Articles Related to gold nanoparticles
We report here on new optic and small-angle X-ray scattering (SAXS) measurements concerning the formation of the dispersions from double-stranded (ds) DNA molecules, doped with negatively charged gold nanoparticles (nano-Au). The nano-Au fixation nearby the surfaces of linear ds DNA in solution of high ionic strength (0.3 M NaCl) and subsequent phase exclusion of (ds DNA-nano-Au) complexes from solution containing poly(ethylene glycol) results in decrease in the amplitude of abnormal negative band in the circular dichroism spectra of the formed cholesteric liquid-crystalline dispersions (CLCD).
Complete Green Synthesis of Gold Nanoparticles using Laser Ablation in Deionized Water Containing Chitosan and Starch
In this paper we report our results on the green synthesis of nontoxic, stable, and small size gold nanoparticle suspensions. We used the single and two-beam laser to ablate a gold target submerged in deionized water containing chitosan or starch as the stabilizing agent. Since both chitosan and starch are biodegradable and biocompatible, use of these natural polymers for gold nanoparticle protection and stabilization does not introduce any environmental toxicity or biological hazards.
Cancer is a highly heterogeneous disease characterised by continuous uncontrolled growth and expansion of abnormal cells. In general, in tumor cells the signalling pathways regulating cellular processes, as cell growth and division and cell to cellcommunication result strongly altered.
Synthesis and Characterization of Nanocomposites Using the Nanoscale Laser Soldering in Liquid Technique
We have synthesized Au/CuO and Au/ZnO nanocomposites using the laser soldering technique. The process was carried out by irradiating a solution containing Au-CuO and Au-ZnO nanoparticles using 532 nm laser pulses of 0.1 J/cm2 continuously for 20 minutes.
