Opis

Photonics of biopolymers discusses the processes of energy transformation in photoexcited proteins, nucleic acids, membranes and model systems. The author addresses, among other topics: Light absorption, screening and reabsorption; photometric studies of protein; energy transfer mechanics; fluorescent probes; photomodulation of enzymes, and photoactiviation. Much of the information stems from the author's own wide experience in the field.

Recenzje

From the reviews:

...it is pleasing to see that this book dealing with the interaction of light with bipolymers has a timely appearance...Undoubtedly, the book will be useful for those who want to apply optical spectroscopic techniques to investigate the structural and functional properties of biological macromolecular systems.

--The Physicist

"It is pleasing to see that this book dealing with the interaction of light with biopolymers has a timely appearance. ... After absorption of photons by a biopolymer a number of phenomena are expected to occur ... . Nikolai Vekshin has made a contemplative attempt to address some of these problems. He has presented and analysed ... by using appropriate physical models. ... Undoubtedly, the book will be useful for those who want to apply optical spectroscopic techniques to investigate the ... biological macromolecular systems."
