MIT researchers are at it again. This time, they are using nano-tweezers to pull on molecules and measure the strength of molecular bonds. According to Matthew Lang, an assistant professor of biological and mechanical engineering, "We're trying to understand how nature engineered these molecular linkages to use in different ways." Lead author of the paper is Jorge Ferrer, a recent PhD recipient in biological engineering. Other MIT authors of the paper are Hyungsuk Lee and Benjamin Pelz, graduate students in mechanical engineering. Roger D. Kamm, PhD, the Germeshausen Professor of Mechanical Engineering and Biological Engineering is also an author on this paper. Professor Kamm was my academic advisor when I was a student at MIT.
