Randomized trial demonstrates enhanced wet adhesion in tissue adhesives, suggesting a safer surgical alternative.

The aim is to develop a bioadhesive that overcomes limitations of current tissue adhesives in wet environments.
Developed a bioadhesive (PLD) using lipoic acid and a dopamine-functionalized derivative.
Evaluated adhesion strength under wet conditions and biocompatibility after 72 hours.
Assessed swelling ratio and water-activated properties of the bioadhesive.
Achieved water-strengthened underwater adhesion of 50.23 kPa after 180 min immersion.
Demonstrated a swelling ratio of only 2.07% in a physiological environment after 72 hours.
Confirmed cytocompatibility and histocompatibility of the PLD adhesive.
