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

Quantum effects: Due to their extremely small size (below tens of nanometers), GOQDs exhibit significant quantum effects, making their optical properties unique.

Optical performance: The luminescence performance can be optimized by adjusting its size and surface structure.

High surface area: GOQDs have a high surface area, which provides favorable conditions for their applications in catalysis, adsorption, and other fields.

Rich surface functional groups: GOQDs are rich in functional groups on their surface, making them easy to modify and functionalize, thereby expanding their application range.

Stability: GOQDs have a stable structure and are resistant to strong acids, strong bases, and photo corrosion, providing a guarantee for their application in harsh environments.


Application Fields

Biomedical imaging: GOQDs are used as fluorescent probes in biomedical fields such as cell imaging and cancer diagnosis. Its blue light characteristics make imaging clearer and more accurate.

Optoelectronic devices: In the field of optoelectronic devices, GOQDs can be used to prepare high-performance optoelectronic conversion devices and fluorescent displays. Its excellent luminescent performance gives it a unique advantage in the field of display technology.

Sensors: GOQDs can be used as highly sensitive detection materials for detecting environmental pollutants, biomolecules, etc. Its stability and sensitivity make it widely applicable in the field of sensors.

Drug carrier: GOQDs can also serve as drug carriers, utilizing their blue light properties to achieve precise localization and release of drugs, improving therapeutic efficacy and reducing side effects.

Good looking shelves and easy install - skip the included drywall anchors
Color: Black, Number Of Shelves: 2, Size: 22in
I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room. Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project. One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely. The rest of the hardware worked fine and once installed the shelves feel solid and hold items well. Pros - Clean modern look - Easy installation - Feels solid once mounted - Good size for books or decor Cons - The small level included isn’t very accurate — use your own level - One of the metal brackets was slightly bent out of the box but straightened out easily Helpful tip: Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely. Final thoughts: For the price these are nice looking floating shelves that install easily and work well for light storage and decor.

The shelves sag away from the wall overtime
Color: White, Number Of Shelves: 2, Size: 15.7in, Color: White, Number Of Shelves: 2, Size: 15.7in
Although the wood quality and finish of the shelf are clean and well-made, the main issue is that the shelves begin to sag over time while holding around 10 pounds, even though the product listing claims they can support up to 20 pounds. They may perform better on a brick wall, but on drywall you should be cautious. To fix the problem, I had to purchase floating shelf brackets for support, which solved the sagging issue. However, this defeats the purpose of the “floating” aesthetic. Since the shelf is in my bedroom, I can overlook it, but I personally wouldn’t install these in a common area if I wanted a clean floating look.
