“…In fact, this type of lamp has an accelerated artificial aging effect and mimics that of real conditions of exposure of sunlight. A similar study was developed by Guesmi and Clementi in order to assess the durability of the fluorescence finish of natural dyed textile fiber following exposures of different durations to Xenon lamp [26,30]. Experimental results (Figure 7) clearly shows that fluorescence emission intensity has decreased by exposing wool fiber samples to artificial UV-irradiations for different time intervals and may be attributed to the fact that flavone-3-ols (quercetin) and flavones-5-ols (Luteolin) are photolytically unstable due to a greater triplet state population or a higher reactivity with singlet oxygen [31,32].…”

“…Recently several efforts were made to study fluorescence property of synthetic and natural fibers dyed with natural dyes and encouraging results were observed [14,26]. In view of these facts current study was undertaken to (i) characterize the fluorescence property of woolen yarn dyed with Acacia nilotica natural fluorescent dye, (ii) investigate the durability of fluorescence finish, (iii) investigate the fluorescence fading rate of dyed fiber under influence of UV radiations, (iv) investigate the adsorption behavior of dye on wool fiber, and (v) assess the effects of metal salts on fluorescence property of dyed fiber.…”

The present study is aimed to exploit the intrinsic fluorescence emission properties of polyphenols of Acacia nilotica natural dye on natural protein fiber wool. Fluorescence measurements were done before and after dyeing experiments. Owing to these phytoconstituents dyed wool samples illustrate interesting fluorescence property with highest values recorded at 445 nm. Durability of fluorescence finish on exposure to ultraviolet radiations and upon washing has been studied and it was proven that dyed wool samples retain interesting fluorescence properties. Rate of fluorescence fading on exposure to UV radiations follows first order kinetics with decay constant of 9.84×10 -6 s -1 . Results showed adsorption isotherms are best explained by Langmuir type with high regression coefficient value (R 2 =0.998) and dyed wool fibers have an obvious fluorescent effect in the spectral range 400-470 nm. The effects of different metallic mordants on the fluorescence property of dyed wool have been assessed in order to increase fluorescence finish. Wool-mordant-dye interactions were studied by Fourier transform infrared (FT-IR) spectroscopy.

“…Recently discovered properties of natural dyes such as insect repellent [1], deodorizing [2], flame retardant [3], UV protection [4], fluorescence [5,6], and antimicrobial activity [7][8][9], besides being biocompatible, biodegradable, renewable, and nontoxic have revolutionized all industrial sectors especially textile industry for producing more appealing and highly functional value-added textiles [10,11]. This is a result of ecological concerns related with the use of 118 of the azo and benzidine synthetic dyes with 24 carcinogenic aromatic amines as their primary photolytic degradation products, which have motivated researchers all over the globe to explore new eco-friendly substitutes for minimizing their negative environmental impacts [12].…”

“…The proof of concept, based on fluorescence decay, proposes the possibility of using this noninvasive technique to study the evolution of betalains in foods [74,75]. The addition of betaxanthins as a dye to transform dim objects into fluorescent is also possible, as has been demonstrated for wool [76]. Indicaxanthin was used to transform white fabrics into yellow ones by adding the characteristic fluorescence of betaxanthins.…”

The discovery of visible fluorescence in the plant pigments betalains revealed the existence of fluorescent patterns in flowers of plants of the order Caryophyllales, where betalains substitute anthocyanins. The serendipitous initial discovery led to a systemized characterization of the role of different substructures on the photophysical phenomenon. Strong fluorescence is general to all members of the family of betaxanthins linked to the structural property that the betalamic acid moiety is connected to an amine group. This property has led to bioinspired tailor-made probes and to the development of novel biotechnological applications in screening techniques or microscopy labeling. Here, we comprehensively review the photophysics, photochemistry, and photobiology of betalain fluorescence and describe all current applications. BetalainsBetalains are nitrogenous plant pigments that are characteristic for plants belonging to the order Caryophyllales. These pigments are divided into the yellow betaxanthins and the violet betacyanins [1]. The presence of both types of pigments is required for the orange and red colors that coexist in nature with the pure yellow and violet colors. Betalains substitute anthocyanins and play their roles in the colored tissues of most plant families of the Caryophyllales. Both families of pigments are watersoluble and mutually exclusive [2,3]. Numerous studies were performed on the color properties of betalains since they were described as a novel family of pigments, different to 'nitrogenous anthocyanins' [4,5]. However, it was not until 2005 that their natural fluorescence was discovered [6]. In addition, it was demonstrated that under physiological conditions, light emission was exhibited in the plant tissues that contain them, including flowers [7,8].Among the Caryophyllales plants, red beet roots (Beta vulgaris) and the fruits of cacti belonging to the genus Opuntia are the best known sources of betalains, with betanin and indicaxanthin being, respectively, their main pigments [9,10]. Current research has described the betalain content of novel sources, such as the tubers from Ullucus tuberosus [11] or the betalain-containing berries of Rivina humilis [12]. Also, the multiple shades of quinoa grains (Chenopodium quinoa) have recently been reported to be based on betacyanins and betaxanthins [13]. In addition, betalains have in recent years been shown to have promising bioactive properties. Early investigations revealed a strong free radical scavenging capacity of betalains purified from beet root [14]. Subsequent research revealed the existence of an intrinsic activity, present in all betalains, that is modulated by structural factors [15,16]. Furthermore, studies with different human cancer cell lines have demonstrated the potential of betalains in the chemoprevention of cancer [17,18]. In vivo experiments have shown that very low concentrations of dietary pigments inhibit the formation of tumors in mice [19,20] and extend the lifespan of the model animal Caenorhabditis elegans [21...
