Product Overview

 carbon quantum dots CQDs are quasi spherical amorphous carbon nanocrystals composed of sp2 and sp3 cluster carbon structures, surrounded by abundant oxygen-containing functional groups such as hydroxyl, carbonyl, carboxyl, etc. Their main constituent elements are C, H, O, and N. The luminescence mechanism of CQDs can be mainly attributed to these three types: quantum confinement effect, surface state luminescence, and molecular state luminescence. Carbon quantum dots are composed of C=C and C-C bond cores that are prone to π→π * transitions, as well as various organic molecular functional groups distributed on the surface that are prone to n →π * transitions. The structure and composition of carbon quantum dots result in strong absorption of short wavelength light waves in the ultraviolet range (260-320 nm), accompanied by low-intensity absorption of visible light (400-710 nm).

The preparation methods of carbon quantum dots are divided into top-down method and top-down method. The top-down method is to cut large-sized carbon structural materials through physical or chemical methods, mainly including arc discharge, laser ablation, ultrasonic treatment, and chemical oxidation. The bottom-up approach is to aggregate small molecule precursors into large-sized CQDs through chemical reactions, mainly including water/solvothermal, template method, microwave-assisted, and solid-phase methods.

Product Features

 

1. Good water solubility: The surface of carbon quantum dots usually contains abundant hydrophilic groups, such as hydroxyl and carboxyl groups, which enable them to be uniformly dispersed in the aqueous phase, facilitating their applications in biological systems and aqueous environments.

2. Low toxicity and good biocompatibility: Carbon quantum dots have low toxicity to organisms and do not cause significant cell damage or immune reactions.

3. High chemical stability: able to maintain stable structure and performance over a wide range of pH values, temperature conditions, and chemical environments.

4. Easy to functionalize: The abundant functional groups on the surface provide active sites for further chemical modification, which can connect various biomolecules, drug molecules, or other functional groups.

5. Excellent optical performance: It has strong fluorescence emission and high fluorescence quantum yield. Its fluorescence emission wavelength can be adjusted by changing the size, surface state, or doping.


Application Fields

 

1. Biological imaging: Carbon quantum dots have good biocompatibility and low toxicity, and can enter the interior of cells without producing significant cytotoxicity. For example, carbon quantum dots modified with specific antibodies can specifically label antigens on the surface of cancer cells, enabling high-resolution imaging of cancer cells and aiding in early diagnosis of cancer.

2. Biological detection: Due to the influence of metal ions on the fluorescence of carbon quantum dots, they can be used to detect metal ions in the environment or biological samples. For example, when mercury ions are present, the fluorescence of carbon quantum dots will be quenched, thereby achieving sensitive detection of mercury ions. At the same time, it can interact with specific biomolecules (such as proteins, nucleic acids, glucose, etc.) to cause fluorescence changes, which is used for quantitative detection of biomolecules. For example, by binding to aptamers, carbon quantum dots can specifically recognize and detect trace biomarkers in the blood, such as tumor markers.

3. Photocatalytic water splitting for hydrogen production: Composite with semiconductor materials to promote the separation and transfer of photogenerated charges, improving the efficiency of photocatalytic water splitting for hydrogen production. For example, loading carbon quantum dots on the surface of titanium dioxide significantly enhances its photocatalytic activity under visible light and increases hydrogen production.

4. Light emitting devices: Used as a light emitting layer or auxiliary layer in LEDs to improve device performance. For example, carbon quantum dot based LEDs can achieve high brightness and wide color gamut luminescence.

5. Drug carrier: Using its surface functional groups to load drug molecules and achieving controlled drug release through stimulus response (such as pH, temperature, light, etc.). For example, in acidic environments (such as the microenvironment of tumor tissue), carbon quantum dot drug delivery systems release drugs to achieve targeted therapy for tumors.

good
Size: 23.6 Inch, Color: White
I recently added this bathroom shelf, and it’s been a great upgrade for organizing my space. It was easy to install and feels sturdy enough to hold everyday essentials like toiletries, skincare products, and small containers without any issues. The design is simple and clean, which helps it blend in nicely with the rest of the bathroom. It doesn’t take up much space but still provides enough storage to reduce clutter around the sink or shower area. One thing I appreciate is how practical it is for small bathrooms—everything is within reach, and it makes the space feel more organized overall. As long as it’s installed properly, it holds up well and stays secure. The only downside is that heavier items might not be ideal depending on the material, but for regular use, it does the job perfectly. Overall, a functional and affordable solution if you’re looking to add extra storage and keep your bathroom tidy.

Very spacious and beautiful
Size: 23.6 Inch, Color: White, Size: 23.6 Inch, Color: White
A lot of my books fit on here and there’s still more room left if I wanted to buy more books. It’s a simple looking bookshelf but it’s really pretty. It’s also sturdy the only reason I gave it a 4 stars instead of 5 was because it comes with its own plastic screw anchors and they are crap. The shelves were wobbly when we installed them using the plastic screw anchors that came with the packaging. My dad set mine up and luckily he had a bunch of his own so he switched them out with better screw anchors. Once we made that switch it was perfect, there was no wobble or shaking at all. So that’s my only piece of advice. Besides for the screw anchors everything else is perfect

Super easy to install. I use different wall anchors. The anchors like all anchors that come with shelves are not great. The shelves look very clean on the wall.
