In October 2005, Quantum Dot was acquired by Invitrogen. Quantum Dot Corporation has expertise in semiconductor nanocrystal (QDOT) technology and its applications. Quantum Dot uses quantum dot crystals â cadmium selenide nanoparticles â to develop biological detection applications. The company released its initial Qdot product in 2002, garnering an excellent response from the research and drug development community. One result of Quantum Dotâs partnership with Matsushita has been the release of an optical scanner used for gene expression analysis. The scanner functions intandem with Qbeads, polystyrene balls coated with quantum dots that permit âbar codingâ of DNA strands and cellular structures. Quantum Dot develops nanocrystal fluorophores for life science research. The company's products and services employ quantum dot (Qdot) particles, tiny semiconductor crystals that emit light brightly in a range of sharp colors. These nanometer-sized Qdot particles have unique, highly desirable properties that make them a superior detection platform for
