Numerical investigation of acoustic cavitation characteristics of a single gas–vapor bubble in soft tissue under dual-frequency ultrasound

Ultrasonics Sonochemistry
The viscoelastic tissue under dual-frequency ultrasound excitation affects the acoustic cavitation of a single gas–vapor bubble. To investigate the effect of the cavitation dynamics, the Gilmore-Akulichev-Zener (GAZ) model is coupled with the Peng ...

Engineering metal‐organic framework‐based smart porous nanoplatforms for targeted therapy and theranostic applications

Smart Molecules, EarlyView.
MOFs offer high porosity and tunability for biomedical applications, especially in cancer therapy via ROS generation and targeted delivery. Though toxicity, stability, and scalability remain key clinical challenges. Drug loading in MOFs exceeds 60%–70% with controlled release behavior.
