Fig. 3: SMFS results for the interaction of DbaYKY, YY, YKY, KYK, and KKYY with PEG hydrogels.
From: A sandcastle worm-inspired strategy to functionalize wet hydrogels
a A schematic diagram for the SMFS experiments to measure the interaction strength of the adhesion groups with the PEG hydrogels. b Representative F–D curves and rupture force distribution are shown for DbaYKY modified tips. c–f Rupture force distribution and chemical structures for YY (c), YKY (d), KYK (e), and KKYY (f). N values represent the total number of measurements used to plot the histograms.
