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)

Targeting the CD47–SIRPα phagocytic checkpoint in cancer: Biology, translational opportunities, and next‐generation therapeutic strategies

Smart Molecules, EarlyView.
The CD47–SIRPα axis has emerged as a critical innate immune checkpoint that suppresses macrophage‐mediated phagocytosis through a canonical “don't eat me” signal and enables tumor immune evasion. We comprehensively summarize the structural and biological features of CD47 and the molecular mechanisms underlying CD47‐mediated regulation of phagocytosis ...
