Turk, Mustafa; Tamer, Ugur; Alver, Erol; Ciftci, Hakan; Metin, Aysegul U.; Karahan, Siyami (Taylor & Francis Ltd, 2013)The objective of the present study was to fabricate a gold nanoparticle crosslinked chitosan (Ch/AuNPs) composite film simple and to evaluate its use as a carrier matrix for L929-fibroblasts. L929-fibroblasts were seeded ... -
Hydroxyapatite-based nanoparticles as a coating material for the dentine surface: An antibacterial and toxicological effect
Erdem, Umit; Dogan, Mustafa; Metin, Aysegul U.; Baglar, Serdar; Turkoz, Mustafa B.; Turk, Mustafa; Nezir, Saffet (ELSEVIER SCI LTD, 2020)In this study, nano sized hydroxyapatite (nHAp) and Ag(I) doped hydroxyapatite (Ag-nHAp) particles were synthesized by the precipitation method and used as a coating material for remineralization on caries-affected dentine ... -
Immobilization of laccase onto polyethyleneimine grafted chitosan films: Effect of system parameters
Metin, Aysegul U. (Polymer Soc Korea, 2013)Chitosan films were prepared via phase-inversion technique. The polyethyleneimine (PEI) was grafted onto chitosan films after activation with various agents, such as epichlorohydrin, genipin and glutaraldehyde. The PEI ... -
