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.

Waste of money for me
Size: 3.5 Ounce (Pack of 1)
I brought this product to see if it would help my 1 year old skin because she have a lot of break out and her break out gets badly inflamed and puffy. I try this product and it actually made it worse. It say it help for itching but my child itching increase. It dry up her skin and left like a chalky feel on the skin. I really wish I could get my money back.

Great ingredients - very strong scent
Size: 16 Fl Oz (Pack of 1)
I have really dry skin and frequent eczema so ordered this lotion to try out. I use a standard colloidal oatmeal lotion typically and it's hard to find a good lotion that doesn't have petrolatum. This one uses olive and jojoba oils instead. I ran it through a product safety app and it scored a 93/100 which is REALLY good for an eczema lotion - the only potential problematic ingredient is peppermint leaf which can be an allergen for some folks. It comes with a pump for easy use and I didn't find the lotion too greasy or oily - it seemed to absorb well. My only problem with the lotion is how strong the tea tree oil scent is - I use eczema lotion at bedtime and the smell was so strong, it was keeping me awake. If you're sensitive to tea tree oil, that could be an issue. But it's great for daytime use and has a nice, fresh scent. It's preventing the dryness and cracking on my hands that typically happens with "normal" lotions so the oat kernel flour is doing its job. As long as you don't have an aversion to a strong tea tree oil scent, this is a perfect eczema lotion. I've only ever found a handful of them that don't use petrolatum and I appreciate that this one uses plant oils instead. It works to keep the hands from drying or cracking. The price tag is on point with the other eczema lotion I use with it currently being $21 for 16 oz. Definitely recommend this if you are looking for an ingredient-safe eczema lotion.
