Metals mofs loading mofs with Metal Nanoparticles for hybrid functions
European Journal of Inorganic Chemistry, 2010Co-Authors: Mikhail Meilikhov, Kirill Yusenko, Daniel Esken, Stuart Turner, Gustaaf Van Tendeloo, Roland A FischerAbstract:Metal–organic frameworks (MOFs) as well as porous coordination polymers (PCPs) are porous, organic–inorganic hybrid solids with zeolite-like structures and properties. Due to their extraordinarily high surface area and well defined pore structure MOFs can be used for the stabilization of Metal Nanoparticles with adjustable size. The embedded Metal Nanoparticles are still accessible for other reagents due to the high porosity of the MOF systems. This fact makes “Metal@ MOF” systems especially interesting for heterogeneous catalysis, gas storage and chemical sensing. This review compiles the cases of Metal Nanoparticles supported by or embedded into MOFs reported so far and the main aspects and

noble Metal Nanoparticles for biosensing applications
Sensors, 2012Co-Authors: Goncalo Doria, Bruno Veigas, Leticia Giestas, Carina Almeida, Maria Assuncao, Joao N Rosa, Joao Conde, Pedro V BaptistaAbstract:In the last decade the use of nanomaterials has been having a great impact in biosensing. In particular, the unique properties of noble Metal Nanoparticles have allowed for the development of new biosensing platforms with enhanced capabilities in the specific detection of bioanalytes. Noble Metal Nanoparticles show unique physicochemical properties (such as ease of functionalization via simple chemistry and high surface-to-volume ratios) that allied with their unique spectral and optical properties have prompted the development of a plethora of biosensing platforms. Additionally, they also provide an additional or enhanced layer of application for commonly used techniques, such as fluorescence, infrared and Raman spectroscopy. Herein we review the use of noble Metal Nanoparticles for biosensing strategies—from synthesis and functionalization to integration in molecular diagnostics platforms, with special focus on those that have made their way into the diagnostics laboratory.

Nonspherical noble Metal Nanoparticles: Colloid-chemical synthesis and morphology control
Advanced Materials, 2010Co-Authors: Tapan K. Sau, Andrey L A.l. Andrey L RogachAbstract:Metal Nanoparticles have been the subject of widespread research over the past two decades. In recent years, noble Metals have been the focus of numerous studies involving synthesis, characterization, and applications. Synthesis of an impressive range of noble Metal Nanoparticles with varied morphologies has been reported. Researchers have made a great progress in learning how to engineer materials on a nanometer length scale that has led to the understanding of the fundamental size- and shape-dependent properties of matter and to devising of new applications. In this article, we review the recent progress in the colloid-chemical synthesis of nonspherical Nanoparticles of a few important noble Metals (mainly Ag, Au, Pd, and Pt), highlighting the factors that influence the particle morphology and discussing the mechanisms behind the nonspherical shape evolution. The article attempts to present a thorough discussion of the basic principles as well as state-of-the-art morphology control in noble Metal Nanoparticles.

"Green" nanotechnologies: Synthesis of Metal Nanoparticles using plants
Acta Naturae, 2014Co-Authors: V V Makarov, A. J. Love, S. S. Makarova, Olga V. Sinitsyna, Siavash Iravani, Igor V. Yaminsky, Michael E Taliansky, Natalia O. KalininaAbstract:While Metal Nanoparticles are being increasingly used in many sectors of the economy, there is growing interest in the biological and environmental safety of their production. The main methods for nanoparticle production are chemical and physical approaches that are often costly and potentially harmful to the environment. The present review is devoted to the possibility of Metal nanoparticle synthesis using plant extracts. This approach has been actively pursued in recent years as an alternative, efficient, inexpensive, and environmentally safe method for producing Nanoparticles with specified properties. This review provides a detailed analysis of the various factors affecting the morphology, size, and yield of Metal Nanoparticles. The main focus is on the role of the natural plant biomolecules involved in the bioreduction of Metal salts during the nanoparticle synthesis. Examples of effective use of exogenous biomatrices (peptides, proteins, and viral particles) to obtain Nanoparticles in plant extracts are discussed.

green synthesis of Metal Nanoparticles using plants
Green Chemistry, 2011Co-Authors: Siavash IravaniAbstract:In recent years, the development of efficient green chemistry methods for synthesis of Metal Nanoparticles has become a major focus of researchers. They have investigated in order to find an eco-friendly technique for production of well-characterized Nanoparticles. One of the most considered methods is production of Metal Nanoparticles using organisms. Among these organisms plants seem to be the best candidates and they are suitable for large-scale biosynthesis of Nanoparticles. Nanoparticles produced by plants are more stable and the rate of synthesis is faster than in the case of microorganisms. Moreover, the Nanoparticles are more various in shape and size in comparison with those produced by other organisms. The advantages of using plant and plant-derived materials for biosynthesis of Metal Nanoparticles have interested researchers to investigate mechanisms of Metal ions uptake and bioreduction by plants, and to understand the possible mechanism of Metal nanoparticle formation in plants. In this review, most of the plants used in Metal nanoparticle synthesis are shown.
