Efficient removal of acidic dye using low-cost biocomposite beads
Metin, Ayşegül Ülkü; Çiftçi, Hakan; Alver, Erol (2013)The objective of this study is to prepare and characterize chitosan/zeolite biocomposite beads and utilize them as adsorbent for removal of anionic dye, Acid Black 194 (AB194). Characterization studies of biocomposite beads ... -
Electrochemical copper (II) sensor based on chitosan covered gold nanoparticles
Çiftçi, Hakan; Tamer, Uğur; Metin, Ayşegül Ülkü; Alver, Erol; Kizir, Nevin (Kluwer Academic Publishers, 2014)This study outlines a new sensing platform based on glassy carbon electrodes modified by gold nanoparticles (AuNPs) for the determination of heavy metal. A glassy carbon electrode was modified by chitosan stabilized AuNPs. ... -
Fabrication and characterization of gold-nanoparticles/chitosan film: A scaffold for L929-fibroblasts
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 ... -
Non-enzymatic sensing of glucose using a glassy carbon electrode modified with gold nanoparticles coated with polyethyleneimine and 3-aminophenylboronic acid
Çiftçi, Hakan; Alver, Erol; Çelik, Filiz; Metin, Ayşegül Ülkü; Tamer, Uğur (Springer-Verlag Wien, 2016)A non-enzymatic electrochemical method was developed for sensing glucose by using a glassy carbon electrode modified with 3-aminophenylboronic acid (APBA) immobilized on polyethyleneimine (PEI)-coated gold nanoparticles. ... -
One step effective removal of Congo Red in chitosan nanoparticles by encapsulation
Alver, Erol; Bulut, Mehmet; Metin, Ayşegül Ülkü; Çiftçi, Hakan (Elsevier B.V., 2017)Chitosan nanoparticles (CNPs) were prepared with ionotropic gelation between chitosan and tripolyphosphate for the removal of Congo Red. The production of chitosan nanoparticles and the dye removal process was carried out ... -
