Red fluorescent luminogen from pyrrole derivatives with aggregation-enhanced emission for cell membrane imaging.
A dye emitted red fluorescence with aggregation-enhanced emission properties was reported here. It can be utilized to specifically recognize the cell membrane of MCF-7 and 293T cell lines during bio-imaging.
متن کاملAggregation-Induced Emission for Highly Selective and Sensitive Fluorescent Biosensing and Cell Imaging
Fluorescent bioprobes are powerful analytical tools for studying biological activities in living systems. Fluorogens with aggregation-induced emission (AIE) characteristics have recently emerged as a new class of fluorescent bioprobes for biosensing and cell imaging. As discovered by Tang, AIE fluorogens are nearly nonemissive in molecular states with their intermolecular rotations being not re...
متن کاملFluorescent "light-up" bioprobes based on tetraphenylethylene derivatives with aggregation-induced emission characteristics.
Aggregation in poor solvents and complexation with calf thymus DNA and bovine serum albumin turn "on" the fluorescence of tetraphenylethylene derivatives, due to the restriction of intra-molecular rotations of the dyes in the aggregates and complexes.
متن کاملA novel diketopyrrolopyrrole (DPP)-based [2]rotaxane for highly selective optical sensing of fluoride.
A novel [2]rotaxane based on an orthogonal H-bonded motif and 3,6-di(thiophen-2-yl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione (DPP) with controlled topicity was successfully constructed, displaying excellent stimulated responses toward anion and solvent polarity. The preorganized host selectively recognized F(-) with high optical sensitivity and reversibility via enhanced positive cooperativity and...
متن کاملFluorescent light-up probe with aggregation-induced emission characteristics for in vivo imaging of cell apoptosis.
In this paper, a new live-cell permeable, fluorescent light-up probe comprised of a hydrophilic caspase-specific Asp-Glu-Val-Asp (DEVD) peptide and a hydrophobic tetraphenylethene pyridinium unit has been developed for in vivo cell apoptosis imaging and drug screening. The probe shows a specific light-up response to activated caspase-3/7 with a high signal-to-background ratio. The significant f...
