    Properties of N-Eicosane Silk Fibroin-Chitosan Microcapsules
    (John Wiley and Sons Inc., 2011) Başal, Güldemet; Şirin Deveci, Senem; Yalçın, Dilek; Bayraktar, Oğuz
    PCM microcapsules containing n-eicosane were prepared by complex coacervation of silk fibroin (SF) and chitosan (CHI). Chemical characterization of microcapsules was carried out using Fourier-transform infrared (FT-IR) spectroscopy. Thermal properties and thermal stability of microencapsulated n-eicosane were determined by differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). FTIR spectra confirmed the encapsulation of n-eicosane within the microcapsules. Results from thermal analyses showed that microcapsules consisted of an average of 45.7 wt % n-eicosane, and had a thermal energy storage and release capacity of about 93.04 J/g and 89.68 J/g, respectively.

    Antibacterial Properties of Silk Fibroin/Chitosan Blend Films Loaded With Plant Extract
    (Korean Fiber Society, 2010) Başal, Güldemet; Altıok, Duygu; Bayraktar, Oğuz
    The silk fibroin (SF)/chitosan (CHI) blend films were prepared by dissolving them in formic acid. The morphology of the films was examined by scanning electron microscopy (SEM). The roughness of the membranes was determined by atomic force microscopy (AFM). These films were treated with the extracts of Pistacia terebinthus, Pistacia lentiscus, and Hypericum empetrifolium. Folin-Ciocalteu assay was used to determine the amount of total phenols adsorbed on these blend films. The antibacterial properties of films were tested using disc diffusion and turbidity measurement methods against Escherichia coli and Staphylococcus epidermidis. The release of adsorbed phenolics from the film surface resulted in antibacterial properties. © The Korean Fiber Society and Springer Netherlands 2010.
