Multivalent nanostructures are becoming an increasingly important player in the self-assembly of supramolecular lattices. Understanding the role that shape plays in the coordination of the assemblies is crucial for the functional response of the material. We develop a simple design rule for the assembly of multivalent Au triangular nanoprisms into 1-D ordered arrays based on both the length of ...

a simple, precise, inexpensive and sensitive voltammetric method has been developed for the determination of gemifloxacin mesylate (gem) in the presence of tween 80 in the bulk, farmaceutical dosage forms and human urine at gold nanoparticles modified carbon paste electrode (gncpe). the electrochemical behavior of gem has been investigated by using cyclic voltammetry (cv) and differential pulse...

in this research, gold nanoparticles were synthesized and functionalized by the antibody of aflatoxins. the quenching of the fluorescence of excitation emission matrices (eem) of two type of aflatoxins (b1, g1), provoked by the gold nanoparticles, was studied by principal component analysis (pca) and multivariate curve resolution with alternating least squares (mcr-als). these aflatoxins show q...

due to the binding of the –coo- group with the mercury (ii), gold nanoparticlesfunctionalized with glutathione can self-assemble to form a supermolecular network in the hac-naac buffer solution. the aggregation of functionalized gold nanoparticles and mercury (ii)caused the shift of maximum absorption peak of the uv-vis spectrum from 520 nm to 609 nm.based on this principle, a simple spectropho...

today, use of nanotechnology for cancer therapy is an active field of research. early detection, accurate diagnosis, and individual treatment are the aims which cause nanotechnology as an attractive area for research. among metallic nanomaterials, gold nanostructures have unique properties which make them remarkable candidates for biomedical approaches. surface plasmonic resonance (spr) effect ...

introduction: helicobacter pylori, as an etiologic cause of peptic ulcers and gastric cancer, should be tested and treated. the true state of infection can only be detected by isolation of gastric biopsies through the invasive method of gastroscopy. however, there are several non-invasive methods for detection of infection, the most common of which is serology. methods: here we have evaluated t...

The title compound, [Au(C(8)H(7)ClNOS)(C(18)H(15)P)], is characterized by a linear S,P-donor set with a small deviation from the ideal linearity [S-Au-P = 175.14 (5)°] due to the close approach of the O atom to the Au atom [Au⋯O = 2.882 (3) Å]. Loosely associated dimers are formed in the crystal structure through C-H⋯O inter-actions.

The Au atom in the title compound, [Au(C(8)H(7)ClNOS)(C(18)H(15)P)], exists within a slightly distorted linear geometry defined by an S,P-donor set [S-Au-P angle = 174.61 (4)°], with the distortion related to a short intra-molecular Au⋯O contact [2.988 (3) Å]. In the crystal structure, mol-ecules are arranged into supra-molecular chains along the b axis by C-H⋯π inter-actions.
