Key points:

  • SAW enhanced proliferation
  • SAW enhanced migration up to +135%
  • wave type is crucial (vertical substrate deflection)
  • effect conserved for various cell lines

 

>> Funding: Nicolas Färber just has been awarded with a Add-on Fellowship for Interdisciplinary Life Science 2020 of the Joachim-Herz-Stiftung! We congratulate Nico and thank the funders!

Key points:

  • Love waves allow for non-optical sensing of wound-healing-assays
  • Changes in cell adhesion strength influence the effective permittivity
  • Monitoring of culture conditions, like changes in osmolarity, is easily possible
  • Cell detachment kinetics can be measured quantitatively without microscopy

>> Research and Funding: We recently got funding for our collaboration project „Physical and functional interaction mechanisms at cell membranes and vessel walls“

Collaborators:
