The title is quite a promise, isn’t it? Bruce Lee, associate professor of biomedical engineering at Michigan Tech, is a part of the Office of Naval Research’s (ONR) Young Investigator Program (YIP) and showed how to use pH to make smart underwater adhesives (similar to mussels’ adhesives). He and Saleh Akram Bhuiyan developed a new method using an electrical current to turn off the adhesion of a catechol-containing material.

For extra coolness the adhesive turns red when it’s shut off.  For ultimate coolness, they can turn it back on.

Homework: Md. Saleh Akram Bhuiyan et al, In Situ Deactivation of Catechol-Containing Adhesive Using Electrochemistry, Journal of the American Chemical Society (2020). DOI: 10.1021/jacs.9b11266
