“…Recently, the use of indigoids has been widely explored in such devices with a view to the creation of natural and sustainable semiconductors [ 3 – 5 ]. These botanical substances were derived from the plants Indigofera tinctoria and Isatis tintora and have been employed as organic dyes for the textile industry [ 6 ].…”

The purpose of this study was to develop and implement an in silico model of indigoid-based single-electron transistor (SET) nanodevices, which consist of indigoid molecules from natural dye weakly coupled to gold electrodes that function in a Coulomb blockade regime. The electronic properties of the indigoid molecules were investigated using the optimized density-functional theory (DFT) with a continuum model. Higher electron transport characteristics were determined for Tyrian purple, consistent with experimentally derived data. Overall, these results can be used to correctly predict and emphasize the electron transport functions of organic SETs, demonstrating their potential for sustainable nanoelectronics comprising the biodegradable and biocompatible materials.Graphical AbstractIn silico model and gate coupling of indigoid single-electron nano-transistors Electronic supplementary materialThe online version of this article (doi:10.1186/s11671-017-2193-7) contains supplementary material, which is available to authorized users.

“…The predominant fatty acids were palmitic, oleic and arachidonic acids in I. candolleana and I. tinctoria. In addition to similar staining properties of I. tinctoria and I. candolleana [21], fatty acid contents were found to be generally similar. Caprylic acid (8.57%) and cis-10 Heptadecenoic acid (7.12%) in I. tinctoria, cis-11-Eicosenoic acid in I. aucherii (8.24%) and I. buschiana (4.52%), elaidic acid (6.99%) in I. tinctoria subsp.…”

“…Dyeing properties of I. candolleana, I. buschiana and I. tinctoria subsp. corymbosa were examined by using low-technology methods [21]. Brassicaceae collects various phenolic compounds that act as antioxidants in rosette leaves, and these leaves also have anti-inflammatory and anti-allergic activity [22].…”

This study was undertaken to evaluate the health-promoting potentials of Isatis aucherii, Isatis buschiana, Isatis candolleana, Isatis tinctoria subsp. corymbosa and Isatis tinctoria. I. aucherii and I. candolleana are endemic, I. buschiana, I. tinctoria subsp. corymbosa are native in Turkey. While I. tinctoria is a well studied species, there is insufficient information about other endemic and native species. Therefore, this study is focused to reveal the bioactive compounds of poorly studied endemic and native species. In this context, protein, ash, glucosinolates, fatty acids, total phenolic and flavonoid content, and antioxidant activities were determined in leaf extracts. The highest protein and fatty oil contents were observed in I. tinctoria and I. buschiana. Arachidic acid was predominant in I. tinctoria subsp. corymbosa, I. buschiana and I. aucherii, while predominant fatty acids were arachidonic and oleic acids in I. candolleana and I. tinctoria. Glucobrassicin was the main glucosinolate in I. tinctoria, while the others contained gluconapin as the main glucosinolate. Antioxidant activities were correlated with phenolic and flavonoid content, the highest and lowest antioxidant activities were observed in I. buschiana and I. aucherii, respectively. HIGHLIGHTS • I. tinctoria and I. buschiana had the highest protein and fatty oil content. • Gluconapin was the main glucosinolate in Isatis spp., except I. tinctoria. • I. buschiana was found rich in both phenolic and flavonoid compounds. • I. buschiana exhibited the highest antioxidant activity. 2 Comlekcioglu, N.
