A radical approach for fluorescent turn 'on' detection, differentiation and bioimaging of methanol.

چکیده
A simple Schiff base (RC) has been explored as a smart example of fluorescent material for the selective detection, differentiation and bioimaging of methanol. The nucleophilic attack of methanol on the cyclic control unit of RC leads to its opening and formation of a highly fluorescent moiety, RO. The RC displays a good sensitivity for MeOH with a detection limit of 0.042 wt% in water.

Design of a Fluorescent Sensor Based on the Polydopamine Nanoparticles for Detection of Gallic Acid
Background: Gallic acid (GA) is one of the polyphenolic compounds with antioxidant, antimicrobial and radical scavenging activities, which plays a main role in human health against cancer and cardiovascular diseases. GA concentration can be quantitatively measured in food, medicinal plants and body fluids. Materials and Methods: In this study, MnO2 nanosheets were prepared by reducing potassium...
متن کاملAn amine/imine functionalized microporous MOF as a new fluorescent probe exhibiting selective sensing of Fe3+ and Al3+ over mixed metal ions
Nowadays metal-organic frameworks with multiple luminescent centers are very fascinating as multifunctional luminescent material because of their luminescence properties, which could be systematically tuned by deliberate use of organic ligands and metal ions. In this research, we explored a microporous mixed-ligand MOF for highly selective and sensitive detection of metal ions. A two-fold inter...

Recently, the fluorometric detection of biomacromolecules has attracted much attention. In this paper, we report the development of two new techniques utilizing the chemical properties of amino acids or peptides: 1) a fluorescence assay for serine/threonine kinase activity; and 2) "turn-on" fluorescent probes for protein labeling, which could be useful for bioimaging. To develop the novel kinas...

Since neurotransmitters significantly influence the brain activity, our understanding of the human brain will remain imperfect until all aspects relating to them become clear. One of the key challenges in neuroscience researches and therapies is elucidating the mechanisms by which the neurotransmitter release take place and is regulated in quantity and in time. Despite the enormous number of st...
متن کاملA Novel Dicyanoisophorone-Based Ratiometric Fluorescent Probe for Selective Detection of Cysteine and Its Bioimaging Application in Living Cells.
A selective and ratiometric turn-on fluorescent probe was designed and synthesized by using a novel dicyanoisophorone-based derivative and acrylate moiety. The probe displayed high stability and good selectivity to cysteine (Cys) over homocysteine (Hcy) and glutathione (GSH). It also exhibited rapid response to Cys within 180 s. Most importantly, the fluorescence intensity ratio at 590 and 525 ...
