In this work, we report a green and simple strategy for the in situ growth of surfactant-free Au nanoparticles (Au NPs) on nitrogen-doped graphene quantum dots NPs-N-GQDs). The formation hybrid was achieved by just mixing N-GQDs HAuCl4·4H2O without addition any other reductant surfactant. High-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), photoelectron spectroscopy (XPS) characterizations clearly showed with predominantly exposed (111) facets which can provide...

Subnanometer-sized copper nanoclusters were prepared by a one-pot procedure based on wet chemical reduction. The structural characteristics of the 2-mercapto-5-n-propylpyrimidine-protected nanoclusters, Cun (n ≤ 8), determined mass spectrometry.

We have investigated the effect of folding DNA aptamers on colloidal stability gold nanoparticles (AuNPs) to which an aptamer is tethered. On basis studies two different (adenosine and K+ aptamer), we discovered a unique stabilization associated with folding: AuNPs folded structures are attached more stable toward salt-induced aggregation than those tethered unfolded aptamers. This significant when spacer was incorporated between AuNP or lower surface graft densities were used. The...
Water-soluble cupric oxide nanoparticles are fabricated via a quick-precipitation method and used as peroxidase mimetics for ultrasensitive detection of hydrogen peroxide glucose. The water-soluble CuO show much higher catalytic activity than that commercial due to their affinity peroxide. In addition, the as-prepared stable over wide range pH temperature. This excellent stability in form aqueous colloidal suspensions makes application easier systems. A colorimetric assay glucose has been...

Metal nanoclusters (NCs) as a new type of fluorescent material have been extensively explored because their attractive set features such ultrafine size, low toxicity, and excellent photostability. However, little progress has made in producing water-soluble, homogeneous, ultrabright metal NCs.
