“…Some studies have shown that the synthesis of nanoparticles with the technique is generally quite fast, simple, and energy efficient compared with conventional hydrothermal synthesis. [17,18] To the best of our knowledge, there are no reports on the preparation of highly stable and uniformly sized colloidal carbon nanospheres by the technique.…”

A rapid microwave‐hydrothermal method has been developed to prepare monodisperse colloidal carbon nanospheres from glucose solution, and gold nanoparticles (AuNPs) are successfully assembled on the surface of the colloidal carbon nanospheres by a self‐assembly approach. The resulting AuNP/colloidal carbon nanosphere hybrid material (AuNP/C) has been characterized and is expected to offer a promising template for biomolecule immobilization and biosensor fabrication because of its satisfactory chemical stability and the good biocompatibility of AuNPs. Herein, as an example, it is demonstrated that the as‐prepared AuNP/C hybrid material can be conjugated with horseradish peroxidase‐labeled antibody (HRP‐Ab2) to fabricate HRP‐Ab2‐AuNP/C bioconjugates, which can then be used as a label for the sensitive detection of protein. The amperometric immunosensor fabricated on a carbon nanotube‐modified glass carbon electrode was very effective for antibody immobilization. The approach provided a linear response range between 0.01 and 250 ng mL−1 with a detection limit of 5.6 pg mL−1. The developed assay method was versatile, offered enhanced performances, and could be easily extended to other protein detection as well as DNA analysis.

“…In previous work, we proposed a mechanism for the formation of CuInSe 2 (CIS) and CuInTe 2 (CIT) nanoparticles. [14] The proposed mechanism was based on the fact that the reduced metallic particles react with a second metallic element and with the chalcogenide under microwave irradiation in order to form a ternary chalcogenide compound. For the abovementioned compounds, CIS and CIT, the additional metallic element was indium.…”

The microwave-assisted polyol method has been applied to the preparation of nanosized Cu 2 SnSe 4 . Cheap materials such as CuCl (or CuCl 2 ·2H 2 O), Sn and Se were used as starting materials. Polyethylene glycol (PEG) is the only solvent in which the reaction takes place and the materials did not react in ethylene glycol, tri-, or tetraethylene glycol. Mössbauer spectroscopic measurements revealed a single doublet whose isomer shift of 1.81 mm/s is typical of that

“…The use of domestic multimode microwave (Gabriel et al 1998;Grisaru et al 2003;Harpeness and Gedanken 2004) or single-mode microwave ovens (Kadirvelu et al 2000;Katsuki and Komarneni 2003) for the fabrication of inorganic nanomaterials is becoming a common technique. The main advantage of this method when compared to other synthetic nanoparticle techniques is the short reaction time.…”

Pollution of water bodies with heavy metal ions is a major worldwide environmental problem. The objective of this study was to elucidate the mechanism in which metallic ions are adsorbed and reduced to metallic nanoparticles onto plant materials using microwave radiation. In this research, we have fabricated metallic silver and lead nanoparticles from their corresponding ions using the aquatic plants Azolla filiculoides and Pistia stratiotes (since identical results are obtained for both plants, the emphasis will be on the Azolla) under microwave radiation. Our data show that metallic silver and metallic lead nanoparticles were completely removed from the polluted solution and were embedded in the A. filiculoides surface after 5 min of microwave reaction. It was also found that, for both metals, reduction of the metallic ions was accomplished by the plant matrix without the need of an external reducing agent. Most of the particles had a spherical shape within the 10-50 nm size range. Mass balance data clearly indicate that most of the silver particles were found on the surface of the plant and not in the clean water. Pectin and α-glucuronic acid did not reduce the silver or lead ions under microwave radiation. We therefore hypothesize that perhaps the proteins or sugar alcohols in the plant matrix were serving as the reducing agents. We believe that this technique in which adsorption and reduction are combined using microwave radiation can be applied for removing and recycling metallic ions from contaminated water and industrial wastewater.
