Tissue modulation with nanoantennas and free-space radio waves

We are developing injectable nanoantennas and radiofrequency (RF) generators to modulate and communicate with the biological tissue with free-space radio waves.

Near-field inductive and capacitive coupling in the radiofrequency (RF) range has been widely used to wirelessly power implanted medical devices. However, the long wavelengths in the frequency range of interest define the length scales of the implant size, usually in the mm to cm range, thereby increasing the damage to the implanted tissue. We are developing a fundamentally new wireless tissue modulation method based on dipole interactions of injectable nanoantennas with free-space, propagating radio waves on the nanoscopic scale. This approach can be generally applied to any application that requires localized delivery of electromagnetic energy via wireless means, such as deep-brain neuromodulation, hyperthermia, and ablation therapies for treating cancers and cardiac arrhythmias. Read our recent Phys. Rev. A and APL Materials papers to learn more.
