TL;DR: It is shown that the elastic modulus of highly swollen polyelectrolyte films composed of poly(L-lysine) (PLL) and hyaluronic acid (HA) can be changed by more than 1 order of magnitude by addition of gold nanoparticles (AuNPs) in a one-step procedure.
Journal ArticleDOI
Thermoresponsive PEG-based polymer layers: surface characterization with AFM force measurements.
Stefanie Kessel,Stephan Schmidt,Renate Müller,Erik Wischerhoff,André Laschewsky,André Laschewsky,Jean-François Lutz,Katja Uhlig,Andreas Lankenau,Claus Duschl,Andreas Fery +10 more
TL;DR: Investigation of temperature-dependent surface interactions between the polymer coating and a colloidal probe in an aqueous medium by means of atomic force microscopy (AFM) force-distance measurements shows that switching the surface properties provides reproducible adhesion force values.
Journal ArticleDOI
Patterned Thermoresponsive Microgel Coatings for Noninvasive Processing of Adherent Cells
Katja Uhlig,Thomas Wegener,Jian He,Michael Zeiser,Johannes Bookhold,Inna Dewald,Neus Godino,Magnus S. Jaeger,Thomas Hellweg,Andreas Fery,Andreas Fery,Claus Duschl +11 more
TL;DR: A method of gentle, local lift-off of mammalian cells using polymer surfaces, which are reversibly and repeatedly switchable between a cell-attractive and acell-repellent state is developed.
Journal ArticleDOI
The microscopy cell (MicCell), a versatile modular flowthrough system for cell biology, biomaterial research, and nanotechnology
F. U. Gast,Petra S. Dittrich,Petra Schwille,M. Weigel,Michael Mertig,Jörg Opitz,U. Queitsch,Stefan Diez,Bryan Lincoln,Falk Wottawah,Stefan Schinkinger,Jochen Guck,Josef A. Käs,J. Smolinski,Katrin Salchert,Carsten Werner,Claus Duschl,Magnus S. Jäger,Katja Uhlig,Peter Geggier,Steffen Howitz +20 more
TL;DR: A range of applications are presented, including single-molecule analysis by fluorescence correlation spectroscopy (FCS), manipulation of single molecules for nanostructuring by hydrodynamic flow fields or the action of motor proteins, generation of concentration gradients, trapping and stretching of live cells using optical fibers precisely mounted in the PDMS layer.
