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.

Beautiful set, highly recommend, works well, great price
Color: Green
This set was gorgeous and worked very well for making Matcha at home. Highly recommend buying the set so you can keep your whisk's shape after rinsing. The holder is beautiful! I have both the holder and the whisk on display in my kitchen next to my matcha and teas. So pretty. Great value.

Great price!
Color: Green
I love it! I waahed it & dried, then used it to make my matcha. I had been using a silicon pastry brush! Lol. (& making a mess) so it was great to have the right tools to make it. Comes with bamboo whisk, ceramic stand, bamboo spoon for consistent measurment, stainless cup size strainer, & bamboo scraper to swipe matcha powder in sifter & scrape lumps from side of bowl or cup. I just made it in the cup today. Simplified the process. I am super pleased.

Poor Whisk Quality
Color: Green
I've had the kit for about a month. This matcha kit would be good for beginners just trying to get into making drinks at home. While I am not as experienced with matcha, I feel you could get a better ensemble to whisk your matcha. Mine is still holding up. I've made around 15 drinks probably? But I can't see the whisk holding on for longer than 3 months. The whisk quality is not very good. The whisk mixes well, but it has a tendency for the bristles to break and bits of bamboo to end up in your drink. The rest of the kit is holding up pretty well. The look of it is cute and minimalistic. Everything is easy to clean, though I think matcha kits are not meant to get very dirty besides coming in contact with matcha and water. If you mix anything else with this kit, I am not sure how well the bamboo will hold up in regards to mold.

Love This Set!
Color: Green
My daughter loves making matcha with this set. It as lasted for her matcha making sessions. The size is perfect to sit on top of the counter top. It's easy to clean, and leaves no after taste of any kind, nothing but great tasting matcha. The whisk makes to mix and get all the matcha powder so non sticks at the bottom or sides. It's a great buy!

Great taste
Flavor Name: Ceremony Matcha-1.06oz
Great quality matcha. It came with a cute little metal spoon. The color was bright green, just the way its supposed to be.
