🦠 A new study reveals how poroelasticity—fluid flow through interstitial spaces—bridges tissue architecture and mechanics, offering new insight into organ behavior and disease progression. 🔗 Journal of Biosciences: bit.ly/3WJWsF1. @yogiboi.bsky.social @felixrico.bsky.social

Happy to share our commentary "Length and time scales bridge poroelasticity and tissue architecture" in collaboration with Ramray Bhat from IISC Bangalore rdcu.be/eMJp1 @yogiboi.bsky.social @dynamo-lab.bsky.social

DyNaMo was at the Fête de la Science this October... Thanks to all the participants ( @ismahene-mes.bsky.social @yfok.bsky.social @yogiboi.bsky.social ). @insermpacacorse.bsky.social #FDSSUD #FDS2025

Demain, la Cellule de Culture Scientifique @univ-amu.fr organise "Recherche dans la ville" et DyNaMo y sera présent. Venez nombreux·ses ! Plus d'informations : www.univ-amu.fr/fr/public/ac...

The curious case of streptavidin–biotin: a non-covalent bond. Single Molecule Force Spectroscopy: “SA-b bond breaks in 1s at equilibrium” SA-b at equilibrium: “Not really, More like 1-10 Days.” (Answer: nobody—we were just pulling way too fast (far from equilibrium)) www.biorxiv.org/content/10.1...

Near equilibrium unbinding of streptavidin/biotin using single molecule acoustic force spectroscopy

The dissociation of the streptavidin-biotin (SA-b) bond has been widely characterized using bulk and single molecule force spectroscopy (SMFS) techniques. However, the dissociation rates ( k off) from...
