Room-Temperature Phosphorescence Chemosensor and Rayleigh Scattering Chemodosimeter Dual-Recognition Probe for 2,4,6-Trinitrotoluene Based on Manganese-Doped ZnS Quantum Dots

Insecticide as a precursor to prepare highly bright carbon dots for patterns printing and bioimaging: A new pathway for making poison profitable

“…Because transition metal and rare-earth ions are deeply rooted in the host lattice of doped QDs and upconversion nanoparticles, respectively, the dissolved oxygen in solution is prevented from contacting with the excited triplet state, resulting in the effective phosphorescence [59,60]. Both FTIR and XPS spectra signal triplet-producing aromatic ring and triplet-promoting bromine in insecticide-based C-dots.…”

“Turn off–on” phosphorescent biosensors for detection of DNA based on quantum dots/acridine orange

“…Recently, room-temperature phosphorescence (RTP) QDs detection has attracted much attention and has been widely applied into sensors, especially biomolecular sensors [16][17][18][19][20][21][22][23][24][25][26][27]. Owing to the longer lifetime of phosphorescence, RTP QDs detection provides high reliability and stability without interference from autofluorescence or scattered light [16,[18][19][20].…”

“…In additional, the detection selectivity is further enhanced as phosphorescence is less common than fluorescence [17]. The development of RTP sensors shows bright prospect [16][17][18][19][20][21][22][23][24][25][26][27] because any other complicated pretreatments are required for the developed biosensors [18,20,25]. However, there is rare research about the "Turn off-on" of RTP sensors.…”

The dynamics of a novel method coupling high‐performance liquid chromatography with resonance Rayleigh scattering

“…It was investigated that some analytes could form an ion-association complex with molecular recognition probe so that it could produce stronger scattering signal in mobile medium. Thus, the foundation has been established to develop new analytical methods for the determination of inorganic ions [7], organic compounds [8], biological macromolecules [2], pharmaceuticals [9], etc. However, if several compounds exist simultaneously, the RRS method will not work effectively.…”
