We employed synchrotron infrared spectromicroscopy to provide new insights into the development of self-assembled fibrillar networks. The noncovalent interactions responsible for the occurrence of transient junction zone in 12HSA arise because of hydroxyl−hydroxyl hydrogen bonding. This may result f...
