In this research, Graphene Oxide- Gold nanoparticles (AuNP/GO) were easily fabricated by a redox reaction between GO and chloroauric acid without using any additional reductant and then used to stabilize Pickering emulsions. (AuNP/GO) was investigated by FT-IR spectroscopy. The changes of parameters such as contact time, pH, Amoxicillin initial concentration and temperature were tested and inve...

Molecular self-assembly is an emerging subdiscipline of material science with important potential technological applications. Self-assembly is known in both molecular chemistry (for example, aggregation of molecules, molecular crystal or phase-separated polymers) and biology (for example, bilayer formation, protein folding and unfolding). Molecular self-assembly typically relies on amphiphilic ...

Abstract A continuous manufacturing platform was developed for the synthesis of aqueous colloidal 10–20 nm gold nanoparticles (Au NPs) in a flow reactor using chloroauric acid, sodium citrate and citric acid at 95 o C 2.3 bar(a) pressure. The use two-phase system – heptane as phase prevented fouling on walls, while improving residence time distribution. Continuous syntheses up to 2 h demonstrat...

Gold nanoparticles recently showed great interest for many uses including food, drug and medical applications. The algae Undaria sp. well known as wakame in South Asia are considered to be large edible brown algae. It provides nutritious source of dietary fiber, vitamin Bs mineral. present study aimed investigate the use green synthesis metallic gold nanoparticles. synthesized were characterize...

Gamma irradiation provides an alternative pathway to conventional gold nanoparticle synthesis because it is simple, fast, and economical. Here, we employed gamma at low doses (1–20 kGy) obtain nanoparticles (Au NPs) anchored onto graphene oxide (GO) sheets. GO was selected as a suitable platform for the nucleation growth of Au NPs its large surface area good dispersibility in water due presence...

In the quest for producing an effective clinically relevant therapeutic agent, scalability, repeatability, and stability are paramount. In this paper, gold nanoparticles (GNPs) with precisely controlled near infrared (NIR) absorption are synthesized by a single step reaction of HAuCl4 and Na2S2O3, without assistance of additional templates, capping reagents or seeds. The anisotropy in the shape...

A boost in the development of flexible and wearable electronics facilitates design new materials to be applied as transparent conducting films (TCFs). Although single-walled carbon nanotube (SWCNT) are most promising candidates for TCFs, they still do not meet optoelectronic requirements demanded their successful industrial integration. In this study, we proposed thoroughly investigated a appro...

Gold nanoparticles (AuNPs) have found widespread applications in life sciences. While synthesis of monodispersed AuNPs has been fairly convenient by using chemical reduction of chloroauric acid by sodium citrate, we found that AuNPs of high quality and high concentrations were not readily obtained via this method. As an example, we showed that monodispersed 13-nm AuNPs were readily synthesized ...
