Episode notes
In this fascinating episode, Dr. Harrington unpacks his cutting-edge research exploring the potential of mistletoe viscin, a natural cellulosic adhesive, for various material and biomedical applications.
Viscin, which consists of cellulose microfibrils encapsulated by a humidity-responsive matrix, possesses an array of properties that render it a promising candidate for diverse applications. Remarkably, its humidity-activated self-adhesive capabilities allow for mechanical drawing into stiff and sticky fibers, which can then be 'welded' into complex 2D and 3D architectures under ambient conditions.
Dr. Harrington's team also found that viscin can be processed into stiff, transparent free-standing films through biaxial stretching in the hydrated state, followed by drying. This process results in cellulose microfibrils aligning along l ...
