“…Nanoparticles surface functionalisation plays a significant role in cellular uptake and producing cellular responses [33]. It is known that NPs have ability to form stable bonds with ligands contain sulphur atoms such as sulphides and thiols [34,35]. These ligands have a strong affinity toward the noble metals and tend to protect AuNPs through forming well-ordered, self-assembled monolayers (SAMs), which leads to good dispersion, facilitate characterisation, and high stability.…”

Biological application of nanoparticles (NPs) is a rapidly developing area of nanotechnology, providing new possibilities in the diagnosis and treatment of human diseases. Nowadays, NPs have shown abilities to be used as alternative treatment for difficult diseases. Therefore, it is important to understand NP chemistry, preparation, interaction and possible mechanisms involved in its interaction with cancer cells and bacterial membranes. This study reports comparison between Au, Ag and ZnO NPs, and discusses their toxicity and physicochemical properties. In addition, this work aims to review different strategies of surface modification and functionalization of colloidal nanoparticles.

In this work, the unusual ability of a ruthenium hydride catalyst, [RuHCl(PPh 3 ) 3 CO], supported on gold nanoparticle cored triazine dendrimers in the Suzuki−Miyaura cross-coupling reaction and also in the synthesis of diaryl ketones is reported. [Ru-H@AuNPs-TD] was characterized by Fourier transform infrared spectroscopy, CHNS, TEM, SEM, ICP, and TGA analyses. The ruthenium hydride catalyst was used as a heterogeneous catalyst for the C−C coupling reactions of aryl halides with phenylboronic acids, and the biphenyl derivatives were produced in good to excellent yields. On the other hand, this catalytic system was applied for synthesis of diaryl ketones by the reaction of phenylboronic acids with substituted benzaldehydes. Moreover, this catalyst can be well-dispersed in the reaction medium, conveniently separated from the reaction mixture, and reused several times without significant loss of its activity.
