Recombinant Spider Silk Protein and Delignified Wood Form a Strong Adhesive System

For developing novel fully biological materials, a central question is how we can utilize natural components in combination with biomimetic strategies ways that both allow feasible processing and high performance. Within this development, adhesives play role. Here, have combined two of nature’s excellent silk cellulose, to function as an adhesive system. As initial step processing, wood was delignified. Without lignin, the essential microstructure alignment remain, giving strong scaffold versatile process further. A recombinant spider protein used water-based adhesive. The strength average value 6.7 MPa, maximum up 10 MPa. Samples different strengths showed characteristic features, tear-outs for weaker samples only little tear-out samples. references, bovine serum albumin starch were used. Based on data, propose overall model system highlight multiple variables affect Adhesives, particular, biobased ones, must be developed compatible adherend suitable infiltration so their mechanical properties match adherend. engineering proteins gives unmatched potential designing systems additionally desired such being water-based, biologically produced, renewable.
