Current methods for synthesis of gold nanoparticles

Abstract

Metal nanoparticles, such as nanoparticles synthesized using gold, have numerous uncommon chemical and physical properties due to the effects of their quantum size and their large surface area, in comparison with other metal atoms or bulk metal. Gold nanoparticles (GNPs), in particular, are very attractive because of their size and shape-dependent properties. Metal nanoparticles have gathered extensive attention due to their uncommon properties and promising applications in photonics, electronics, biochemical sensing, and imaging. This review covers recent advances in the synthesis of GNPs.

Comparison, synthesis and evaluation of anticancer drug-loaded polymeric nanoparticles on breast cancer cell lines

“…The absorption bands at 1528 cm  1 are attributed to the N-H bending vibrations, which proved the construction of PCL-PEG-PCL triblock copolymers. The terminal hydroxyl groups in the copo-(CH2Cl2) in the presence of a triple molar ratio of triethylamine, at room temperature, and stirred at 400 rpm on a magnetic/heater stirrer for 6 h , Chung et al 2014, Zohre et al 2014, Dadashzadeh et al 2014, Rahimzadeh et al 2014, Herizchi et al 2014, Kafshdooz et al 2014, Sohrabi et al 2014, Shafiei et al 2014, Dadashzadeh et al 2014, Majidi et al 2014). Then, 10 mg of PEG-PCL copolymer was added and emulsified into the mixture obtained, and stirred at 400 rpm until it was completely emulsified.…”

“…Thus, 100 mg of the copolymer was emulsified in the mixture, using probe sonication at 10 W for 45 s. The mixture obtained (w/o emulsion) was added to an aqueous solution of sodium cholate (6 ml), and was then probe sonicated at 18 W for 1 min. The mixture obtained (w/o/w emulsion) was gently stirred at room temperature until the evaporation of the organic phase was complete , Chung et al 2014, Zohre et al 2014, Dadashzadeh et al 2014, Rahimzadeh et al 2014, Herizchi et al 2014, Kafshdooz et al 2014, Sohrabi et al 2014, Shafiei et al 2014, Dadashzadeh et al 2014, Majidi et al 2014). To prepare doxorubicin-loaded PEG-PCL, 3 mg of doxorubicin hydrochloride was emulsified in 2 ml of dichloromethane …”

Single and multiple detections of foodborne pathogens by gold nanoparticle assays

“…Copyright © 2016 Multidisciplinary Digital Publishing Institute When ionic liquids are used in the sonochemical synthesis of GNPs it becomes possible to synthesize very small NPs with a fast rate of reaction, however the size distribution is often wide. Increased control over size distribution and shape can be achieved through the addition of surfactants (Herizchi et al, 2016).…”

Gold Nanoparticles for Diagnostics: Advances towards Points of Care

“…Therefore, it can be finely-tuned through the manipulation of these variable using various synthesis routes (for a review see [7] and references therein) or dispersion media [8]. LSPR results from the absorption and the scattering of the AuNPs, and the relative weight of each to the overall LSPR can be controlled through the size and shape of the AuNP.…”
