A highly selective and ultrasensitive ratiometric far-red fluorescent probe for imaging endogenous peroxynitrite in living cells

A highly selective colorimetric and long‐wavelength fluorescent probe for the detection of Hg2+

“…Specifically, the colorimetric fluorescence probes stand out from numerous detection methods because they allow the target analytes to be detected using the naked‐eye, therefore needing no help from other sophisticated instruments . Also, they have the advantages of simple synthesis, high selectivity and sensitivity . Due to the long‐wavelength the fluorescent probe possesses several merits, such as more obvious color change, better tissue penetration, and minimum interference from background auto‐fluorescence by biomolecules, therefore it has attracted intense interest of researchers.…”

Combination of Two Colorless Fluorophores for Full-Color Red-Green-Blue Luminescence

“…Organic full-color fluorescent materials have aroused broad interest owing to their application prospects in elaborate polychrome displays, − chemical sensors, − biological tracers, and imaging. − Blending three distinct primary colors (including red, green, and blue) while maintaining their emission sources independent of each other is the effective method for generating full-color fluorescence. − This strategy has been widely adopted to explore full-color materials because it only needs to develop luminophores with various structures to adjust and control emissions covering diverse visible-light spectral regions. During the past decades, to achieve full-color emission including white light emission, enormous research efforts have been paid on the fabricate tuning of the mixing ratio of fluorescent materials. − However, compared with bulk pixels, reproducing colors on a molecular scale by simply blending distinct red-green-blue (RGB) chromophores is defective because of the inescapable energy transfer between them.…”

Novel dual-site fluorescent probe for monitoring cysteine and sulfite in living cells

“…The use of uorescent probes has become popular because of their noninvasiveness, high sensitivity and real-time detection. [12][13][14][15][16] Various uorescent probes have been designed and reported for the detection of Cys in vitro and in vivo, and have been used to simultaneously distinguish cysteine/ homocysteine, glutathione, and hydrogen sulde in living cells, [17][18][19][20][21][22][23][24][25] and ratiometric uorescent probes have been used to quantify cysteine. [26][27][28][29][30] Our group previously designed and synthesized several uorescent probes for sensitively and selectively detecting Cys over other biothiols in living cells and mice.…”
