# Magnetoelectric Nanoparticle Research Lineage **Aliases:** MENP research lineage **Entity class:** Technology, concept, or ecosystem entity **Collection:** [[collections/Neurotech|Neurotech]] **Relationship source:** [[research/Neurotechnology Ecosystem Relationship Graph - 2026-09-10|Neurotechnology Ecosystem Relationship Graph — 2026-09-10]] ## Definition **Magnetoelectric Nanoparticle Research Lineage** is represented in the supplied neurotechnology ecosystem graph through the source-qualified relationships below. This page preserves the graph's direction, predicate, evidence key, and epistemic status without treating technical similarity as ownership, funding, licensing, or organizational identity. <!-- BEGIN NEUROTECH RELATIONSHIP GRAPH 2026-09-10 --> ## Relationships ### Master relationship graph patch — 2026-09-10 **Resolved aliases:** `MENP research lineage` **Collection:** [[collections/Neurotech|Neurotech]] **Relationship source:** [[research/Neurotechnology Ecosystem Relationship Graph - 2026-09-10|Neurotechnology Ecosystem Relationship Graph — 2026-09-10]] **Related source articles:** [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]] · [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]] · [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] #### Outgoing typed edges - **Edge 67 — `funded_under` → [[wiki/DARPA Contract N66001-19-C-4019|DARPA contract N66001-19-C-4019]]** — **VERIFIED**; evidence `MENP_2026`, `DOD_4019`. Contract appears in N3-era nonsurgical BCI work; DoD notice identifies Battelle as prime on same contract number. - **Edge 70 — `includes` → [[wiki/Size-Dependent Intranasal Administration of Magnetoelectric Nanoparticles|intranasal administration study (2021)]]** — **VERIFIED**; evidence `MENP_INTRNASAL`. 30-nm MENs reported to cross BBB; magnetic relocation demonstrated in mouse model. - **Edge 75 — `includes` → [[wiki/In Vivo Wireless Brain Stimulation with Magnetoelectric Nanoparticles|in-vivo wireless brain stimulation study (2021)]]** — **VERIFIED**; evidence `MENP_INVIVO`. Magnetic targeting plus low-intensity field; calcium/c-Fos readouts. - **Edge 79 — `includes` → [[wiki/Controlling Action Potentials with Magnetoelectric Nanoparticles|2024 Brain Stimulation action-potential control study]]** — **VERIFIED**; evidence `MENP_2024`. Excitation and exploratory inhibition via MENPs in rat hippocampal neurons. - **Edge 80 — `includes` → [[wiki/Magnetoelectric Nanoparticle-Based Wireless Brain-Computer Interface|2026 Advanced Science wireless BCI framework]]** — **VERIFIED**; evidence `MENP_2026`. Bidirectional MENP framework; recording remains more theoretical than stimulation. #### Epistemic boundary `VERIFIED`, `VERIFIED_SECONDARY`, `CORPUS`, `STRONG_TECHNICAL_LINEAGE`, `STRONG_TECHNICAL_CONVERGENCE`, `ANALYTIC`, and `UNRESOLVED` are retained as distinct relation states. An edge does not imply ownership, control, funding, licensing, technology transfer, or organizational identity unless its predicate and evidence state that relationship explicitly. <!-- END NEUROTECH RELATIONSHIP GRAPH 2026-09-10 -->
