CIENCIAS DE LA VIDA

 

“Rapid and Serial Quantification of Adhesion Forces of Yeast and Mammalian Cells”

FluidFM-based single-cell force spectroscopy.

 

"High resolution imaging of the cytoplasmic side of bacteriorhodopsin"

"Three bacteriorhodopsin trimers have been highlighted (white rounded triangles) for clarity."

 

“Example of single-cell force spectroscopy using FluidFM”

In the FluidFM control software, a cell can be selected by placing a cross-hair over it. After this, the cantilever is automatically moved over the cell and spectroscopy starts.
