The aggregation-dependent optical properties of eumelanin from human hair are examined. When aggregation is increased, the absorption spectrum extends to lower energy. The absorption spectra of oligomers isolated from black human hair and Sepia officinalis are comparable and are in quantitative agreement with the reported action spectra for photoinduced oxygen consumption and free-radical generation by eumelanin. The agreement between the optical properties of human hair and squid eumelanins suggests the fundamental molecular constituents of the pigments are similar and aggregation-dependent photophysical behavior is a general feature of all eumelanins.
研究了人发中真黑素的聚集依赖性光学性质。当聚集增加时，吸收光谱向低能量延伸。从黑色人发和乌贼墨中分离出的低聚物的吸收光谱具有可比性，并且与报道的真黑素光诱导耗氧和自由基生成的作用光谱在定量上一致。人发和鱿鱼真黑素光学性质之间的一致性表明，这些色素的基本分子成分相似，且聚集依赖性光物理行为是所有真黑素的普遍特征。
