    Incorporation of Equisetum Arvense Extract Into Silk Fibroin-Hyaluronic Acid Sponge Matrices for Wound Dressing Applications
    (Elsevier, 2012) Uslu, Mehmet Emin; Erdoğan, İpek; Bayraktar, Oğuz
    Equisetum arvense extract has frequently been investigated for its antioxidant capacity, antimicrobial and antitumor properties. However, one of the challenges in natural compound investi-gations is to maintain the stability of polyphenolic compounds during their storage and applications. For this purpose extracts can be incorporated into different forms of biomaterial. In this research silk fibroin (SF) and hyaluronic acid (HA) was used as sponge matri-ces for wound dressing application.

    Cnt Incorporated Polyacrilonitrile/Polypyrrole Nanofibers as Keratinocytes Scaffold
    (Trans Tech Publications, 2019) İnce Yardımcı, Atike; Aypek, Hande; Öztürk, Özgür; Yılmaz, Selahattin; Özçivici, Engin; Meşe, Gülistan; Selamet, Yusuf
    Polypyrrole (PPy) is an attractive scaffold material for tissue engineering with its non-toxic and electrically conductive properties. There has not been enough information about PPy usage in skin tissue engineering. The aim of this study is to investigate biocompatibility of polyacrilonitrile (PAN)/PPy nanofibrous scaffold for human keratinocytes. PAN/PPy bicomponent nanofibers were prepared by electrospinning, in various PPy concentrations and with carbon nanotube (CNT) incorporation. The average diameter of electrospun nanofibers decreased with increasing PPy concentration. Further, agglomerated CNTs caused beads and disordered parts on the surface of nanofibers. Biocompatibility of these PAN/PPy and PAN/PPy/CNT scaffolds were analyzed in vitro. Both scaffolds provided adhesion and proliferation of keratinocytes. Nanofiber diameter did not significantly influence the morphology of cells. However, with increasing number of cells, cells stayed among nanofibers and this affected their shape and size. In this study, we demonstrated that PAN/PPy and PAN/PPy/CNT scaffolds enabled the growth of keratinocytes, showing their biocompatibility.
