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.

Product Features

Uniform size: The size of hydroxylated graphene quantum dots is usually between 1-10 nanometers, and their distribution is relatively uniform, which provides a basis for their application at the nanoscale.

High dispersibility: Due to the abundant hydroxyl functional groups on the surface, hydroxyl functionalized graphene quantum dots exhibit good dispersibility in aqueous solutions and other solvents.

Rich reactive sites: Hydroxyl functional groups provide abundant reactive sites for hydroxylated graphene quantum dots, making them easy to connect or modify with other molecules or materials through chemical reactions.

Excellent optical properties: Hydroxyfossilized graphene quantum dots have efficient fluorescence properties, high fluorescence intensity, and long fluorescence lifetime, which makes them potentially valuable in fields such as biological imaging.

Good stability: Hydroxyfossilized graphene quantum dots exhibit excellent stability in extreme environments such as high temperature, acidity, and alkalinity.


Application Fields

 

Biomedical science:

Biological imaging: The high fluorescence intensity and long lifetime of hydroxylated graphene quantum dots make them a powerful tool for biological imaging, which can be used for cell imaging, tissue imaging, and more.

Drug delivery: The hydroxyl functional groups on its surface can bind with biomolecules to achieve targeted drug delivery, improve therapeutic efficacy, and reduce side effects.

Biosensing: Hydroxyfossilized graphene quantum dots can be used to monitor the interactions of biomolecules and dynamic processes within cells through mechanisms such as fluorescence resonance energy transfer.

Energy sector:

Solar cells: Hydroxygraphene quantum dots are used as one of the key materials for solar cells due to their excellent electronic transport properties and chemical stability.

Best sunscreen
Size: 3 Fl Oz (Pack of 1)
My favorite sunscreen. Been buying if for 2 years and still a great product. It goes on easily and does not make your skin greasy or sweaty. It does not cause breakouts either.

Some white cast
Size: 3 Fl Oz (Pack of 1)
Works well, but definitely leaves white cast. It did better for me than it did for my partner but it was hard to get this to rub in and lot look white on him. Smells decent. I will continue to use.

Your makeup won't get ruined! ❤️
Size: 0.47 Ounce (Pack of 1)
I'm new to skincare and I didn't know we were supposed to wear sunscreen! 😱 Turns out it's arguably the most important step of skincare. First, I like the texture of this sunscreen. It's not greasy, it's velvety and smooth. It feels nice on my skin. I used this for the first time yesterday, and I just want those of you to know who are considering buying this, it applies well against makeup! That was one of my main concerns. I did my skincare with this sunscreen as a final step, then put on my makeup. The sunscreen acted as a primer, honestly, so I skipped primer. When I reapplied the sunscreen hours later, my makeup didn't smear! Instead I had a nice, healthy glow to my skin. I actually think it enhanced my makeup; my makeup seemed to last longer than usual. If you find yourself to be TOO glowy after a while, just apply a bit of translucent powder and your makeup will stretch even longer. Bonus: It fits nicely in your purse! Good for people like me with a million things they insist on carrying around.

Works well when properly applied
Size: 3 Fl Oz (Pack of 1)
I try to always buy the highest SPF that I can find. This one fits the bill. If you apply it thoroughly all over and then reapply every few hours, you shouldn't get burned. I've worn it to the water park numerous times now. I have very sensitive skin, and it's given me no issues. I even put it on my face, just being careful not to get too close to my eye area. Once it absorbs into your skin, it doesn't feel too sticky like some other sunscreens can. Just be aware that it will leave a white residue on your bathing suit if you get it on there, but I've always been able to wash it out and that's a small price to pay for proper sun protection!
