Abstract Liquid metal (LM) faces numerous obstacles like spontaneous coalescence, prone oxidizability, and deterioration in photothermal conversion, impeding the potential application as agent. To tackle these issues, several studies have focused on surface engineering strategy. Developing a feasible efficient strategy is crucial to prevent aggregation coalescence of LM, while also ensuring exceptional conversion biosecurity. In order achieve goals this work, biomimetic polydopamine (PDA) armor was chosen encase typical LM (eutectic gallium‐indium‐tin alloy) via self‐polymerization. Characterization results showed that PDA encased nanoparticle exhibited enhanced stability, biosecurity, which could be derived from following factors: (1) The protective shell acted an “armor”, isolating dissolved oxygen water, inhibiting heating‐accelerated oxidation shape morphing. (2) near‐infrared absorption conducive conversion. (3) characteristic advantageous for improving Hence, work presented new reinforce application.

Abstract Despite improvements in cancer survival rates, metastatic and surgery‐resistant cancers, such as pancreatic cancer, remain challenging, with poor prognoses limited treatment options. Enhancing drug bioavailability tumors, while minimizing off‐target effects, is crucial. Metal–organic frameworks (MOFs) have emerged promising delivery vehicles owing to their high loading capacity, biocompatibility, functional tunability. However, the vast chemical diversity of MOFs complicates rational design biocompatible materials.
