Also known as: SPMNPs
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Superparamagnetic iron oxide nanoparticles (SPMNPs) offer a powerful theranostic platform, combining magnetic resonance imaging (MRI)-based diagnostics with therapeutic delivery and hyperthermia.

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.

Superparamagnetic iron oxide nanoparticles are presented as a theranostic platform that combines MRI-based diagnostics with therapeutic delivery and hyperthermia.
Carbohydrate-coated magnetic nanoparticles can exploit altered glycosylation patterns and lectin overexpression on glioma cells to achieve selective cellular targeting.
Combining carbohydrate-functionalized magnetic nanoparticles with external magnetic field guidance provides a dual-action mechanism in which the magnetic field guides nanoparticles across the BBB and concentrates them in the tumor while the carbohydrate coating promotes specific cellular uptake.
