Abstract
Conventional chemotherapy is limited by systemic toxicity, poor tumor penetration, and drug resistance. While mechano-chemo therapy combining mechanical stimulation with chemicals shows promise, existing techniques are in the early stages. A bubble-free acoustofluidic platform using high-frequency surface acoustic waves to apply localized mechanical forces, named ChemoTAP, was developed. This tunable method uses high-frequency surface acoustic wave pulses (~9.67 MHz) to specifically activate mechanosensitive ion channels. This activation triggers calcium flow and cellular stress reactions, which enhance cisplatin-induced apoptosis in cancer cells by 1.78 times. Compared with traditional ultrasound-driven cavitation or sonoporation approaches, ChemoTAP provides accurate, non-invasive mechanical stimulation without the addition of microbubbles. It serves as a precise, non-invasive platform for mechano-chemotherapy, offering new possibilities for overcoming chemotherapy resistance in precision oncology. We believe that with further development, this platform will strengthen its technological foundation, paving the way for its application as a tunable and effective tool in mechano-chemotherapy.
