Communications Computer Industry Companies Computer Science Data Graphics Hardware Internet and Online Services Mobile Computing Multimedia Networks Operating Systems Programming Software Standards Types of Computers World Wide Web   quantum dot Last modified: Wednesday, May 01, 2002  A nano-scale crystalline structure made from cadmium selenide that absorbs white light and then reemits it a couple of nanoseconds later in a specific color. The quantum dot has been around since the 1980s when scientists were looking into the technology as a way to build nano-scale computing applications where light is used to process information. More recently, however, the technology is being used in medicine. The crystals are one ten-millionth of an inch in size and can be dissolved in water. When illuminated, they act as molecule-sized LEDs and can be used as probes to track antibodies, viruses, proteins, or DNA within the human body.   Mighty Small Dots New quantum phenomena yields some extraordinary bonuses. Quantum Dots Could Form Basis of New Computers Scientists at Purdue University are helping researchers take a quantum leap in computer technology. Scientists Activate Neurons With Quantum Dots By using the molecular-recognition capabilities of living cells, scientists have made selective electrical contacts to neurons.
