title: Efficient magnetic torque transduction in biological environments using tunable nanomechanical resonators.
abstract: Electromagnetic interactions with biological systems promise new possibilities in medical applications and synthetic biology. Creating a controlled action in biological systems requires an efficient transduction of the electromagnetic energy to thermal or mechanical biosignals. In this paper, we present the design and optimization for a nano-scale magnetic torque transducer based on a tunable nanomechanical resonator. Operating in the resonance regime allows the presented system to efficiently absorb a large amount of energy from the source. In addition, systems tuned on well separated resonance frequencies may operate simultaneously without any interference. We describe the theoretical model of the system and show the possibility of achieving the resonance in biological settings for a system with reasonable dimensions.
