Some new compounds based on bis-benzimidazole moieties have been synthesized and characterized by IR and NMR spectroscopies. The ability of 3a in transition metal cation sensing such as Co2+, Ni2+, Zn2+, Mn2+, Fe2+ and Cu2+ have been investigated by Uv-vis and fluorescence spectroscopy in methanol solvent. The complexation constants and complex stoichiometry of Cu2+ have been determined. The ex...
Background and Aim: The material is always covered by proteins immediately upon contact with a physiological environment. Hemoglobin is the one of major blood proteins. The interaction between Hemoglobin and ligands such as nanoparticles is very important and may be cause structural changes on Hemoglobin. Materials and Methods: In this work we will address the effects of silver particles on th...
a novel quaternary ammonium-based cationic gemini surfactant (s6) having 1,6 di-bromo hexane as a spacer, have been used and its interaction with insulin in aqueous solution (ph, 7.40) was investigated by several methods including fluorescence spectroscopy, uv-vis spectroscopy, circular dichroism, dynamic light scattering, ζ-potential measurements, conductivity and transmission electron microsc...

New two nano- sized Schiff base complexes [M(L)], where L= 2, 2'-((1E, 1E')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and M=Cu or Zn, (a, b complexes) were synthesized by ultrasonic irradiation. These complexes were characterized by elemental analysis, molar conductivity, FT-IR, fluorescence emission, 1H NMR, field emission scanning electron spectroscopy...
