Photosynthetic pigments are essential for photosynthesis whereas photoprotective pigments are necessary for protection against harmful solar radiations including UV-B rays. Among all the photoprotective pigments, melanin is considered to be the key player as it is synthesized in a variety of living organisms. In nature, melanin acts as a photo protectant, chelating agent, antioxidant, charge transport mediator, metal ion balancer and a critical camouflaging colorant. The biosynthesis of melanin involves the enzymes tyrosinase, laccase, and 4-hydroxyphenylpyruvate dioxygenase respectively, that employ different substrates to form a variety of melanin's. The production and extraction of these polymers from plants and animals is a challenging task. Therefore, the focus has shifted to inexpensive sources such as microbes. Also, with the help of recombinant DNA technology, it is possible to increase melanin production. In this review, we have discussed different types of pigment occurring in plants, animals and microbes with special reference to melanin. We have also emphasized on the pathways involved in synthesis of major classes of melanin. Finally, the latest advances towards strain improvement and process development methods along with biological functions, and applications of melanin are also summarized and discussed.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"237 ","pages":"Article 112711"},"PeriodicalIF":4.1,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, textile dyeing using extracts from their roots has been performed for centuries. Many examples of madder dye remain today in museum and conservation collections. Madder is an interesting natural source of dye because it contains up to 68 different colorants. However, many of these dyes are extremely sensitive to hydrolysis, decarboxylation, and degradation from enzymes, extraction chemicals, and processing temperatures. The valuable chemical information embedded in the dye structure may be lost if extraction and analysis are too harsh, resulting in inaccurate color prediction with large color differences. Thus, they are often overlooked as colorants in historical textiles. Over the past decades, traditional extraction techniques have been used to analyze textiles but they are invasive and destructive. As a result, this method is expensive, time-consuming, and in some cases is not suited for the analysis of artwork. But in the last decades, computer techniques have been presented as a powerful tool that enables the prediction of UV–VIS signature spectra and color coordinates with high accuracy using Time-Dependent Density Functional Theory. The aim of this study is to elaborate an efficient color prediction process of madder's root without any chemical degradation of dyes. It will enable the creation of a robust analytical database to identify madder colors in heritage objects. Here, we provide a rapid method to obtain a complete database of predicted UV–VIS spectra and color of anthraquinone derivatives found in Madder. In the context of historical textiles, the detailed color of natural colorants present in the artwork is of paramount importance for conservation and restoration purposes.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"237 ","pages":"Article 112701"},"PeriodicalIF":4.1,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143429808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we introduce a prodrug nano-assembly formed by conjugating methylene blue (MB) and doxorubicin (DOX) through a urea linkage. Notably, the resulting MB-DOX structure incorporates only 1.9 % additional atoms compared to clinical MB and DOX. This formulation effectively masks the cytotoxicity of DOX and eliminates the photosensitivity of MB. Moreover, the amphiphilic nature of MB-DOX facilitates self-assembly into nanostructures without requiring additional carriers, realizing self-delivery. Upon accumulation at the tumor site, light-induced cleavage of the urea bond releases therapeutic MB and DOX, enabling combined photodynamic therapy and chemotherapy with minimal adverse effects. Crucially, our design fulfills self-delivery and reduces the side effects of MB and DOX by simply introducing a urea linkage, eliminating the necessity for carrier materials and bulk protective groups, and holding promise for expediting the clinical translation of prodrugs.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"237 ","pages":"Article 112699"},"PeriodicalIF":4.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143429802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adsorption isotherm indicates that at saturation the TCPP molecules adsorb edge-on with the macrocycle nearly perpendicular parallel to the hBN surface. On the other hand, the atomic force (microscopy AFM) micrographs indicate that a monolayer of flat-on adsorbed TCPP molecules, observed for adsorption from a diluted solution transforms into edge-on adsorbed molecules when more concentrated solutions are used. While for adsorption from a dilute solution, the stationary emission spectra correspond to those reported in literature, they shift 15 nm to longer wavelengths when adsorption occurs from more concentrated solutions suggesting stronger interaction between neighboring chromophores for edge on adsorption. The latter is also suggested by a broadening of the red edge of the fluorescence excitation spectra. Fluorescence decays obtained for the different emission wavelengths can be analyzed globally as quadruple exponential decays linking the four decay times. The non-mono-exponential character of the decay is attributed mainly to energy transfer to non-fluorescent traps. The longest decay time decreases from 5.9 ns for the sample prepared by adsorption from a dilute solution to 4.6 and 4.0 ns from samples prepared from more concentrated solutions. These decay times are about 50 % shorter than the fluorescence decay time of TCPP in ethanol.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"237 ","pages":"Article 112695"},"PeriodicalIF":4.1,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143429809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
