Book Description
Many Bacteriorhodopsin (BR) mutants were synthesized and their optical absorption properties were measured. Several of the mutants were identified that formed the so-called "Q390 state" at neutral pH, but the ultra-long storage lifetime of this state was not investigated. The double mutant D85N/V49A showed a factor of 50 increase in holographic recording sensitivity compared with the single mutant D85N, and had similar diffraction efficiency. The increased sensitivity of this mutant in the spectral range of laser diodes and its long storage lifetime makes this film a good choice for real-time holographic interferometry systems and optical data storage applications. It was demonstrated that a compact diode laser could be used to record and reconstruct holograms in thick films of the mutant D85N. It was demonstrated that lifetimes of several weeks could be achieved. Since diffusion limits the lifetime, using cross-linked BR can substantially increase it It was also demonstrated that very high data densities could be achieved using shift multiplexing with a speckle wave reference beam. With improved materials (reduced scattering, crosslinked polymer host), a 3 mm thick CD-ROM sized disk of D85N could potentially be used to store hundreds of Gbytes of information.

Book Description
Bionanotechnology is the key integrative technology of the 21st century and aims to use the knowledge, gathered from the natural construction of cellular systems, for the advancement of science and engineering. Investigating the topology and communication processes of cell parts can lead to invention of novel biological devices with exciting applications. Though microscale to nanoscale research offers an excellent space for the development of futuristic technologies, a number of challenges must be overcome. Due to paucity of a dedicated literature on the protein based nanodevices we bring you this monograph that combines collective research works of scientists probing into this fascinating universe of bionanotechnology. The monograph has been written with an aim of surveying engineering design principles of biomolecular nanodevices, prototype nanodevices based on redox proteins, bacteriorhodopsins and natural fibers, and touching upon the future developments in the field.

Book Description
This book provides comprehensive, state-of-the art coverage of photorefractive organic compounds, a class of material with the ability to change their index of refraction upon illumination. The change is both dynamic and reversible. Dynamic because no external processing is required for the index modulation to be revealed, and reversible because the index change can be modified or suppressed by altering the illumination pattern. These properties make photorefractive materials very attractive candidates for many applications such as image restoration, correlation, beam conjugation, non-destructive testing, data storage, imaging through scattering media, holographic imaging and display. The field of photorefractive organic material is also closely related to organic photovoltaic and light emitting diode (OLED), which makes new discoveries in one field applicable to others.
