We propose a simple phenomenological model for describing the conformational dynamics of biopolymers via the nonlinearity-induced buckling and collapse instability. We describe the buckling instability analytically, and then demonstrate its role in the folding dynamics of macromolecules through the three-dimensional numerical simulations of long semiflexible chains.
