Adhesion strength of 10 kPa poly(ethylene glycol) O,O′,O′′,O′′′-tetra(acetic acid dopamine) amide (PEG-Dop)/NaIO4-based glues as function of the concentration of individual components in the gluing mixture. (A) Dry and wet test conditions (as compared with commercial tissue glues); (B) Molecular weight of poly(ethylene glycol) (PEG) (15% (w/v) PEG-Dop); (C) PEG-Dop concentration (120 mM NaIO4); (D) Hydroxyapatite (Hap) nanoparticle concentration (15% (w/v) PEG-Dop, 120 mM NaIO4); (E) Collagen (Coll) concentration (15% (w/v) PEG-Dop, 120 mM NaIO4); (F) Oxidant concentration (15% (w/v) PEG-Dop). Failure type: I, interfacial; C, cohesive; C + I, mixture of interfacial and cohesive. * p < 0.05, ** p < 0.01, *** p < 0.001.
