Comparison between the materials’ viscoelastic moduli (G′(ω) and G′′(ω)) measured by a conventional bulk-rheology rheometer (open symbols) and the AFM2 method (solid line); (a) 20:1 polydimethylsiloxane (PDMS) gel, using a FORT-TL cantilever with an attached 20 μm silica bead. (b) 5% polyacrylamide gel-like solution, using an ARROW-TL cantilever with an attached 4.7 μm silica bead.
