Fig. 4: Local mechanical property measurements for p 2.1 scaffold.
From: A hierarchically ordered compacted coil scaffold for tissue regeneration
a SEM images of colloidal probes for local mechanical properties. b Schematic AFM-based force-distance curve (DMT model) and fitting equation. c AFM-based withdrawal force-distance curve at tip positions 6, 8, and 10. d Optical microscopy for the rhombic patterned sample to show the different tip positions. e Theoretical coil density for the rhombic patterned scaffold. f DMT modulus measured by AFM at different tip positions.
