Mission Statement

As a company NanoAxis holds its products and members to the highest level of excellence, forming the core foundation which enables us to reach our goal to achieve operational and scientific breakthroughs today and for the future. Collaborating with academic and industrial partners, NanoAxis is poised to expand its growing patent portfolio that will allow us to be the leader in semiconductor technology.

What are Quantum Dots (QDs)?

NanoAxis will be producing quantum dots, which are a type of semiconducting nanomaterial. Generally speaking, nanomaterials can be defined as a substance with a dimension of less than 100 nanometers. The image to the right gives a simplistic illustration of a quantum dot.

Commercially available quantum dots are generally made of cadmium selenide/zinc sulfide (CdSe/ZnS) structures, where the CdSe forms the core and the ZnS shell functions as luminescence stabilizer for the QDs, as shown below. The image, below gives you a size perspective of quantum dots relative to other well known objects.

At this size, the materials will exhibit size-dependent properties, which is what NanoAxis will take advantage of with our quantum dots.

Specifically, a quantum dot is a semiconductor whose excitons are confined in all three spatial dimensions. As a result, they have properties that are between those of bulk semiconductors and those of discrete molecules. Quantum dots of the same material, but with different sizes, can emit finely tuned light of different colors. This useful feature, known as luminescence, can be utilized in various applications such as transistors, solar cells, light emitting diodes (LEDs), and diode lasers. Recently, investigation of quantum dots as agents for medical imaging has been pursued by researchers in the industry. More specifically, luminescence and bio-conjugation (biological attachment) to molecules are two key properties of quantum dots that are of great interest. NanoAxis has patent pending technologies that allow our products to perform in this exciting arena.
