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:

Feels like expensive moisturizer
Size: 1.7 Fl Oz (Pack of 1)
non sticky sun protection! can use in humid weather, feels like good mositurizer hydrating your skin. No white cast. Used during my DR trip and it protected skin from harsh sun.

One of the better American sunscreens
Size: 1.7 Fl Oz (Pack of 1)
One of the better sunscreens you can get in the U.S. for an affordable price. Neutrogena’s facial sunscreens can be a hit or miss, but this is their better ones. I’m used to using Asian sunscreens that feel like a light moisturizer or serum on the face so I’ve been spoiled. It’s nice to find an American sunscreen that is spf 50+ with no white cast that also feels lightweight, non-greasy, and doesn’t sting my eyes. This sunscreen fits the bill. I used four pumps of product to cover my face to get proper coverage. I could have used a little more tbh. The serum is a very light beige and a bit watery in texture. It blends out invisible as advertised. The finish is shiny and a little greasy looking at first, I’ll admit, but it dries down to a natural finish. I did use a Korean toner pad before applying the sun serum. The end result with the Neutrogena sun serum is a natural finish with a subtle healthy glow in 70 degree weather. It does sting my eyes when I sweat or exercise though. One star off for that. Also it does not pill under makeup.

Great SPF for daily use
Size: 1.7 Fl Oz (Pack of 1)
Wonderful for daily use and for under makeup! I love the feel of this SPF. Leaves a nice hydrated feel and makeup goes on top of it perfectly. I have been more compliant with wearing sunscreen everyday since I purchased this. Give it a try!

This SPF 60 makes for an effective moisturizer.
Size: 1.7 Fl Oz (Pack of 1)
Love this stuff. Definitely moisturizes as it's protecting. Only thing, am unable to put around my eyes, as it stings, so will have to find something else to protect the sensitive eye area from the sun. Love the compact size as well and you only need a one small pump for your face. It goes a long way.

Eyes burn but good for face
Size: 1.7 Fl Oz (Pack of 1)
This sunscreen is really light weight and gives me a glow without being to greasy and heavy. I love this sunscreen but it makes my eyes burn throughout the day
