Optical images of one triangular cantilever. a The cantilever is oscillating in air before measurement and the surface is found to be clean and flat. b The cantilever is oscillating in solution with cells adsorbed. c After washing the cantilever with ethanol and rinsing it with PBS most of the absorbed cells desorbed from the cantilever. d The cantilever in water is shown before measurement. e After injection of Au NPs the cantilever is oscillating in cell medium (DMEM-HG medium, Capricorn Scientific, Ebsdorfergrund) supplemented with 10% fetal bovine serum (Sigma Aldrich). f The cantilever is oscillating with absorbed cells and Au NPs in air after measurement without washing
