The investigation of DNA-based materials attracts attention of scientists from various Laboratories because this is definitely an emerging area in physics, molecular biology, biotechnology, biosensorics, nanobiotechnology as well as in material science.

The book reviews the state-of-the art in the fundamental studies of liquid-crystalline state of double-stranded DNA molecules appeared as a result of their phase exclusion from polymer-containing water-salt solutions. The results presented in this review demonstrate how the fundamental data obtained when studying the physico-chemical properties of doublestranded DNA liquid-crystalline dispersions can be used as a background for induction of a “liquid”- “rigid” state transition, i.e. for the design of novel types of “rigid” DNA nanoconstructions carrying various “guest” molecules which display unique properties of practical importance.

Abstract
The investigation of DNA-based materials attracts attention of scientists from various Laboratories because this is definitely an emerging area in physics, molecular biology, biotechnology, biosensorics, nanobiotechnology as well as in material science. This book compares two different approaches in the structural DNA nanotechnology, i.e. “hybridization” approach and “liquid-crystalline approach”. The book reviews the state-of-the art in the fundamental studies of liquid-crystalline state of double-stranded DNA molecules appeared as a result of their phase exclusion from polymer-containing water-salt solutions. The results presented in this review demonstrate how the fundamental data obtained when studying the physico-chemical properties of doublestranded DNA liquid-crystalline dispersions can be used as a background for induction of a “liquid”- “rigid” state transition, i.e. for the design of novel types of “rigid” DNA nanoconstructions carrying various “guest” molecules which display unique properties of practical importance.Pubblicazioni consigliate
