25. Olympus Microscopy Resource Center: Physics of Light and Color - Introduction to Light Emitting Diodes
- www.olympusmicro.com
- Introduction to Light Emitting Diodes.
- The developing race among manufacturers of light emitting diodes (LEDs) promises to produce, literally, the most visible and far-reaching transition to date. ...
- The phonograph, tickertape, and mimeograph machines have been replaced by digital technologies in the last few decades, and recently, full-spectrum light emitting diode devices are becoming widespread, and could force incandescent and fluorescent lamps into extinction. ...
- Although light emitting diodes are in operation all around us in videocassette recorders, clock radios, and microwave ovens, for example, their use has been limited mainly to display functions on electronic appliances. ... In fact, even the availability of green-emitting diodes represented a significant developmental step in the technology. ... A breakthrough that enabled fabrication of the first blue LED in the early 1990s, emitting light at the opposite end of the visible light spectrum from red, opened up the possibility to create virtually any color of light. ...
- Light emitting diodes are far more efficient than incandescent bulbs at converting electricity into visible light, they are rugged and compact, and can often last 100,000 hours in use, or about 100 times longer than incandescent bulbs. ...
- As improvements have been made in manufacturing efficiency and toward the ability to produce light emitting diodes with virtually any output color, the primary focus of researchers and industry has become the white light diode. ...
- Details of the fundamental processes underlying the function of light emitting diodes, and the materials utilized in their construction, are presented in the ensuing discussion. ... In contrast, the light emitting diode employs a form of electroluminescence, which results from the electronic excitation of a semiconductor material. ...
- The functional details of the light emitting diode are based on properties common to semiconductor materials, such as silicon, which have variable conduction characteristics. ...
- In its pure form, silicon does not have sufficient charge carriers, or appropriate band gap structure, to be useful in light emitting diode construction, but is widely used to fabricate other semiconductor devices. ...
- Although silicon and germanium are commonly employed in semiconductor fabrication, neither material is suitable for light emitting diode construction because junctions employing these elements produce a significant amount of heat, but only a small quantity of infrared or visible light emission. Photon-emitting diode p-n junctions are typically based on a mixture of Group III and Group V elements, such as gallium arsenide, gallium arsenide phosphide, and gallium phosphide. ... Recently the use of silicon carbide and gallium nitride has permitted blue-emitting diodes to be introduced, and combining several colors in various combinations provides a mechanism to produce white light. ...

26. An {{alpha}}-Particle Emitting Antibody ( 213Bi J591) for Radioimmunotherapy of Prostate Cancer -- McDevitt et al. 60 (21): 6095 -- Cancer Research
- cancerres.aacrjournals.org
- An -Particle Emitting Antibody ( 213Bi J591) for Radioimmunotherapy of Prostate Cancer1 .
- A novel -particle emitting monoclonal antibody construct targeting the external domain of prostate-specific membrane antigen (PSMA) was prepared and evaluated in vitro and in vivo. ...
- The construction of an -particle emitting IgG radiotherapeutic moiety represents a "new class" of potent and specific radiopharmaceuticals used only recently in humans (10 , 11). The radionuclide 213Bi is a short-lived (t1/2 = 46 min) -particle emitting metal-ion generated from the decay of Ac-225. ...
- At the low specific activities represented by the last group, there is essentially no specific binding of the -particle emitting J591 to the targets. ...
- -Particle emitting radiolabeled antibody constructs have been proposed as potent, selective agents to kill single cells (30 , 31). We have shown this in vitro and in humans using an -particle emitting anti-CD33 mAb for treatment of leukemia (10, 11, 12 , 15 , 16). ... Therefore, we now ask whether an -particle emitting agent would be useful in a model for solid tumors, such as prostate cancer, that form micrometastatic disease in the bone marrow. In this study, we describe for the first time the construction of a prostate-specific, -particle emitting agent capable of: (a) binding and internalizing into target cells; (b) selectively killing both individual cells and 1000-cell spheroid clusters; and (c) prolonging tumor-free survival and reducing PSA in mice bearing prostate cancer xenografts. ...
- This is an advantage of using -particle emitting radionuclides because the particles transfer their energy in a region that is in very close proximity to the target. ...
- Spheroids of this size approximate the micrometastatic disease condition and can serve as a therapeutic test for investigating the potency and specificity of -particle emitting IgG directed against multicellular targets. ...
- The tumor model used in this study was not optimal for examining the efficacy of an -particle emitting radioimmunotherapeutic agent because an -particle has a pathlength of two to four cell diameters. ...
- Cellular internalization of -particle emitting radionuclides insures that the 213Bi particulate decay traverses the cell, enhancing the cytotoxicity relative to surface-bound species. ...
- -Emitting bismuth cyclohexylbenzyl DTPA constructs of recombinant humanized anti-CD33 antibodies: pharmacokinetics, bioactivity, toxicity and chemistry. ...
- Radioimmunotherapy with -emitting radionuclides. ...
- Preparation of emitting bismuth-213 labeled antibody constructs for clinical use. ...

- To do so, use tiny semiconductor lasers or special light-emitting diodes, one each for the three primary colorsred, green, and blueand scan their light onto the retina, mixing the colors to produce the entire palette of human vision. ...
- Gamers could experience a heightened sense of reality that liquid-crystal-display goggles could never provide, because the laser or light-emitting diode system could dynamically refocus to simulate near and distant objects with utter realism. ...
- Enter the edge-emitting LED. Unlike conventional LEDs, which emit light from the surface of the chip, an edge-emitting LED has a sandwich-like physical structure similar to that of an injection-laser diode, but it operates below the lasing threshold. ... We also use multiple inexpensive surface-emitting LEDs, each contributing a portion of the overall power, to achieve high brightness. ...
