An eco-friendly approach is described for the green synthesis of gold nanoparticles using catechin as a reducing and capping agent. The reaction occurred at room temperature within 1 h without the use of any external energy and an excellent yield (99%) was obtained, as determined by inductively coupled plasma mass spectrometry. Various shapes of gold nanoparticles with an estimated diameter of ...

Capping agents (organic ligands, polymers, surfactants, etc.) are a basic component in the synthesis of metal nanoparticles with controlled size and well-defined shape. However, their influence on the performances of nanoparticle-based catalysts is multifaceted and controversial. Indeed, capping agent can act as a “poison”, limiting the accessibility of active sites, as well as a “promoter”, pr...

Group II–VI cadmium sulfide nanoparticles (CdS NPs), a potential alternative to antibiotics, were synthesized using acetate [Cd(Ac)2] as precursor, sodium sulfate reducing agent, and starch capping agent through chemical precipitation techniques. The CdS NPs characterized different characterizing techniques; X-ray diffraction selected area electron patterns verify that the had cubic zinc blende...

Abstract Upscaling of nanoparticle fabrication by sputtering into an ionic liquid is shown for the example Cu. Long-time (24 h) a large amount (50 mL) 1-butyl-3-methylimidazolium bis-(trifluoromethylsulfonyl)imide [Bmim][(Tf) 2 N] yields approximately 1 g Cu nanoparticles (mean spherical diameter (2.6 ± 1.1) nm), stabilized in without agglomerations. Extraction from stabilizing was performed wi...

In this study, copper manganese oxide (CuMn2O4) nanoparticles were successfully synthesized by a simple sol-gel technique in the presence of lactose as the green capping agent. The lactose concentration effect on the crystalline size and magnetic properties of final products were systematically investigated. The structural, morphological, magnetic, and optical properties o...

Capping protein binds the barbed ends of actin filaments and nucleates actin filament assembly in vitro. We purified capping protein from Saccharomyces cervisiae. One of the two subunits is the product of the CAP2 gene, which we previously identified as the gene encoding the beta subunit of capping protein based on its sequence similarity to capping protein beta subunits in chicken and Dictyost...

Complementary and Alternative Medicine (CAM) is a rapidly evolving area of medicine and dentistry with a prevalence of use of 9 to 65% worldwide. Phytomedicines have come to occupy a place in dentistry and of these; propolis is a medicament that has been widely tested. Propolis has far reaching applications in dentistry, ranging from its use as a pulp capping agent to its role as a medium for a...
