Objectives

  • Polydopamine procedure for nanofibers
  • Myoglobin procedure for nanofibers (repeat)

Procedures

  • Preparing scaffolds
    • Immerse 4 PLA scaffolds (in 5mL test tube) in ~5mL of 10mM, pH 8.5 TRIS polydopamine solution for 1 hour
      • First two scaffolds immersed in solution pH 8.51
      • Second two scaffolds immersed in solution pH 8.59
    • Add 1mL 0.0621mM myoglobin to solution, shake test tube to combine solutions, allow surface functionalization to occur for 5 hours
    • Rinse with deionized water and allow scaffold to dry overnight

Observations

  • Brute force
