Two‐Photon Microbubble Printing: Asymmetric Assembly for Continuous Laser Writing (Small 18/2026)

Continuous Laser Writing Two-photon bubble printing integrates nonlinear photochemistry and thermally driven fluid dynamics to achieve material-independent direct laser writing. Femtosecond irradiation generates Ag nucleus and a microbubble whose asymmetric temperature field arises from confined bubble–nucleus contact. This induces Marangoni rear-to-front flow that drives nanoparticle assembly and enables continuous patterning across a wide range of material systems.
