Product Name

Name:Au Nanoparticles


Product Overview

Gold nanoparticles can also be referred to as nano gold colloids, which are a colloidal system formed by dispersing nano gold particles in a solution. The commonly used preparation methods for nano gold colloids include sodium citrate reduction chloroauric acid method, also known as seed growth method, electrochemical synthesis method, etc. The color of nano gold colloids changes with the size of gold nanoparticles. Generally speaking, the larger the diameter of gold nanoparticles, the longer the wavelength of light absorbed by their solution shifts towards longer wavelengths, and the particles will exhibit complementary colors to the absorbed light.


Technical Parameter

 

Form:orange-red,red,purplish-red solution etc

Solvent:water


Product Features

 

The gold nanoparticles provided by Xianfeng Nano are prepared by seed growth method and have different particle sizes to choose from.

Optical properties: They have surface plasmon resonance effects and can exhibit specific absorption and scattering spectra, which make them widely used in fields such as biological detection and optical imaging.

Color: The color of nano gold colloids varies with the size of the gold particles.

Good stability: The chemical properties are relatively stable.

Biocompatibility: Low toxicity to living organisms, which makes it highly favored in biomedical fields such as drug delivery and biomarkers.

Catalytic performance: can act as a catalyst and play a role in some chemical reactions.


Application Fields

 

Gold nanoparticles have a wide range of applications, including but not limited to the following aspects:

Biomedical field:

Disease diagnosis: such as using its surface plasmon resonance characteristics for immune analysis, biosensor detection, etc.

Drug delivery: Loading drugs and achieving targeted delivery.

In the fields of chemistry and materials science:

Catalyst: exhibits excellent catalytic performance in some chemical reactions.

Nanomaterial preparation: as a fundamental material for constructing other nanostructures.

In the field of optics:

Optical components: used for manufacturing new optical sensors, filters, etc.

Surface enhanced Raman scattering (SERS): significantly enhances Raman signals for analysis and detection.

In the field of electronics:

Electronic components: can be used to prepare nanoelectronic devices.

In the field of environmental monitoring:

Pollutant detection: has a sensitive response to specific pollutants.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Great upgrade compared to others
Color: Rechargeable with Storage Stand and Box - Black
This frother is far superior to other hand held versions we’ve owned. The attachments are much sturdier and don’t bend as easily (which made the others we’ve purchased quite useless). Rechargeable battery seems to last longer and provides plenty of power even on the lowest setting. The little wisk easily whips up eggs for a morning omelette and frothing cream and mixing powder into drinks are super easy with the other attachments. Finally, the stand is actually sturdy and balanced enough that it doesn’t easily tip over.
