carbon materials are usually coated first with another material in order to avoid direct contact between the carbon and fluorescent dye.…”
