ROTI^®nanoMETICQuantum dots (QD) are fluorescent nanoparticles of certain semiconducting materials, whose electronic properties closely depend on the size of the particles. The fluorescence wavelength shifts towards red for larger particles, and to blue for the smaller ones. This allows coverage of the complete visible colour spectrum with quantum dots of different sizes and yet the same material. The possibility to control the size of the particles during their manufacturing, allows to precisely adjust their electronic and fluorescent properties. The inorganic nature of quantum dots makes them far more stable than organic fluorescent dyes.

CdTe, hydrophilicThe surface of our cadmium telluride (CdTe) quantum dots is functionalised with COOH groups, which enables optimal dispersion of the particles in aqueous solutions. This also allows easy coupling of the particles to NH₂ groups, which makes the products interesting for a variety of chemical and biochemical applications. The products are delivered as powder in 2 ml vials with septum. Thus, the quantum dots can be dispersed directly in the vial with the chosen solvent.
