Synergistic Anti-Cancer Therapy Through Ultrasound-Induced Piezocatalytic Therapy and Tumor Treatment Fields. [PDF]

Adv Sci (Weinh)
A novel, wearable anti‐cancer platform synergistically combines tumor treating fields (TTFs) and piezocatalytic therapy (PCT) via ultrasound‐activated, lead‐free piezocomposites. This strategy efficiently suppresses tumor growth, modulates the immune microenvironment, and demonstrates strong therapeutic synergy in both mouse model of subcutaneous tumor
