  1. *Interaction between metalloporphyrin gels and L-His gels; A and N denote assembled and no interactions observed in water or air, respectively. Metalloporphyrin gel and L-His gel interactions were tested at least three times.
  2. †Physical properties of the gel assemblies obtained by material tension testing machines. Stress was measured three times for each system. Data are averages along with standard deviations. Stress values for assembly of the metalloporphyrin gel with strained and non-stained L-His gel were same.
