Tumor Mechanical Remodeling via Bidirectional Calcium Redistribution Enables Deep Photothermal‐Immunotherapy

Advanced Science, EarlyView.
A bidirectional calcium‑redistributing nanomodulator rewires intra‑extracellular calcium homeostasis to remodel tumor mechanical microenvironments. It softens tumor stroma to facilitate deep tissue penetration while stiffening tumor cells, evoking amplified immunogenic cell death and robust CTL infiltration, which achieves potent deep photothermal ...
