Published Workflows
Objective: Demonstrate that magnetomechanical stimulation with magnetic nanodiscs can modulate non-transgenic CNS neurons through intrinsic TRPC channels and enable wireless neuromodulation in vitro and untethered DBS in vivo.
Why it works: The abstract states that magnetic nanodisc torque generated by a weak and slow alternating magnetic field can activate neurons through intrinsic TRPC channels, which are mechanosensitive and widely expressed in the brain.

The abstract indicates that magnetic nanodiscs and a weak, slow alternating magnetic field at 50 mT and 10 Hz are required. It also relies on intrinsic TRPC channels being present in the target neurons.; requires magnetic nanodiscs; requires application of a weak and slow alternating magnetic field (50 mT at 10 Hz)
The abstract does not show subtype-resolved TRPC control or detailed targeting specificity. It also does not establish from the abstract alone how broadly the method generalizes across brain regions or disease settings.; abstract does not specify TRPC subtype specificity; abstract does not provide detailed delivery or targeting constraints for the nanodiscs
