Dr. Phillip Messersmith, Professor and Chair of Bioengineering, University of California, Berkeley, will present "Water-Triggered Polymerization of a Lipoic Acid for Surgical Adhesion" on Wednesday, October 30th at 9:30 a.m. in MJIS 1001 and via Zoom as part of BME's Distinguished Research Seminar Series.

Abstract: Polymer adhesives play an important role in many medical, consumer and industrial products. Polymers of a-lipoic acid (aLA) have the potential to fulfill the need for versatile and environmentally friendly adhesives, but their performance is plagued by spontaneous depolymerization. In this talk, I will describe a facile method for rapid catalyst-free aLA polymerization induced by contact with water. Application of the monomer to a wet tissue surface afforded rapid solidification of a strong and elastomeric polymer adhesive that is resistant to spontaneous depolymerization. Fetal anomalies are increasingly being addressed with surgical interventions performed in the second or third trimester. Because the fetal membranes that enclose the womb are mechanically fragile and nonhealing, the defect created by the intervention increases the likelihood of preterm premature rupture of the membranes (PPROM), which is associated with increased risk of fetal morbidity and mortality. Adhesive biomaterials are being explored to seal fetal membrane defects, providing mechanical stability to the membranes, reducing amniotic fluid loss, and extending gestation. I will describe our efforts to use our new surgical adhesive to seal fetal membrane defects; preclinical experiments with our aLA surgical glue increased fetal survival from 0% to 100%.
