Our latest paper was published in PNAS! Congrats to Molly, Yuxing, and everyone involved!
Congratulations to Molly, Yuxing, and colleagues on our new paper appearing today in PNAS! In collaboration with the Shapiro group, we demonstrate that biocompatible focused ultrasound can be used to activate mechanophores for triggered molecular release under physiological conditions. The trick? Protein nanostructures called gas vesicles that function as acousto-mechanical transducers. We are excited about the possibilities this work enables for translating polymer mechanochemistry for biomedical applications. Congrats to all! Read the paper here. Also check out the Caltech news story here, and a story in Physics World here.

Our latest paper was published in JACS! Congrats to Molly, Skylar, and Yan!
Congrats to Molly and coauthors Skylar and Yan on their latest publication appearing in JACS! We show that mechanical force enables an anomolous dual ring-opening reaction of naphthodipyran to generate an unusual dimerocyanine dye with near-IR absorption. Read the paper here, and check out a Research Highlight in Nature Synthesis here. We even wrote a little poem about it:
Two paths diverge, one old of light and one of force anew.
Though light can open only one ring, force pries open two!
Our latest paper was published in ACS Polymers Au! Congrats to Stella, Ross, and Anna!
Congrats to Stella and coauthors Ross and Anna on their latest publication in ACS Polymers Au!
