Quantum dots, also referred as synthetic atoms, are nanoscale structures exhibiting 3D quantum confinement, i.e. spatial confinement of electron-hole pairs (excitons). As a result of quantum confinement the difference between energy bands increases with decreasing particle size. Therefore custom quantum dots with unique optical and electrical properties can be obtained by tuning their size.
The field of quantum dots is very promising regarding the range of possible applications.
QDs are very versatile materials as they can be functionalized with molecules, such as antibodies or peptides, capped with polymers, or conjugated to carbon nanotubes, to obtain interesting properties for biology, optoelectronics or energy applications.
Quantum dots’ unique optical properties are particularly interesting for in vitro and in vivo imaging applications. In fact, they are perfectly suited for multiphoton microscopy because of their broad absorption and narrow emission spectra, the wavelength of the latter being tunable by size.
More specifically, graphene quantum dots have recently attracted researchers’ interest due to their low toxicity, high stability, photoluminescence and physicochemical properties, giving them potential for biomedical, energy or display applications.
Attonuclei already has nearly a 10 years’ experience in quantum dots and nanomaterials. Therefore, Attonuclei plans to advance “functionalized custom quantum dots” and associated fabrication techniques to the forefront of nanotechnology for tomorrow.

Through collaborative research and development efforts with the universities between different countries and other industrial partners, Attonuclei plans to commercialize high performance “functionalized custom quantum dots”. Other side, Attonuclei currently operates facilities in the France, India, China, Ireland, US and Turkey. Attonuclei plans to advance “Functionalized Custom Quantum Dots” and associated fabrication techniques to the forefront of nanotechnology. Indeed, Attonuclei is a high-tech company whose mission is to research and develop bottom-up quantum dots fabrication techniques for implementation in high value added products. Attonuclei also assists others with product development efforts by providing nanotechnological related services. The company has been conducting joint research and developments with nanotechnological firms to explore possible ways to improve its current portfolio of products and introduce new ones with unique performance properties derived from using “functionalized custom quantum dots” enhanced materials. However, the validation of the products is brought by the demonstration of their efficiency in the industrial application and by obtaining an industrial synthesis process.
Quantum dots are semiconductor nanocrystals with unique properties giving them potential for a broad range of applications.
The most commonly studied quantum dots are made of a cadmium selenide core coated with zinc sulfide, but other materials can be used such as lead selenide, indium phosphide, zinc oxide or silicon for example.
Different methods can be used to manufacture quantum dots such as colloidal synthesis which allows large-scale production.
Due their unique optical properties, quantum dots can be used as fluorescent probes for biomedical imaging.
In the field of energy, incorporation of QDs in solar cells could lead to more efficient light harvesting and energy conversion. Considering optical or energy applications, investigation of quantum dots self-assembly in liquid crystals is interesting in order to obtain specific morphologies.
Moreover nanostructured metamaterials can find application in display technologies or quantum computing as they are capable of highly efficient light transmission.
Apart from semiconductor quantum dots other materials or very promising such as graphene quantum dots. Indeed they exhibit low toxicity, high stability, as well as interesting photoluminescence and physicochemical properties making them suitable for biological, optoelectronics or energy applications. More specifically, GQDs properties such as high surface area and high transparency are particularly promising for energy and display applications.
Attonuclei™ project was founded in 2004 in order to progress the research and development of Custom Quantum Dots technology. Attonuclei has started its independent business life as a “self-funded company”. After coming into operation within the context of the French National Science Research Center and Faculty of Sciences of the University of Nantes (which one of the biggest campus in France) as spin-off and so did begin its nanotechnological race as best institution in the world for the Functional Quantum Dots. Therefore, with a limited number of institutions in the world by starting to perform “bottom-up” productions in the field of quantum dots technology in its laboratory called QuantaDots™. As “innovation” is one of the major elements of its infrastructure and as its acknowledgement by the governmental departments within the institutionalization process is desired, it has been examined by scientific commissions with expert qualities in connection with the French Ministry Of Research (FMOR) and the Attonuclei has succeeded in receiving this title as a result of the examinations. Furthermore, it’s supported by different units associated with the FMOR. It’s an indication of how much the institutions trust the « Road Map » which form the basis for Attonuclei and how durable these are. Finally, Attonuclei S.A.S. was officially created in 2010 and is registered to the CCN in France with the registration N° 520311747 and 1.250.000 euros capital. Attonuclei became established and independently located in Nantes (nearly Faculty of Sciences of the University of Nantes) occupies a nearly 700 square meter building with wet and dry labs and the company is powered by PhD. degree scientists with competencies mainly in quantum dot, nanotechnology and including nano-devices. All labs are fully equipped to conduct quantum dots and nanocrystal synthesis, synthetic organic chemistry, bioconjugation, cell culture, and cell/molecular biological assays. Also, Attonuclei is member of the EMC2 (France) competitive cluster for aerospatial and composite structural elements.
Quantum dots, also known as “synthetic atoms”, are a special class of materials, which are number of applications in different markets. Attonuclei believe that, quantum dots technology is a technology with an ambitious goal, the goal of working at atomic levels to construct new materials with properties tailored to meet specific needs.
