Simulation‐Guided Tracer Optimization for Magnetic Particle Spectroscopy: Interplay of Core, Shell and Anisotropy Across Physiological‐Range Viscosities for Single‐ and Dual‐Frequency Excitation

Small, EarlyView.
Single‐frequency magnetic particle spectroscopy (MPS) and frequency‐mixing (FM‐)MPS exhibit complementary viscosity‐dependent signal responses of magnetic nanoparticles (MNP). MPS differentiates predominantly blood‐associated viscosities, whereas FM‐MPS shows pronounced discriminability in cellular and tissue‐like viscosity regimes (sensitivity windows)

Asymptotic r2 Enhancement in Formulation‐Optimized Lipid‐Iron Oxide Nanoparticles for Assessing Glioblastoma Heterogeneity at Ultrahigh‐Field MRI

Small, EarlyView.
Lipid‐coated superparamagnetic iron oxide nanoparticles (LSPIONs) are developed as MRI‐visible lipid nanocarriers for glioblastoma imaging. By tuning nanoparticle size and SPION loading, their transverse relaxivity (r2) can be systematically controlled over one order of magnitude, reaching 390 mm−1 s−1 at 9.4 T.
