Adsorptive removal kinetics of anionic dye onto chitosan films doped with graphene oxide: An in situ fluorescence monitoring
Kahya, Nilay; Bener, Semira; Kaygusuz, Hakan; Evingür, Gülşen Akın; Erim, F. Bedia (Taylor & Francis Inc, 2018)The aqueous adsorption of a fluorescent dye (pyranine) onto crosslinked chitosan-graphene oxide composite films was studied. In situ fluorescence monitoring technique is introduced as easy and fast experimental technique ... -
Antibacterial nano cerium oxide/chitosan/cellulose acetate composite films as potential wound dressing
Kalaycıoglu, Zeynep; Kahya, Nilay; Adimcilar, Veselina; Kaygusuz, Hakan; Torlak, Emrah; Evingür, Gülşen Akın (Pergamon-Elsevier Science Ltd, 2020)Novel chitosan and cellulose acetate polymer composites with nanosized cerium oxide were prepared as potential wound dressing materials. Chitosan and cellulose acetate are natural polymer derivatives with biocompatible ... -
Antimicrobial cerium ion-chitosan crosslinked alginate biopolymer films: A novel and potential wound dressing
Kaygusuz, Hakan; Torlak, Emrah; Evingür, Gülşen Akın; Özen, İlhan; Klitzing, von Regine; Erim, F. Bedia (Elsevier Science Bv, 2017)Wound dressings require good antiseptic properties, mechanical strength and, more trustably, natural material ingredients. Antimicrobial properties of cerium ions and chitosan are known and alginate based wound dressings ... -
Cation Effect on Slow Release from Alginate Beads: A Fluorescence Study
Kaygusuz, Hakan; Erim, F. Bedia; Pekcan, Önder; Evingür, Gülşen Akın (Springer/Plenum Publishers, 2014)In this study, spherical alginate beads containing pyranine (P-y) as a fluorescence probe were prepared by ionotropic gelation of a sodium alginate solution. The steady state fluorescence technique was used to study pyranine ... -
Effect of Calcium Ion Concentration on Small Molecule Desorption from Alginate Beads
Evingür, Gülşen Akın; Kaygusuz, Hakan; Erim, F. Bedia; Pekcan, Önder (Taylor & Francis Inc, 2014)Spherical alginate beads were prepared by ionotropic gelation of sodium alginate through the use of calcium ions. Pyranine (Py) was added to the alginate solution as a small molecule probe for fluorescence studies. Desorption ... -
Gelation of PAAm-PVP composites: A fluorescence study
Evingür, Gülşen Akın; Kaygusuz, Hakan; Erim, F. Bedia; Pekcan, Önder (World Scientific Publ Co Pte Ltd, 2014)Hybrid hydrogels are a new class of composite materials. Polyacrylamide (PAAm) hydrogels are mainly produced by free radical crosslinking copolymerization (FCC) of AAm in the presence of N, N'-methylene bis (acrylamide) ... -
Surfactant and metal ion effects on the mechanical properties of alginate hydrogels
Kaygusuz, Hakan; Evingür, Gülşen Akın; Pekcan, Önder; Klitzing, von Regine; Erim, F. Bedia (Elsevier Science Bv, 2016)This paper addresses the controlled variation of the mechanical properties of alginate gel beads by changing the alginate concentration or by adding different surfactants or cross-linking cations. Alginate beads containing ...
