Turn on Fluorescent Probes for Selective Targeting of Aldehydes
Two different classes of fluorescent dyes were prepared as a turn off/on sensor system for aldehydes. Amino derivatives of a boron dipyrromethene (BDP) fluorophore and a xanthene-derived fluorophore (rosamine) were prepared. Model compounds of their product with an aldehyde were prepared using salicylaldehyde. Both amino boron dipyrromethene and rosamine derivatives are almost non-fluorescent i...
متن کاملReactivity-based fluoride detection: evolving design principles for spring-loaded turn-on fluorescent probes.
A covalently triggered fluorescence turn-on detection scheme has been implemented for a tris(N-salicylideneamine)-derived dynamic fluorophore. Selective cleavage of strategically placed Si-O bonds by fluoride ion induces spring-loaded conformational transitions that are tightly coupled to fluorescence enhancement.
متن کاملCarbon nanodots as ligand exchange probes in Au@C-dot nanobeacons for fluorescent turn-on detection of biothiols.
Au nanoparticle-carbon dot core-shell (Au@C-dot) nanocomposite was synthesized in aqueous medium at room temperature using the carbon dots as reducing agents themselves. The carbon nanodots also function as an effective stabilizer by forming a thin layer surrounding Au nanoparticles (Au NPs) similar to self-assembled monolayers. Ligand exchange with thiol containing biomolecules resulted in the...
متن کاملA turn-on fluorescent solid-sensor for Hg(II) detection
A rhodamine organosilane derivative (Rh-UTES) has been obtained by one-pot synthesis. The chemical structure of Rh-UTES was confirmed by nuclear magnetic resonance (NMR) and infrared (FTIR) techniques. To obtain an inorganic-organic hybrid sensor, Rh-UTES was covalently immobilized on a porous silicon microcavity (PSiMc) via triethoxysilane groups. The attachment of the organic derivative into ...
