Alivisatos is the founding scientist of Quantum Dot Corporation,[25] a company that makes crystalline nanoscale tags that are used in the study of cell behavior.[26] (Quantum Dot is now part of Life Technologies.) He also founded the nanotechnology company Nanosys,[27] and Solexant, a photovoltaic start-up that has since restarted as Siva Power.[28] His research has led to the development of applications in range of industries, including bioimaging (for example, the use of quantum dots for luminescent labeling of biological tissue); display technologies (his quantum dot emissive film is found in the Kindle Fire HDX tablet);[29] and renewable energy (solar applications of quantum dots).
