Journal ArticleDOI
Complex tracer diffusion dynamics in polymer solutions.
Apostolos Vagias,Riccardo Raccis,Kaloian Koynov,Ulrich Jonas,Hans-Jürgen Butt,George Fytas,Peter Košovan,Peter Košovan,Olaf Lenz,Christian Holm +9 more
TL;DR: The tracer dynamics can be used as a sensitive probe of the nature and strength of interactions, which-despite their local character-emphasize the role of chain connectivity.
Journal ArticleDOI
Dynamics in Stimuli-Responsive Poly(N-isopropylacrylamide) Hydrogel Layers As Revealed by Fluorescence Correlation Spectroscopy
Apostolos Vagias,Peter Košovan,Peter Košovan,Kaloian Koynov,Christian Holm,Hans-Jürgen Butt,George Fytas +6 more
TL;DR: In this paper, fluorescence correlation spectroscopy was employed to study the translational mobility of molecular tracers in stimuli-responsive grafted poly(N-isopropylacrylamide) (PNiPAAm) hydrogels, under variable solvency conditions.
Journal ArticleDOI
Diffusion and Permeation of Labeled IgG in Grafted Hydrogels
Apostolos Vagias,K. Sergelen,K. Sergelen,Kaloian Koynov,Peter Košovan,Jakub Dostalek,Ulrich Jonas,Wolfgang Knoll,George Fytas +8 more
TL;DR: This work studies the diffusion of fluorophore-labeled protein immunoglobulin G in micrometer thick, grafted hydrogel layers based on thermoresponsive poly(N-isopropylacrylamide) (pNiPAAm) by fluorescence correlation spectroscopy (FCS).
Journal ArticleDOI
Preparation of Monodisperse Giant Unilamellar Anchored Vesicles Using Micropatterned Hydrogel Substrates.
Jennifer Schultze,Apostolos Vagias,Lijun Ye,Ephraim Prantl,Valentina M. Breising,Andreas Best,Kaloian Koynov,Carlos M. Marques,Hans-Juergen Butt +8 more
TL;DR: A gel-assisted formation method is introduced, able to produce arrays of giant unilamellar anchored vesicles (GUAVs) with a predetermined narrow size distribution, based on micropatterned gel substrates of cross-linked poly(N-isopropylacrylamide).
Journal ArticleDOI
Molecular Tracer Diffusion in Nondilute Polymer Solutions: Universal Master Curve and Glass Transition Effects
Apostolos Vagias,Jennifer Schultze,Mikheil Doroshenko,Kaloian Koynov,Hans-Jürgen Butt,Mario Gauthier,George Fytas,Dimitris Vlassopoulos +7 more
TL;DR: In this article, the diffusion dynamics of a molecular probe in solutions of polystyrene and polybutadiene with different molar masses (Mw) and molecular architectures (stars, combs) over a broad concentration range (c) were investigated.
