Product Overview

CTAB modified gold nanorods (AuNRs) are a special type of nanomaterial in ethanol solvent. In ethanol, CTAB modified gold nanorods can form a uniform dispersion, which helps to maintain the dispersibility and stability of the nanorods. The modification of CTAB helps to protect gold nanorods from oxidation and aggregation, thereby improving their stability in different chemical environments.

Technical Parameter

Form :Light pink despersion

Aspect ratio:~4

Product Features

Surfactant Stability: CTAB (Hexadecyltrimethylammonium bromide), as a surfactant, forms a stable dispersion system through the negative charge interaction between its cationic head group and the surface of gold nanorods. Solubility in ethanol: Ethanol is a polar solvent that can dissolve CTAB modified gold nanorods, forming a uniform nanosuspension. Optical properties: Gold nanorods have unique optical absorption and scattering properties, especially the surface plasmon resonance (SPR) effect, which gives them special optical responses in the visible and near-infrared regions. Size and shape dependence: The SPR peak position of gold nanorods is closely related to their size and shape, and can be regulated by adjusting these parameters. Chemical stability: CTAB modification helps protect gold nanorods from oxidation and aggregation, improving their stability in different chemical environments. Catalytic activity: The surface plasmon effect of gold nanorods can enhance their catalytic performance, making them highly active in certain chemical reactions. Environmental sensitivity: The optical properties of gold nanorods are sensitive to environmental conditions such as pH, temperature, and ionic strength, which provides possibilities for environmental monitoring and sensor development. The Convenience of Ethanol Solvent: Ethanol, as a widely used solvent, is volatile and easy to handle and remove, which provides convenience for the subsequent processing and application of gold nanorods.

Application Fields

Biosensing: The surface plasmon resonance properties of gold nanorods give them potential applications in the construction of biosensors for detecting trace molecules. Biological imaging: Gold nanorods have strong scattering in the near-infrared band and can be used as contrast agents for biological imaging, especially in light scattering imaging. Catalysis: Gold nanorods can serve as catalysts or catalyst carriers to improve the efficiency of catalytic reactions, especially under conditions of light irradiation. Sensors: The surface enhanced Raman scattering (SERS) effect of gold nanorods makes them applicable in the field of sensors for detecting biomolecules, ions, etc. Optical components: Gold nanorods can be used to manufacture near-infrared filters, nonlinear optical components, polarizers, etc. Information storage: The wavelength tunability and polarization dependence of gold nanorods can be used to prepare high-capacity information storage devices. Anti counterfeiting: The optical response of gold nanorods in the near-infrared band makes them high-end anti-counterfeiting materials. Surface modification: CTAB micelles are used to modify the surface of citrate capped gold nanoparticles to achieve different surface charges and chemical properties.

2+ Years still working strong!
Color: Black
I’ve been using this charger almost daily since august of 2023 and it still works perfectly charged my iPhone Apple watch and AirPods nightly with cases on the iPhone and AirPods and I have yet to have a problem it’s charged them fully each night! Would definitly recommend if asked about it!

Updating my review, this is a very good product and I was wrong!
Color: White
OK, feeling like a bonehead. Originally unboxed and connected this device to my desktop power supply for a USB powersource. It did not have enough ampirage to charge my watch. I swaped that out before tossing, and found that the supplied power source worked just fine and the device charges both my phone and watch beautifully. So I'm a dope, the product is great, and I am here to correct the review! Given that said, my one gripe is that the adjustiblity of the mount is a bit limited. It's totally functional, but doesn't pivot 360 degrees, and does not telescope like I was expecting. Regardless, it is sleek, a huge space saver, and dejunkified my desktop a great deal. I would defintely buy another one of these. ORIGINAL REVIEW NOW RETRACTED: Annoying. Doesn’t operate as advertised. Watch charger totally inoperable. Mag charger does work. Very disappointing!

It is ok
It is decent. Looks like it would work well. It is a little bulky. I bought this one and another one from a different seller. I returned this one due to the thickness of the arm. It was a little bulky. One thing to be mindful of there is no adjustment for the radius of the arm. Depending on how you position it your phone can be quite far away from the screen, it may not bother you, but for me I wanted them as close as possible

Strong Magnet, Great Price!
Mounted in less than 10 seconds. The magnet is super strong and holds the phone through all the bumps the road throws at it. The two thumb screws make for fast angle adjustment. The mount location puts the phone in the perfect spot for viewing without obstructing the view of the road. This phone holder is built well beyond its price point! I will be buying a second one for the wife's Tesla.
