Excited to share work out in @jacs.acspublications.org led by Yuxuan and @genlichem.bsky.social on activity-based sensing of acetaldehyde using an inverse electron-demand Diels-Alder reaction, enabling selective detection of two-carbon metabolism! pubs.acs.org/doi/10.1021/...

Copper regulates the evolution of REM sleep and transition of animals from water to land! It all relies on a new “metalloadaptor” function for RAD23B linking Cu uptake to distribution to multiple Cu targets. Tong and Dan co-led this @cp-molcell.bsky.social story www.sciencedirect.com/science/arti...

Happy to share our latest in @jacs.acspublications.org led by Xiao and @genlichem.bsky.social on a new activity-based sensing probe for Cu(I) using a fast alkyne-directed cleavage reaction to discover Mn-sensitized #cuproptosis as a novel type of metal-metal crosstalk! pubs.acs.org/doi/abs/10.1...

Congrats to our grad student Angel on this well-earned award! #chemsky #proudadvisor

Happy to celebrate an early 90th birthday for my dear mentor Harry Gray! #chemsky #graynation @nuchemistry.bsky.social

Activity-based sensors identify cuproplasia and ferroplasia as druggable metal vulnerabilities in cancer! With @ginadenicola.bsky.social and Adam Renslo, we profile cancer cell lines to find those sensitive to Cu or Fe chelation www.pnas.org/doi/10.1073/... www.pnas.org/doi/10.1073/... #chemsky 1/n

First Princeton paper! Activity-based sensing plus narrow Raman signatures enable multiplex copper imaging, revealing crosstalk between high antioxidant response element NRF2 activation and low labile Cu in cancer. Fun project with Wei Min’s lab at Columbia! #chemsky pubs.acs.org/doi/10.1021/...

Inspired by @krishnanyamuna.bsky.social @carolynbertozzi.bsky.social, I’m here too!
