"Cyanine Dyes: Structure, Uses and Performance begins with evaluation of the potential of 23 novel methine cyanine dyes to inhibit the amyloid fibril formation by insulin, and the limitations in the production and storage of insulin pharmaceutical formulations. Next, the authors describe the spectral properties of a series of monomethine, penthamethine and heptamethine cyanine dyes with an accent on their applicability to non-covalent labeling of biological macromolecules. Additionally, the authors provide an overview of various experimental and theoretical methods for the study of cyanine dyes self-organization, as well as their applications. The closing chapter focuses on exploring the interactions and aggregation behaviour of cyanine dyes within various ionic liquids and deep eutectic solvents-based systems"--.
