Researchers have discovered that a unique adhesive made by the water-dwelling Caulobacter crescentus bacterium can withstand the stress of about 70 N/mm2, the equivalent of 5 tons per square inch, making it the strongest biological adhesive ever measured (Tsang PH et al. Proc Natl Acad Sci U S A. 2006;103:5764-5768). A number of potential medical and engineering applications for such a natural glue can be envisioned, particularly because its effectiveness in wet environments may make it a promising adhesive for procedures such as surgeries.
