Wireless NFC Implant Delivers Chemotherapy Deep Into Tumors With Four-Fold Improved Efficiency

- Researchers from Seoul National University and Korean institutions developed a wireless implantable drug delivery system that uses Near-Field Communication (NFC) technology to deliver anticancer drugs deep into solid tumors without harming healthy tissue. - The Dual-Phoretic Wireless Drug Delivery System (DPw-DDS) achieved over four times greater drug delivery efficiency than standard injection methods and reduced tumor volume by more than 50% within five weeks in vivo experiments. - The system integrates electrophoresis and iontophoresis mechanisms in a compact subcutaneous implant, eliminating the need for external wiring or batteries while supporting various drug types including nanomedicines and mRNA therapeutics. - The platform does not require drug reformulation and can be applied to existing therapeutics, potentially reducing development costs and time while offering applications beyond cancer treatment.
