Recently, fluorescent sensors have attracted considerable attention in their sensitive and selective determination of heavy metal ions the aqueous acidic medium due to advantages such as low cost easy handling. In this study, bathocuproine (BCP) compound was used a chemosensor. The selectivity sensitivity BCP been investigated against some biological environmental importance. results obtained f...

BACKGROUND In diabetes, protein function is altered by glycation, but the impact on the Fe3+ binding and antioxidant functions of transferrin (Tf) is largely unknown. The aim of the present study was to investigate the effects of glycation on the distribution of Fe3+ on the two Fe3+ -binding sites of Tf. METHODS In vitro glycation of Tf was accomplished by preincubation with glucose for 14 da...

Abstract The development of fluorophores emitting in the near-infrared spectral window has gained increased attention given their suitable features for biological imaging. In this work, we have optimised a general and straightforward synthetic approach to prepare small library near-infrared-emitting C-bridged nitrobenzodiazoles using commercial precursors. benzodiazoles low molecular weight neu...

In the present study, we carried out chemical synthesis and characterization of Fe3O4@PEG-Au as a magnetic nanocomposite in aqueous solution by chemical co-precipitation of Fe3+ and Fe2+ ions and encapsulated by poly (ethylene glycol) (PEG) in order to enhancing hydrophilicity, biocompatibility and immobilizing gold ions in the presence of NaBH4 as a reducing agent. Nanostructures were characte...

Two common waste materials, red mud and fly ash, were used to produce a new nano-hybrid adsorbent by heat treatment with alkali addition. The new zeolitic structure formation of the hybrid adsorbent was revealed using the BET surface area, XRD, and SEM analyses. This hybrid adsorbent was utilized to remove arsenic from synthetic and real waste waters by batch and column adsorption experiments. ...

UNLABELLED Iron and copper toxicity has been presumed to involve the formation of hydroxyl radical (*OH) from H2O2 in the Fenton reaction. The aim of this study was to verify that Fe2+-O2 and Cu+-O2 chemistry is capable of generating *OH in the quasi physiological environment of Krebs-Henseleit buffer (KH), and to compare the ability of the Fe2+-O2 system and of the Fenton system (Fe2+ + H2O2) ...

A simple chemosensor, 4-amino antipyrine linked bis-1,2,3-triazole, was synthesized via the “Click” approach using CuAAC method and characterized by FTIR, NMR, ESI-MS spectroscopy. The chemosensor upon ion...

Large amounts of hazardous and toxic substances in the environment require non-toxic, cheap, easy, rapid, sensitive methods for their detection. Blue luminescent graphene quantum dots (GQDs) were produced by electrochemical cleavage graphite electrodes followed gamma irradiation presence ethylenediamine (EDA). Modified able to detect metal ions (Co2+, Pd2+, Fe3+) due photoluminescence quenching...

1-(2-tryptanthrinylaminoacetoxy)-14-(1-pyrenecarboxy)-3,6,9,12-tetraoxatetradecane (T2NH-P5P) was synthesized as a fluorescent chemosensor for metal ions. We investigated the metal-ion recognition of T2NH-P5P by separately adding Mg(2+), Ca(2+), Ba(2+), Fe(2+), Fe(3+), Co(2+), Ni(2+), Cu(2+), Ag(+), Zn(2+), Cd(2+), Hg(2+), Al(3+), and Pb(2+) in an acetonitrile solution. When using excitation at...
