Analysis of the LP-capped and MPLE samples. A FTIR spectrums of MPLE samples and their monomeric compounds. B TGA, (C) in vitro degradation rate up to 56 days, (D) swelling behaviour, (E) tensile stress strain curves, (F-a) toughness of PEGDA, LP-capped and MPLE gel samples and (F-b) enlarged view of toughness of the gel samples. G Properties of the MPLE gels in uniform cylindrical shapes with color changes depending on the amounts of PEGDA in the MPLE gel; H the recovery of the MPLE gel (1:0.3) under compression mode (Initial state, 80% compression state and compression released); for PEGDA, LP-capped and MPLE gels, (I) Compressive stress-strain curves up to 80% strain; J their ultimate compressive strength and (K) Texture profile analysis (TPA), where (a) hardness and (b) adhesiveness values
