Abstract

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. Physical properties of DN-lipid complexes are greatly dependent on kinds of lipids and chiral lipids from α-amino acids were prepared so that self-assembled structure of DNA molecules was organized. DNA-L-alanine-derived lipid formed a self-assembled film with a liquid crystalline structure, which showed a less water absorption. DNA devices absorbed water under high humidity which led to decreases of optical functions. However, it was possible to encapsulate the DNA-lipid complexes into sol-gel materials so that a water permeation was prevented by glass to stabilize and to keep the optical functions for a long time.
