Antibiofilm and Anti-Quorum Sensing Potential of Safely-Synthesized Hydrated Zirconium Oxide-Coated Alginate Beads against Some Pathogenic Bacteria
Tamfu, Alfred Ngenge; İspirli Doğaç, Yasemin; Ceylan, özgür; Dediu, Andreea Botezatu; Dinica, Rodica Mihaela (Hindawi Limited, 2023)Water is essential to life, but access to uncontaminated water remains a global challenge. Metal oxides possess particular characteristics required for removing heavy metals, inorganic and organic pollutants from wastewater ... -
Drug delivery systems of CoFe2O4/chitosan and MnFe2O4/chitosan magnetic composites
Yıldırım, Ayşegül; İspirli Doğaç, Yasemin (TAYLOR & FRANCIS INC, 2022)The study consists of three parts. In the first part, synthesis and characterization of core-shell magnetic composite beads based on chitosan and containing two different magnetic nanoparticles were carried out. The beads ... -
MnFe2O4/alginate magnetic beads as platform for cancer drug delivery: an in vitro study of 5-Fluorouracil release
Yıldırım, Ayşegül; İspirli Doğaç, Yasemin (TAYLOR & FRANCIS INC, 2022)MnFe2O4/alginate magnetic beads was prepared, by drop-by-drop process, characterized and evaluated for use in cancer drug (5-Fluorouracil) delivery. In the literature, there are many studies in controlled drug systems where ... -

İspirli Doğaç, Yasemin; Arabacı, Gökmen; Erden, Hanife; Öztürk, Funda (Taylor and Francis Ltd., 2023)In this study, the optimization and characterization of NiFe2O4/Polyhydroxymethyl methacrylate (NF-pHEMA) and Fe3O4/Polyhydroxymethyl methacrylate (M-pHEMA) magnetic nanogel structures were carried out and the usability ... -
Synthesis and Characterization of Chitosan/TiO2 Composite Beads for Improving Stability of Porcine Pancreatic Lipase
Deveci, İlyas; Doğac, Yasemin İspirli; Teke, Mustafa; Mercimek, Bedrettin (Humana Press Inc, 2015)The purpose of the present work is improving stability properties of porcine pancreatic lipase (triacylglycerol lipase, E.C.3.1.1.3) by immobilization on chitosan/TiO2 composite beads. The immobilization parameters were ... -
TiO2 beads and TiO2-chitosan beads for urease immobilization
Doğaç, Yasemin İspirli; Deveci, İlyas; Teke, Mustafa; Mercimek, Bedrettin (Elsevier Science Bv, 2014)The aim of the present study is to synthesize TiO2 beads for urease immobilization. Two different strategies were used to immobilize the urease on TiO2 beads. In the first method (A), urease enzyme was immobilized onto ... -
