Nano-particles are of great interest in fundamental and applied research. However, their accurate visualization is often difficult and the interpretation of the obtained images can be complicated. We present a comparative scanning electron microscopy and helium ion microscopy study of cetyltrimethylammonium-bromide (CTAB) coated gold nano-rods. Using both methods we show how the gold core as we...

The tracking of nano-scale biological markers in motion is a challenging project, that could lead to a better understanding of dynamics in biological systems. Since digital holography gives access to the whole light field in a volume from a single hologram [1, 2], this technique is suitable to reconstruct the field scattered by gold particles in three dimensions, and then determine their positi...

Understanding We produce size and shape controlled metal, semiconducting and hybrid nanocrystals by wet ...

Applying our photo technology, we succeeded in generating silver particles exceeding 10 μm by using 50 nm gold particles as catalysts, which are commonly used in commercially available influenza diagnostic kits. The amplified silver particles are 1,000 times easier to see than gold nano-particles. We have commercialized the influenza detection kit, named “FUJI DRI-CHEM IMMUNO AG cartridge FluAB...

Localized surface plasmon resonance (LSPR) biosensors are employed to detect target biomolecules which have particular resonance wavelengths. Accordingly, tunability of the LSPR wavelength is essential in designing LSPR devices. LSPR devices employing silver nano-particles present better efficiencies than those using other noble metals such as gold; however, silver nano-particles are easily oxi...

Highly active/stable inverse catalysts of nano-oxides on large gold particles are designed and tailored. For the gas-phase oxidation of alcohols as a model reaction, the experimental and theoretical results verify that the catalyst activity depends on the gold-oxide interface, and the anti-sintering feature of such an inverse structure endows the catalyst with high stability.

nano-encapsulated iron oxide in zirconium oxide-coated mica pigments are thermally stable,innocuous to human health, non-combustible, and they do not conduct electricity. they could beapplied in several industries such as thermoplastics, cosmetics, food packaging, children toys, paints,automobiles coating, security purposes, and banknotes. nowadays, they are highly desirable inceramic decoratio...

Introduction In this study, we describe the results of controlled synthesis and application of gold coated Fe3O4/SiO2 nano-shells combined with the optical property of gold for enhancement of selective photothermal interaction with cancerous cells based on the surface plasmon resonance (SPR) Phenomena. Materials and Methods Magnetite Nano-Particles (MNPs) were prepared by means of co-precipitat...

BACKGROUND The particles in the range of 1-100 nm are called nanoparticles. Gold nanoparticle is one of the most important metal nanoparticles with wide usage. OBJECTIVE This study investigated the effects of gold nanoparticles on sperm parameters and chromatin structure in mice. MATERIALS AND METHODS In this experimental study, 72 male bulb-c mice were divided into 9 groups including: 4 Sh...
