Cation Effect on Slow Release from Alginate Beads: A Fluorescence Study
Kaygusuz, Hakan; Erim, F. Bedia; Pekcan, Önder; Evingür, Gülşen Akin (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 Akin; 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 Akin; Kaygusuz, Hakan; Erim, F. Bedia; Pekcan, Önder (World Scientific, 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 Akin; Pekcan, Önder; von Klitzing, 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 ...
