Scientists are developing a “smart
glue” – using mussel proteins – that can bond securely underwater and may be
turned on and off with electricity. There is no smart adhesive out there that
can perform underwater. The chemistry that researchers can potentially
incorporate into the adhesive, causing it to reversibly bond and de-bond is
quite new. Such“smart glue” can bind underwater sensors and devices to the
hulls of ships and submarines and help unmanned vehicles dock along rocky
coastlines or in remote locations. The adhesive can also lead to new kinds of
bandages that will stay attached when someone sweats or gets wet, and make it
less painful to remove a dressing. The smart glue may even be used to attach
prosthetic limbs and biometric sensors or seal surgical wounds.
