Download or read book Infrared Absorbing Dyes written by Masaru Matsuoka and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: New laser technology has developed a new dye chemistry! Development of the gallium-arsenic semiconductor laser (diode laser) that emits laser light at 780-830 nm has made possible development of new opto-electronic systems including laser optical recording systems, thermal writing display systems, laser printing systems, and so on. Medical applications of lasers in photodynamic therapy for the treatment of cancer were also developed. In such systems, the infrared absorbing dyes OR dyes) are currently used as effective photoreceivers for diode lasers, and will become the key materials in high technology. At the present time the chemistry of IR dyes is the most important and interesting field in dye chemistry. Laser light can be highly monochromatic, very well collimated, coher ent, and, in some cases, extremely powerful. These characteristics make diode lasers a very cheap, convenient, and useful light source for a variety of applications in science and technology. For these purposes, however, IR dyes with special characteristics are required. To develop new IR dyes, it is most important to establish the correlation between the chemical structures of dyes and other characteristics of dyes, such as their absorption spectra. Molecular design of IR dyes predicting the Amax and Emax values by molecular orbital (MO) calculations is now possible even by using a personal computer, and many types of new IR dyes have been demonstrated. Also, new opto-electronic systems using IR dyes as photoreceivers have been reported recently.

Download or read book Primary Photo Processes in Biology and Medicine written by R. V. Bensasson and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently there have been major developments in the experimental techniques available for the study of the primary events following the absorption of ultra-violet and visible radiation by biological systems. These techniques, which include absorption, emission, resonance Raman, electron spin resonance, nuclear magnetic resonance and photoacoustic spectroscopies, can be used to study the fate of transient species with lifetimes ranging from seconds to nanoseconds and extending in some cases, such as laser flash photolysis, to pico 12 15 (10- S)- and even femtoseconds (10- s). In parallel with these developments there has been a dramatic increase in the use of light in medicine via the direct photochemical alteration of endogenous molecules (phototherapy) or via the photoactivation of drugs in the skin or other tissue (photochemotherapy). Thus neonatal hyperbili rubinaemia can be routinely treated by phototherapy and psoriasis is frequently treated by PUVA photochemotherapy. A promising new photo chemotherapy used the phototoxicity of porphyrin drugs activated by red light to destroy solid malignant tumors. While some of the overall qualitative effects of such treatments are known, only recently have we begun to understand the associated molecular mechanisms. The primary molecular processes involve short-lived species. The pur pose of this Advanced Study Institute was to review some newer experi mental techniques for the study of such species, the application of these techniques to biological and medical systems and to examine the value of such information in phototherapeutic situations.

Available in PDF, EPUB and Kindle. Book excerpt: This and its companion Volumes 2 and 3 document the proceed ings of the 4th International Symposium on Surfactants in Solution held in Lund, Sweden, June 27-July 2, 1982. This biennial event was christened as the 4th Symposium as this was a continuation of ear li er conferences dealing with surfactants held in 1976 (Albany) under the title "Micellization, Solubilization, and Microemulsions"; in 1978 (Knoxville) under the title "Solution Chemistry of Surfac tants"; and in 1980 (Potsdam) where it was dubbed as "Solution Be bavior of Surfactants: Theoretical and Applied Aspects:' The Pl02 3 ceedings of all these symposia have been properly chronicled. ', The Lund Symposium was bi lIed as "Surfactants in Solution" as both the aggregation and adsorption aspects of surfactants were covered, and furthermore we were interested in a general title which could be used for future conferences in this series. As these biennial events bave become a weIl recognized forum for bringing together researchers with varied interests in the arena of surfactants, so it is amply vindicated to continue these, and the next meeting is planned for July 9-13, 1984 in Bordeaux, France under the cochair manship of K.L. Mittal and P. Bothorel. The venue for 1986 is still open, although India, inter alia, is a good possibility. Apropos, we would be delighted to entertain suggestions regarding where and when these biennial symposia should be held in the future and you may direct your response to Kk~.
