behavior of Thymol blue analytical ph indicator entrapped into sol gel matrix
Materials Letters, 2006Co-Authors: Farid R Zaggout, Issa M Elnahhal, Abed Elfattah A Qaraman, Naji Al DahoudiAbstract:Abstract The preparation of transparent monolithic silica doping with Thymol blue has been carried out by the acid catalyzed sol–gel reaction of tetraethylorthosilicate in the presence of Thymol blue. The immobilized Thymol blue pH-indicator shows similar behavior as its solution counterpart. The UV/VIS spectra indicate that the Thymol blue retains its structure during the sol–gel reactions in terms of response to pH. Thymol blue can be regarded as uniformly distributed in the sol–gel matrix, and the use of SDS surfactant has positive effects on the immobilized Thymol blue monolithic disk by homogenizing the polymerizing system. This research shows that Thymol blue indicator can be used as solid pH sensor.

Thymol/cyclodextrin inclusion complex nanofibrous webs: Enhanced water solubility, high thermal stability and antioxidant property of Thymol.
Food research international (Ottawa Ont.), 2017Co-Authors: Asli Celebioglu, Zehra Irem Yildiz, Tamer UyarAbstract:The development of novel nanomaterials that provide an efficient encapsulation and protection for the active food additives is one of the main focuses of current research efforts at food application areas. From this point of view, in this study, nanofibrous webs from inclusion complexes (IC) of modified cyclodextrins (hydroxypropyl-β-cyclodextrin (HPβCD), hydroxypropyl-γ-cyclodextrin (HPγCD) and methyl-β-cyclodextrin (MβCD)) and essential oils compound (i.e. Thymol) was produced through electrospinning technique. While pure Thymol has a highly volatile nature, the volatility of Thymol was effectively suppressed by the inclusion complexation and ~88-100% (w/w) of Thymol was preserved in electrospun Thymol/cyclodextrin inclusion complex nanofibers (Thymol/CD-IC NF). The aqueous solubility enhancement for hydrophobic Thymol was demonstrated by phase solubility diagram which also suggested the 1:1M inclusion complexation between Thymol and CD molecules. Besides, Thymol/CD-IC NF displayed quite fast disintegration in water compared to poorly water soluble Thymol. By inclusion complexation, high temperature stability for volatile Thymol was achieved for Thymol/CD-IC NF samples. The loading of Thymol in Thymol/CD-IC NF conferred DPPH radical scavenging ability to these nanofibrous webs. So, the Thymol/CD-IC NF have shown antioxidant activity along with enhanced water solubility and high thermal stability of Thymol. In brief, encapsulation of essential oil compounds such as Thymol in electrospun CD-IC nanofibers can promote its potential application in food and oral-care products by associating the large surface area of nanofibrous webs along with CD inclusion complexation which provides enhanced water solubility and antioxidant property, and high temperature stability for Thymol.
