Force-dependent PSD of a single molecule of cellulose. Comparison of the PSD of fluctuations of cantilever tip, when free and with a single cellulose molecule attached, held with forces of 320 pN, 620 pN, and 920 pN (in gray lines from top to bottom, respectively). The lines in black correspond to fits using either a simple harmonic oscillator model for the cantilever (solid), or the RIF model of the biopolymer combined with the cantilever (broken lines as shown in the legend) described by Eqs. 1 and 5.
