Quantum Dots & Upconverting Nanoparticles Provided by Alfa Chemistry Can Improve Medical Technology and Energy Research

Quantum dots (QDs) have raised great attention due to their unique advantages. The combination of graphene and quantum dots is a huge progress for it makes the application of graphene in the biological field possible. Earlier this month, Alfa Chemistry announces the launch of a diversified quantum dots & upconverting nanoparticles for researchers from both scientific and industrial communities. The high quality graphene quantum dots (GQDs) supplied can be broadly used to improve medical technology and energy research.

Belonging to the carbon family, GQDs have outstanding performance owing to their ultra-small size, non-toxicity, biocompatibility, excellent photo stability, tunable fluorescence, and water solubility, and thus captures considerable attention in the energy and biomedical fields.

“In general, GQDs can be used in the manufacturing of many products such as batteries, fluorescent polymers, bio-imaging markers, humidity and pressure sensors, photovoltaic devices, light-emitting diodes, photovoltaic devices and more,” says the Marketing Chief of Alfa Chemistry. “However, the synthesis of GQDs used to be very expensive and low-yielded. Thanks to the more recent research, a new method to synthesize GQDs from coal has been developed, which seems to be promising as it allows the production of high quality material at a larger scale while maintaining at a relatively low cost.”

The graphene and quantum dots offered by Alfa Chemistry are listed below:


With the size of 10-13 nm, the FluoDot provided by Alfa Chemistry has abundant surface COOH groups and can be used for cell imaging, solar cell coating materials, protease detection, bioLEDs and many other applications.


With the size of 35 nm (± 10 nm), the GlowDot provided by Alfa Chemistry has bovine serum albumin, organic dye and natural amino acids as its internal contents, and can be applied in cell imaging, pH sensing, fluorescence, drug delivery, etc.

Quantum Dots

Alfa Chemistry offers different types of quantum dots, including the alloyed quantum dots, cadmium free quantum dots, conjugation kits, core type quantum dots, core-shell type quantum dots, and graphene quantum dots.

Upconverting Nanoparticles

Upconversion nanoparticles are nanomaterials that can convert near-infrared low-energy radiation into visible high-energy radiation through a nonlinear optical process. Alfa Chemistry offers a wide range of up-conversion nanomaterials, including PEG-NH2 modified upconverting nanoparticles, SiO2-NH2 modified upconverting nanoparticles, mesoporous SiO2 coated upconverting nanoparticles, oil dispersible upconverting nanoparticles, silica-coated upconverting nanoparticles and more.

All graphene and related products of Alfa Chemistry have passed the strict quality control system and hence are broadly trusted by consumers worldwide. Visit to learn more details.
