In this paper, we have described the size-controlled synthesis of gold nanoparticles based on the reduction of Au3+ (HAuCl4 ) using molybdophosphoric acid (H3[PMo12O40 ], HPMo) under UV-irradiation. In the process, HPMo plays the role of photocatalyst, reducing agent and stabilizer and propan-2-ol acts as a sacrificial agent. This method allows the synthesis of uniform hexagonal nanoparticles w...

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...

Objective(s):The current systematic study has reviewed the therapeutic potential of gold nanoparticles as nano radiosensitizers for cancer radiation therapy.   Materials and Methods: This study was done to review nano radiosensitizers. PubMed, Ovid Medline, Science Direct, SCOPUS, ISI web of knowledge, Springer databases were searched from 2000 to September 2013 to identify appropriate studies....

This present work reports an ecofriendly approach for the synthesis of gold nanoparticles (Au NPs) using aqueous stem extract of Periploca aphylla as a reducing and stabilizing agent, has been discussed. This approach is simple, cost-effective and stable for a long time, reproducible at room temperature and in an eco-friendly manner to obtain a self-assembly of Au NPs. Two parameters were optim...

A protocol for cluster size distribution analysis was developed in order to parametrize local two-dimensional (2D) order in a quantitative manner, using mean cluster sizes and fractional hcp cluster formation (fhcp). Cluster size analysis was performed on 2D arrays of Au nanoparticles encapsulated in resorcinarene tetrathiol, which were organized into close-packed films at aqueous interfaces. T...

It is now well-known that the size, shape, and composition of nanomaterials can dramatically affect their physical and chemical properties, and that technologies based on nanoscale materials have the potential to revolutionize fields ranging from catalysis to medicine. Among these materials, anisotropic particles are particularly interesting because the decreased symmetry of such particles ofte...

The author describes this small book as a ' paper' and this is a more or less correct definition because it is by no means a finished presentation of the subject. It is composed of two parts. Part I is devoted to a brief description of the general physical characters of certain tribes in the Gold Coast and the diets they consume. This is necessarily incomplete as proper analysis of the various ...

A simple, sensitive gold nanoparticle (GNP)-based dot-blot immunoassay has been developed for detecting Alzheimer's disease related β-amyloid peptide 1-42 (Aβ(1-42)) down to a 50 pg mL(-1) level in aqueous solution. Practical samples (cerebrospinal fluid (CSF), cell culturing mediums and cell lysates) have been used to demonstrate the ability of the assay.
