abstract = {Polymer adsorption is a fundamental problem in statistical
mechanics that has direct relevance to diversedisciplines
ranging from biological lubrication to stability of
colloidal suspensions. We combine experimentswith computer
simulations to investigate depletion induced adsorption of
semi-flexible polymers onto ahard-wall. Three dimensional
filament configurations of partially adsorbed F-actin
polymers are visualizedwith total internal reflection
fluorescence microscopy. This information is used to
determine the location ofthe adsorption/desorption
transition and extract the statistics of trains, tails and
loops of partially adsorbedfilament configurations. In
contrast to long flexible filaments which primarily desorb
by the formation ofloops, the desorption of stiff,
finite-sized filaments is largely driven by fluctuating
filament tails. Simulationsquantitatively reproduce our
experimental data and allow us to extract universal laws
that explain scalingof the adsorption–desorption
transition with relevant microscopic parameters. Our results
demonstratehow the adhesion strength, filament stiffness,
length, as well as the configurational space accessible
tothe desorbed filament can be used to design the
characteristics of filament adsorption and thus
engineerproperties of composite biopolymeric materials.},
