Abstract: In this study, we report a convenient, simple, economically viable and eco-friendly method for the synthesis of gold nanoparticles (AuNPs) with carboxymethyl gum kodagogu (CMGK). Carboxymethyl gum kondagogu is a nontoxic and renewable. It is used as reducing, stabilizing and capping agent for the synthesis of AuNPs without using any chemical reducing agent. The effect of various parameters such as concentration of HAuCl4 and CMKG and reaction time for the synthesis of AuNPs was studying

materials play the significant role in science and technology due to their unique shape, size, peculiar properties and potential applications. Metal nanoparticles, which possess considerable electronic, chemical and optical [1, 2] properties, are different from those of the bulk materials. Among the several metal nano particles gold (Au) nanoparticles have attracted rigorous consideration for their numerous applications in catalytic , sensing, imaging, diagnostics [3-6], tunable surface Plasmon resonance

advancement and its developments will be determined by the collective hard work of natural, physical, medical, engineering and related sciences. The materials in Nano scale can show different properties compared to what they exhibit on a macro scale. A nanoparticle by definition is, an ultra-refined particle that has all the dimensions in the Nano range i.e. from 1nm to 100

Introduction Cancer disease is one the most complicated fatal disease which scientists are looking for methods to either stop or cure this malady (Hook, Ptak, Farrell, Hinkal, Panaro and Grodzinski, 2010). Based on the cancer overlook disease, the cells are transformed and infected to cancer after a while and it starts to metastasize and proliferate (ibid). The cardinal issue is that how cancer may occur based on transformation of cells and genes. To illustrate that question, there are two factors

Nanocrystalline Materials Allison Bray, Harsha Rao, David Sanchez Abstract: Introduction: Nanoparticles are widely researched because of their size dependent properties that progressively differ from their bulk formations. Nano, meaning these particles are measured to be ~100 nm or less, are structures where the majority of the atoms are located at the surface of the particle. This gives nanoparticles a high surface area to volume ratio. In comparison to their bulk counterparts, when materials

As shown in Fig. 1, the bonds about 278 and 335 nm were related to the presence of polyphenolics as the antioxidant for green synthesis of nanoparticles, which assigned to the π → π* transitions [40]. The addition of the Safflower extract to the HAuCl4 solution was resulted in the Au3+ reduction and visual color change from light yellow to reddish brown is meaning the formation of Au-NPs. Therefore, this color change is due to Surface Plasmon Resonance (SPR) excitation the collective oscillation

Béalle and collaborators (2014) described the use of superparamagnetic iron oxide nanoparticles (ɣ-Fe2O3) to decorate catanionic vesicles. The vesicles were prepared by using cetyltrimethylammonium chloride and myristic acid and the nanomaterial was synthetized in aqueous alkaline solution by co-precipitation process of FeCl2 and FeCl3. The

When I began my undergraduate career, I had no inkling of what I wanted to do in the future. It was early on that I discovered my passion for chemistry, math and physics classes which galvanized my hunger for knowledge. In due time, I developed a proclivity for research that was stirred largely by my first mentor, Dr. Daniel Lambrecht, during an American Chemical Society meeting. I was so engrossed in his research on nanocatalysis and piezoelectrics that I walked up to him as soon as the meeting

A nanoparticle is the most basic component in the construction of a nanostructure. In general, the size of a nanoparticle spans the range between 1 and 100 nm. The properties of many conventional materials change when formed from nanoparticles. This is typically because nanoparticles have a greater surface area per weight than larger particles which causes them to be more reactive than other molecules. Self-assembly refers to the process by which nanoparticles or other distinct components spontaneously

oligomer-conjugated glycol chitosan as a carrier for tumor-targeted paclitaxel delivery, which was published in Journal of Controlled Release in 2013 (title: Enhanced drug-loading and therapeutic efficacy of hydrotropic oligomer-conjugated glycol chitosan nanoparticles for tumor-targeted paclitaxel delivery). Chitosan, a linear aminopolysaccharide composed of randomly distributed (1→4) linked D-glucosamine and N-acetyl-D-glucosamine units, is obtained by the deacetylation of chitin, a structural element in the
