    摘要: To sequence DNA automatically, DNA marked with near infrared fluorescent dyes are electrophoresed in a plurality of channels through a gel electrophoresis slab wherein the DNA samples are resolved in accordance with the size of DNA fragments in the gel electrophoresis slab into fluorescently marked DNA bands. The separated samples are scanned photoelectrically with a laser diode and a sensor, wherein the laser scans with scanning light at a scanning light frequency within the absorbance spectrum of said fluorescently marked DNA samples and light is sensed at the emission frequency of the marked DNA. The light is modulated from said laser at a predetermined modulation frequency and fluorescent light emitted by said DNA bands at said modulation frequency is detected, whereby background noise from the medium through which the light is transmitted is discriminated against.

    摘要: This invention relates to new carbocyanine dye compositions, pharmaceutical compositions comprising such compositions, methods of detecting via near infrared fluorescent imaging incipient cancer cells and selective destruction of cancer cells identified by administration of such pharmaceutical compositions. A method of detecting and destroying cancer cells includes introducing a gold dye into an organism suspected of having a cancer cell. The gold dye is a carbocyanine dye covalently attached to a gold nanoparticle. A near infrared light is shined on a region suspected of having the cancer cell. Fluorescence from the gold dye is detected. A beam of radio frequency energy is directed at the region to induce hyperthermia in the cancer cell. The carbocyanine dye has the most basic structure of MHI-148 and structures 6 and 22 with a Aun—[CH2(CH2)9CH2—(OCH2CH2)4O]COCH2CH2-phenyl-O group on a cyclohexene ring that imparts activity to the cancer cell binding and destruction processes.

    摘要: A system for stabilizing the arc in a DC arc lamp. An AC signal is superimposed on the DC power source of the lamp to cause small regular fluctuations in the arc. The small fluctuations prevent large fluctuations while the small regular fluctuations may be averaged to obtain a constant average value. The average is taken over 5 to 10 periods of the AC signal to produce a constant average signal with a very small standard deviation.
