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 shelf to upgrade my awkward kitchen!
Size: 42 inch 2 Tier
This shelf is exactly what I was looking for for my awkward kitchen in my new house. Don't mind the plywood walls (who knows what the previous owners were thinking 🤣) but anyways, we had this awkward gap between the kitchen counters and the stove, so I got a stainless steel shelf to fill the gap and add some more counterspace, and I found this industrial style pipe shelving, which was the perfect size and height to fit in this gap on the wall and give us more storage/organization space. It's easy to assemble and hang up, and seems very strong and sturdy. It's a little heavy, but lightweight enough to hang easily. Right out of the box, it was disappointing to see some scuffs in the black paint on the piping, especially for the price. Luckily, the biggest scuff is in a pretty inconspicuous space so it's not a big deal. Definitely not worth returning to see if another one wouldn't have any scuffs (especially since many of the other reviews mentioned scuffs too). It's wabi sabi I suppose 😅 Also, not a single extra screw or hardware was included. Not a big deal, but screws are cheap enough to through in one extra just in case one is missing or lost. Overall, mostly happy with the purchase. The wood is solid and the shelf looks nice in my kicthen!

Easy to put together. A little bit too heavy for Sheetrock. I had to use some bigger screws. I love the look with my cabinet.
