Name: Carboxyl Graphene quantum dots

Product Overview

Graphene quantum dots (GQDs) are nanoscale fragments of graphene with unique physical and chemical properties, such as quantum size effects, edge effects, etc. By specific synthesis methods, the size, shape, and luminescent properties of GQDs can be controlled. At present, Xianfeng Nano's available quantum dots are divided into graphene oxide quantum dots, graphene quantum dots, semiconductor quantum dots, etc. Customers can choose according to their experimental needs. The preparation methods of graphene quantum dots on sale are divided into bottom-up and top-down, with different colors of luminescence available, such as green light, blue light, red light, and white light. Meanwhile, graphene quantum dots with different functional groups can be selected, which is also helpful for later modification coupling. In addition, nitrogen doped and boron doped graphene quantum dots can be selected. At present, the applications of graphene quantum dots are mostly focused on fluorescence imaging, nanoadditives, antibacterial, and biotoxicity.


Technical Parameter

 

Form: Light yellow particles

Purity:~80%

Note: The water solubility and fluorescence intensity of the powder sample are slightly lower than those of the corresponding solution. Please consult before purchasing.

 

Product Features

 

Quantum effects: Graphene quantum dots exhibit significant quantum confinement and edge effects due to their extremely small size (usually less than 100 nanometers, and can even reach below 10 nanometers). These effects endow CGQDs with unique optical, electrical, and chemical properties.

Good water solubility: Due to the presence of carboxyl groups on the surface, CGQDs have good water solubility, making them easy to disperse and process in aqueous solutions.

Biocompatibility: Carboxylation modification enhances the biocompatibility of graphene quantum dots, making them more suitable for biomedical applications.

Chemical reactivity: The presence of carboxyl groups endows CGQDs with high chemical reactivity, allowing them to connect or modify with other molecules or materials through chemical reactions.


Application Fields

 

Biological imaging: CGQDs have excellent fluorescence performance and biocompatibility, and are therefore widely used in fields such as cell imaging, biomarkers, and tissue imaging.

Optoelectronic devices: With their unique optical and electrical properties, CGQDs have shown potential application value in optoelectronic devices such as light-emitting diodes (LEDs), solar cells, and other fields.

Sensors: The high sensitivity and rapid response capability of CGQDs make them ideal materials for making biosensors and chemical sensors.

Good product
Size: 2.5", Style: Closed Hooks
Strong magnets that stay on wall once applied. Definitely holds the weight that it says it holds on the product. Good size to hold my halters in my barn. Would buy again and I think the price was a little high for this product, but it was worth the purchase.

Versatile and Sturdy Storage Solution
Size: 2.5" & 4" - 4 Pack, Style: Open Hooks, Size: 2.5" & 4" - 4 Pack, Style: Open Hooks
The GATOR MAGNETICS Open Storage Hook has been a great (pricey) solution for adding hooks that are strong and useful. Its simple yet robust design makes it incredibly versatile for various uses around the house. The hook feels sturdy and durable, capable of holding a surprising amount of weight without bending or warping. Installation is as easy as blinking your eyes; the really strong magnets allow for easy attachment to any magnetic surface, and the hook remains securely in place. I've used it for hanging lights and bags in my office and bedroom, providing a neat and accessible storage solution in any setting. The open design ensures quick access to items without the hassle of removing them from a closed loop, which is a fantastic convenience. The magnet seems to be protected well enough with a rubber surface so that I don't have to worry about damaging my tables that I have attached these hooks. In terms of value for money, this storage hook is pricey but no competition that I've seen with the same level of durability and convenience. I'm impressed by its performance and versatility, making it a must-have for anyone looking to organize their space efficiently. Pros: Sturdy and durable build quality Easy magnetic installation on metal surfaces Versatile usage for multiple items Convenient open design for quick access Doesn't damage surfaces Cons: None that I've encountered so far! (Maybe price?) Overall, I highly recommend the GATOR MAGNETICS Open Storage Hook for its durability, versatility, and exceptional functionality. It's a small investment that brings significant organization and efficiency to any space.

Amazingly strong and versatile
Size: 2.5" & 4" - 4 Pack, Style: Open Hooks
I saw these advertised on Instagram and immediately purchased a 4 pack. I really wanted them to work but after trying them on 4-5 different steel surfaces I couldn't'[t get any of them to stick well or hold anything heavier than a wet towel. Maybe a bad batch? A shame. The company took the time to reach out to me after seeing my first review where the hooks wound stick to metal poles in my studio. I definitely was not expecting them to reach out to address my issues with the hooks I purchased and returned. After trying the new replacement hooks out I now could not be more impressed! They are strong, well made and easy to use. The hooks and the magnetic baskets are phenomenal and I highly recommend them. I did a test with the hooks, which held a 75 lb weight with no issues on the side of a craftsman tool box! It seems that any early product issues are fixed. The customer service is fantastic and they really took the time to address the issues and keep their customers coming back happy. Well done! Gator Magnetics is definitely a class act in my book!
