Published Workflows
Objective: Enable non-invasive remote magnetogenetic brain stimulation by using theranostic ultrasound to open the BBB and deliver SPIONs plus viral vectors encoding thermoreceptors and GEVIs, while expanding opening volume to improve delivery scope.
Why it works: The workflow is presented as effective because ThUS can transiently open the BBB for non-invasive delivery of magnetogenetic components, and MOVE expands the opening volume so that delivery and expression can cover larger brain regions within a single treatment.

Stages
- 1.ThUS-mediated BBB opening and payload delivery(functional_characterization)
This stage exists to replace invasive, highly focal surgical introduction of magnetogenetic components with a non-invasive delivery route through transient BBB opening.
Selection: Use theranostic ultrasound to transiently open the BBB and deliver SPIONs plus viral vectors encoding thermoreceptors and GEVIs non-invasively.
- 2.MOVE pulse sequence expansion of opening volume(secondary_characterization)
This stage exists to enlarge the volume of BBB opening during one treatment so that gene delivery can be increased and expression can extend across larger brain regions.
Selection: Apply the MOVE pulse sequence to maximize BBB opening volume within a single ThUS treatment.
Steps
- 1.Transiently open the BBB with theranostic ultrasounddelivery platform
Create non-invasive access for delivery of magnetogenetic components to the brain.
BBB opening is required before non-invasive delivery of SPIONs and viral vectors can occur.
- 2.Deliver SPIONs and viral vectors encoding thermoreceptors and GEVIs non-invasivelydelivery-enabling platform
Introduce the components needed for remote magnetogenetic modulation and fluorescence-based monitoring.
Payload delivery follows BBB opening because the opening facilitates non-invasive entry of nanoparticles and viral vectors into the brain.
- 3.Apply the MOVE pulse sequence across multiple targeted focal zonespulse-sequence component
Maximize BBB opening volume within a single ThUS treatment.
After establishing ThUS-enabled delivery, the workflow expands opening volume to improve delivery extent and expression breadth within the same treatment session.
- 4.Assess delivery gain and expression breadth after MOVEintervention being evaluated
Determine whether expanded opening volume improves gene delivery and expression coverage.
Outcome assessment follows MOVE application to test whether the expanded opening strategy produces the intended delivery benefits.
Objective: Engineer and apply magnetic field-based actuation systems for remote control of cellular functions, especially in contexts where deep-tissue non-invasive stimulation is desired.
Why it works: The review frames magnetogenetics around coordinated choice of magnetic fields, magnetic actuators, and cellular targets, because actuation depends on how field configuration and actuator properties interact with the intended biological target.

Stages
- 1.Actuation component and field-configuration analysis(library_design)
The review presents understanding of field approaches, configurations, and actuator physicochemical determinants as the foundation for later biological application examples.
Selection: Identify how magnetic fields can manipulate magnetic actuators and which field configurations and physicochemical parameters influence actuator magnetic properties.
- 2.Biological application examples(functional_characterization)
After introducing physical actuation principles, the review moves to examples showing how those principles are used to control cellular functions.
Selection: Assess magneto-mechanical and magneto-thermal stimulation in biological use cases such as stem cell fate control, neuronal activation, and apoptotic pathway stimulation.
- 3.Critical mechanism and field-readiness assessment(decision_gate)
The review explicitly highlights unresolved mechanisms and obstacles as barriers to adoption.
Selection: Evaluate controversial aspects and insufficiently elucidated mechanisms of action in magnetogenetics constructs and approaches.

The review comparatively analyzes biophysical, genetic, and biological neuromodulation approaches with emphasis on molecular targets and translational potential.
The reviewed neuromodulation methods were assessed based on specificity, safety, reversibility, and mechanistic clarity.
A critical gap in commonly used neuromodulation methods is incomplete mechanistic understanding, and identifying molecular targets may improve therapeutic precision.
Botulinum neurotoxins provide long-lasting yet reversible inhibition through well-characterized molecular pathways but require stereotaxic injections and remain invasive.
Biophysical neuromodulation methods are widely used in clinical practice but often rely on empirical outcomes because their molecular targets are undefined.
Genetic neuromodulation tools offer cell-type precision in experimental systems but face translational barriers related to delivery and safety.
