  • Cyanine - Wikipedia
    Although the name derives etymologically from terms for shades of blue, the cyanine family covers the electromagnetic spectrum from near IR to UV Chemically, cyanines are a conjugated system between two nitrogen atoms; in each resonance structure, exactly one nitrogen atom is oxidized to an iminium
  • シアニン - Wikipedia
    シアニン (cyanine) は、ポリメチンに属する合成染料である。 シアニン類は 蛍光 染料、特に生物医学イメージングに用いられている。 構造によるが、シアニン類は 赤外 から 紫外 領域のスペクトルをカバーする。
  • Fundamentals in the chemistry of cyanine dyes: A review
    The developments of cyanine dyes synthesis and their applications in photographic and non-photographic multidisciplinary areas are growing continuously, significantly and rapidly Certainly, this will make the present and the future of cyanine dyes chemistry effective, fruitful and very bright
  • シアニン系近赤外蛍光色素 | 東京化成工業株式会社
    シアニン色素は，銀塩写真技術やレーザーに対する感受性を利用して光記録媒体用色素などの機能性色素として利用されています 1) 。 近赤外領域まで吸収を持つものが知られており 2) ，例えばIndocianine Green（ICG）は800 nm付近に最大吸収をもつシアニン色素で，診断薬として使用されています。
  • Cyanine Dyes: Definition, Structure, Types and Uses
    Cyanine dyes are widely used in molecular biology, bioimaging, and diagnostics due to their strong fluorescence, high extinction coefficients, and tunable emission spectra They are employed to label proteins, antibodies, peptides, and nucleotides, enabling real-time visualization of biological processes
  • Cyanine dyes - Lumiprobe
    Cyanine dyes are molecules containing polymethine bridge between two nitrogen atoms with a delocalized charge: Due to their structure, cyanines have outstandingly high extinction coefficients often exceeding 100,000 Lmol-1 cm-1 Different substituents allow to control properties of the chromophore, such as absorbance wavelength, photostability
  • Cyanine Dyes Containing Quinoline Moieties: History, Synthesis, Optical . . .
    The cyanine fluorophores containing quinoline moieties are worthy of attention because of their optical properties such as stability, high molar extinction coefficients, high sensitivity, and low aggregation Therefore, they are useful for biomedicine, as they possess antiseptic and photocleaving properties

    CID 68227 | C29H35IN2 | CID 68227 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety
  • Mechanism of Cyanine5 to Cyanine3 Photoconversion and Its Application . . .
    Cyanine (Cy) dyes are among the most useful organic fluorophores that have found a wide range of applications in single-molecule and super-resolution imaging as well as in other biophysical studies However, recent observations that blueshifted derivatives of Cy dyes are formed via photoconversion have raised concerns as to the potential
  • 4. 2: Cyanine Dyes - Chemistry LibreTexts
    When ultraviolet and visible light is absorbed by the cyanine dyes, the energy is used to cause transitions of the pi electrons from one energy level to another, as sketched in Figure \(\PageIndex{4}\) The longest wavelength transition occurs from the highest-energy occupied level to the lowest-energy unoccupied level
