Slug glue--coming to an OR near you
When you get stitches or sutures to sew a wound shut--it is basically a fastener. Fasteners are changing.
I remember when I first got staples. And they pulled them with the same staple puller I had on my desk. Well, why not?
Now, in the 21st century, gels and glues are being used.
Among them--glue made from the stubborn slime of slugs--ever tried to get that off your flagstones?
This is the stuff that allows mollusks to stay on wave-battered rocks or resist hungry birds who would love to pry them off for dinner.
But--adhesives usually will fail when soaked with goo--but sutures and staples also fail. Some sutures are even made to dissolve.
Adhesives are best when cuts are clean and not too deep. They are flexible.
Such gels are a dilute, tangled network of polymers--neither a solid nor a fluid.
In these experiments--slugs are sort of "milked," then returned to the trails where they were found.
Slug wrangler--keep that in mind if you are looking for a job.
Also--Super Glue--I know people who love that for sealing those painful heel cracks.
