Abstract

A method, which is called as "nanofishing," enabled us to stretch a single polymer chain with picking it at its two modified termini using atomic force microscope (AFM). A stress-strain curve obtained for a polystyrene oligomer with thiol termini in a good solvent (N,N-dimethylformamide) showed a good agreement with a worm-like chain model, and thus gave microscopic information about entropic elasticity. Solvent effects on the statistical properties of single polymer chains were also investigated. Water and cyclohexane were used as poor solvent and Θ solvents, respectively.
