“…Quinone dyes have been used for various applications, such as histological staining, rust prevention on metal surfaces, and increasing the conversion efficiency of solar cells, and they have found use as sensors, pH indicators, pigments, inks and dyes for leather, wood, medicine, food and textiles [5,64,65,190,191]. Of these uses, the most popular one is colouration of textiles, whereas their application in bio-inspired systems for energy harvesting and storage is a more recent development.…”

Synthetic dyes are by far the most widely applied colourants in industry. However, environmental and sustainability considerations have led to an increasing efforts to substitute them with safer and more sustainable equivalents. One promising class of alternatives is the natural quinones; these are class of cyclic organic compounds characterized by a saturated (C6) ring that contains two oxygen atoms that are bonded to carbonyls and have sufficient conjugation to show color. Therefore, this study looks at the potential of isolating and applying quinone dye molecules from a sustainable source as a possible replacement for synthetic dyes. It presents an in-depth description of the three main classes of quinoid compounds in terms of their structure, occurrence biogenesis and toxicology. Extraction and purification strategies, as well as analytical methods, are then discussed. Finally, current dyeing applications are summarised. The literature review shows that natural quinone dye compounds are ubiquitous, albeit in moderate quantities, but all have a possibility of enhanced production. They also display better dyeability, stability, brightness and fastness compared to other alternative natural dyes, such as anthocyanins and carotenoids. Furthermore, they are safer for the environment than are many synthetic counterparts. Their extraction, purification and analysis are simple and fast, making them potential substitutes for their synthetic equivalents. Graphic Abstract

“…In the case of the longer exposure time of the oxide with the undiluted dye, a higher absorbance is obtained with an approximate value of 3, this highest point is at 600 nm and belongs to the exposure time of the dye of 4 h, compared to the spectra obtained from the dye. The groups present in the carotenoid molecule bind with the copper oxide film and this generates an alteration that is attributed to the decrease and the fact that the absorbance is shifted to the right, this not only happens with copper compounds, it also happens with TiO 2 that as presented in his work Maciej Zalas [17], also when in contact with the compounds of the carotenoid molecule do not present the same absorption as the dye alone. that there are no changes in terms of the characteristic peaks of the mentioned materials, it is only observed that there is a small edge at the beginning of the x-axis, this is due to the presence of a coloring compound, it is observed that the copper deposit does not contain impurities since the peaks of copper and ITO are very well defined [19].…”

The results obtained from the characterization of a copper deposit on indium doped tin oxide (ITO), inked with natural dye extracted from the Lactarius indigo fungus, for use in Gratzel type solar cells are reported. An electrolyte composed of 0.1 M HNO 3 and 0.5 M CuSO 4 was used, this solution was prepared for copper deposits on the ITO. Cyclic voltammetry was performed at different scan rates to obtain the reduction zone for deposition between potentials of −100 to −500 mV. The dye was obtained from the indigo Lactarius fungus from maceration, once the inked deposits were obtained, characterizations were performed, the initial test was to obtain the Ultraviolet-Visible (UV-visible) of the pure dye, and later the same test was performed on the inked oxide. Electrochemical Impedance Spectroscopy (EIS) was performed on the samples, as well as Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM), to characterize the material properties for its application.

“…To date, only two species of medicinal mushroom dyes have been tested in DSSCs, the Button mushroom Agaricus bisporus [116] and pale-brown Cortinarius sp. [117], both of which are successful in the field. These two species contain significant amounts of electron-absorbing dyes extracted from the fruiting body and act as sensitizers in the DSSC system.…”

In 2015, approximately 195 countries agreed with the United Nations that by 2030, they would work to make the world a better place. There would be synergies in accomplishing the 17 Sustainable Development Goals (SDGs). Synergy using a single sustainable resource is critical to assist developing nations in achieving the SDGs as cost-effectively and efficiently possible. To use fungal dye resources, we proposed a combination of the zero hunger and affordable energy goals. Dyes are widely used in high-tech sectors, including food and energy. Natural dyes are more environment-friendly than synthetic dyes and may have medicinal benefits. Fungi are a natural source of dye that can be substituted for plants. For example, medicinal mushrooms offer a wide range of safe organic dyes that may be produced instantly, inexpensively, and in large quantities. Meanwhile, medicinal mushroom dyes may provide a less expensive choice for photovoltaic (PV) technology due to their non-toxic and environmentally friendly qualities. This agenda thoroughly explains the significance of pigments from medicinal mushrooms in culinary and solar PV applications. If executed effectively, such a large, unwieldy and ambitious agenda may lead the world towards inclusive and sustainable development.
