Learning the diffusion of nanoparticles in liquid phase TEM via physics-informed generative AI

Poseidon AX Publication Alert in Nature Communications on Material Science

Tuesday Publication Post! 📖 Understanding how nanoparticles move in complex liquid environments is key to uncovering the molecular-level forces that drive assembly, reactivity, and transport. Using liquid-phase TEM with the #PoseidonAX holder, authors Zain Shabeeb, Naisargi Goyal, Pagnaa Attah Nantogmah and Vida Jamali directly visualized nanoparticle dynamics in their native environment!

To interpret these trajectories, the authors from #GeorgiaTech introduced LEONARDO, a deep generative model that combines a physics-informed loss function with an attention-based transformer architecture. This allows the model to learn the stochastic motion of nanoparticles even when no closed-form Langevin-style equation exists.

What can LEONARDO do?

💧 Reconstructs nanoparticle motion consistent with LPTEM observations
📈 Captures statistical signatures of heterogeneous, viscoelastic, and environmentally responsive liquid cell conditions
🔬 Provides a new route to connect observed motion to underlying interaction forces
