- Adherent cells avoid polarization gradients on periodically poled LiTaO3 ferroelectricsChristof Christophis
Applied Physical Chemistry, Ruprecht Karls University Heidelberg, Im Neuenheimer Feld 253, Heidelberg, 69120, Germany
Biointerphases 8:26. 2013..If suspension cells, with a lower tendency to establish strong surface contacts are used, no influence of the field gradients is observed. ..
- Quantification of the adhesion strength of fibroblast cells on ethylene glycol terminated self-assembled monolayers by a microfluidic shear force assayChristof Christophis
Applied Physical Chemistry, University of Heidelberg, 69120 Heidelberg, Germany
Phys Chem Chem Phys 12:4498-504. 2010..As the cell spreading area changes with the substrate properties, the adhesion strength per unit area was additionally determined...
- Fibroblast adhesion on unidirectional polymeric nanofilmsChristof Christophis
Applied Physical Chemistry, University of Heidelberg, Germany
Biointerphases 6:158-63. 2011..Based on electron microscopy cross sections we deduce that interactions of cellular filopodia extending into the nanotextured surface are causing the direction depending removal...
- Shear stress regulates adhesion and rolling of CD44+ leukemic and hematopoietic progenitor cells on hyaluronanChristof Christophis
Applied Physical Chemistry, University of Heidelberg, Heidelberg, Germany
Biophys J 101:585-93. 2011..Interestingly, the observations of flow-induced cell rolling are related to those found in the recruitment of leukocytes to inflammatory sites and the mechanisms of stem-cell homing into the bone marrow...
