摘要
Forced desorption of a semiflexible polymer chain on a solid substrate is theoretically in The pulling force versus displacement is smiled for varying adsorption energy epsilon and persistence length P. It is found that the relationships between pulling force and cantilever displacement show a series of characteristic force spikes at different persistence lengths P. These force spikes become more pronounced but the average magnitude of this force decreases as P grows. Our results are of relevance to the forced desorption of DNA on an attractive wall in single-molecule pulling experiments.
