Advanced biomaterials in biomedical engineering and drug delivery systems( Book )

7 editions published in 1996 in English and German and held by 145 WorldCat member libraries worldwide

The design of innovative, intelligent functional polymers is providing important new tools for sophisticated diagnosis and treatment. The molecular design and integrated biomedical functions of the new polymers set forth in this volume represent diverse perspectives in the fields of biomaterials and drug delivery systems. An interdisciplinary approach makes available the latest advances in the fields of biomedical and pharmaceutical sciences. The resulting fusion of information will prove valuable to researchers and practitioners concerned with current and future trends in biomedical applications of polymeric materials, and will be especially useful to researchers in academic, government, and industrial organizations

Ultra-Thin Films for Opto-Electronic Applications( Book )

3 editions published in 1999 in English and held by 3 WorldCat member libraries worldwide

Optically active poly(thiophene) with a high stere regularity was synthesized for the first time by using a Rieke zerovalent zinc catalyst. An optically active polymer having more than 93% of Head-Tail linkages was obtained from 3(2(S)-2-methylbutoxy)ethyl)thiophene. Electrical and optical properties of the Head-to-Tail polymer were much superior to those of random-type polymer derived from the same--monomer and the third order non-linearity k3 reached a high value of 10(exp -7) esu

Self Assembled Nano-Photonic Devices Derived from Marine DNA for Opto-Electronic Applications( Book )

2 editions published in 2006 in English and held by 2 WorldCat member libraries worldwide

Optical and photochromic properties of spiropyran-intercalated DNA-surfactant complex films were studied for optical switching. The switching speed was observed as 200-300 ms. They depended on the type of spiropyran as well as the type of surfactant. Spiropyrans containing the oxazine ring and intercalated into DNA showed a very rapid photochromic response. It also showed that photochromic response times became much faster when intensity of the excitation light increased. Various DNA-cationic lipid complexes and their bulk films were also prepared and their physical properties were measured

Developments of Innovative DNA Photonic Devices( Book )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

This research proposal describes preparations of innovative photonic devices based on high purity DNA molecules which are obtained from Salmon roe; DNA molecules have characteristic features of double helical chain structures where aromatic compounds can intercalate into the stacked layers so that various optically active aromatic dyes indicate strong enhancement effects of photonic activities. Thus, various DNA photonic devices have been developed in the world in terms of optical switches, electro-luminescence (EL), lasers and so on. However, these DNA photonic devices adsorb moisture in the air because of hydrophilic character of DNA molecules, leading to decrease photonic activities. Nevertheless, it was reported that a novel hybridization method of the dye-intercalated DNA molecules by means of so-called so-gel process increased stabilities and durability of DNA photonic devices under environmental changes

Stability Improvements of DNA Photonic Devices( )

1 edition published in 2008 in English and held by 1 WorldCat member library worldwide

Recent research results on DNA-lipid complexes have shown various attractive features on E/O or O/E devices, optical memories, switches and sensors by intercalating optical dye into DNA double helix while DNA devices absorbed water under high humidity which led to decreases of optical functions. However, it is possible to improve the stability of DNA devices by encapsulating the DNA-lipid complexes into sol-gel materials or synthetic polymers so that water permeation is prevented by glass or synthetic polymers to stabilize and to keep the optical functions for a long time. This research aims at stability improvements of the DNA photon devices by sealing the DNA devices either by sol-gel glass or polymer blending
