Quantum dots are tiny particles of a semiconducting material with diameters in the range of 2-10 nanometers (10-50 atoms). They were first discovered in 1980. Quantum dots display unique optical properties, combining high brightness and several distinctive colours. These fetaures make quantum dots particularly suited to be used in sensing and imaging.
Radetec Diagnostics developed a new way to produce highly-fluorescent quantum dots stable in buffers, which can be linked to several biologically-active molecules (e.g. antibodies). Radetec’s quantum dots and other nanoparticles can be purchased on the website: http://www.quantumdoteasyconj.com/
