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.

When a single one cartridge in a set fails :(
Style: Ink, Style: Ink
This for use in my oldish Epson WF-7840 model, which is an ink guzzler; its decent print quality and large paper format notwithstanding. For work projects and good color on laser & gloss papers, this is the only good ink choice on this model. Well, that is, IF you get all ink cartridges in a set working. Therefore, given its price, it is frustrating that, when a brand new single cartridge (of a set) fails, you can be left with few good choices. Along the years, this has happened to me twice...plus today, just one, of a pricey Epson set, failed. When I've bought from a local store, they have had no problem helping with this issue in the past.. I am sure that Amazon & Epson will make it right also. YET, I do have to send back the whole set, even for a single cartridge replacement, which they DO HAVE AS A SEPARATE item. It is a bit of a drag because I need the printer working now and this magenta ink cartridge is all I needed to work at this time. How about dedicating some of Amazon's awesome IT & AI power to distinguish and better respond to this kind of situation? After all, Artificial Intelligence can sort this kind of thing in just a bit or two.

The EPSON 812 DURABrite Ultra Ink is excellent! It fit perfectly in my printer with no problems at all. The print quality looks sharp, clear, and professional colors come out bright and crisp every time. The ink lasts a long time, so it’s definitely worth the price. I’m very happy with it and will definitely buy again. Great product from Epson!
