摘要：

A marked difference in force-extension curves is observed for carrageenan before and after adding NaI buffer in single-molecule force spectroscopy by means of atomic force microscopy (AFM). The salt-induced helix conformation in carrageenan treated with an 0.1 m NaI solution was unfolded under the external force, and a long plateau about 300 pN high could be observed in the force-extension curves.
