摘要

在这项工作中,我们介绍了藻酸盐薄膜中合成黑色素的光谱和结构分析。我们提出了一种合成不同浓度黑色素的藻酸盐薄膜的方法。为此,我们用甘油(30% w/w)塑化的 Ca2+ 交联藻酸盐薄膜作为基质,以非溶解状态支持黑色素。我们对藻酸盐-黑色素薄膜的结构和形态特征进行了评估。此外,我们还分析了所获薄膜的结构和形态特征,并分析了它们在电磁波谱的紫外线波段到太赫兹波段的光谱特征。这项研究表明,藻酸盐薄膜是分析和表征非溶解黑色素的可行基质。此外,我们还确定了藻酸盐-黑色素薄膜的分析物理和光学特性与黑色素浓度的关系,并讨论了观察到的变化的相关性。分析表明,黑色素-海藻酸盐薄膜有可能用于进一步检测非溶解黑色素。

Structural analysis and spectroscopic characterization of melanin-alginate films

In this work, we present the spectroscopic and structural analysis of synthetic melanin incorporated within alginate films. We propose a synthesis methodology for alginate films with different concentrations of melanin. For this, Ca2+-crosslinked alginate films plasticized with glycerol (30% w/w) are used as a matrix to support melanin in a non-disolved state. The structural and morphological characteristics of the alginate-melanin films are evaluated. Furthermore, we analyze the structural and morphological characteristics of the obtained films and analyze their spectroscopic characteristics from the ultraviolet to the terahertz bands of the electromagnetic spectrum. This work demonstrates that alginate films are a viable option as a matrix for the analysis and characterization of non-dissolved melanin. Moreover, we determine the dependence of the analyzed physical and optical properties of the alginate-melanin films with respect to the melanin concentration and discuss the relevance of the observed changes. The analysis suggests the potential use of melanin-alginate films for further examination of non-dissolved melanin.
