Template‐free tuning of magnetic nanoparticle self‐assemblies in response to external electric and magnetic fields

Responsive Materials, EarlyView.
Electrostatically charged aerosol magnetic nanoparticles enable template‐free self‐assembly of nanochains with tunable length and spacing by adjusting electric‐to‐magnetic field ratios. Lower electric fields favor the self‐assembly of longer and more spatially separated chains, while higher electric fields promote a uniform nanoparticle deposition and ...

Quantitative Imaging of Water Diffusion in Brain Parenchyma at Cellular Resolution Using Stimulated Raman Scattering Microscopy

Small, EarlyView.
A multimodal multiphoton imaging framework enables high‐resolution quantification of water diffusion in brain tissue. By tracking deuterated water via stimulated Raman scattering (SRS) microscopy, this study resolves the microscopic heterogeneity of water diffusion at cellular resolution and determines apparent diffusion coefficients in health and ...

Surface Locomotion of Cell‐Sized Microrobots Subject to Adhesive Heterogeneity

Small, EarlyView.
Chemically powered, cell‐sized microrobots exhibit translational, circular, or spiral motion through a balance among self‐phoretic propulsion, drag, gravity, and heterogeneous surface interactions. Experiments show that microrobot design and substrate conditions regulate both mobility and trajectory type.

Multi‐Scale 3D Printing of Magnetic Polymer Nanocomposites with Controlled Particle Dispersion and Hyperthermic Response

Small, EarlyView.
Dispersion of magnetic nanoflowers in trimethylolpropane ethoxylate triacrylate to generate photocurable nanocomposites is described. Particle dispersion provides processability and target AC‐field stimulated temperature increases. Complex (DLP) printed structures with submicron features are demonstrated, and the potential for stimulated release of ...
