Responsive Mn‐Ferrite Nanoparticles for Multicolor Magnetic Particle Imaging, Sensing, and Reactive Oxygen Species Degradation

Advanced Sensor Research, EarlyView.
Magnetic particle spectroscopy and imaging represent promising tools, particularly when combined with manganese‐ferrite nanoparticles as versatile theranostic agents. Adjusting the manganese content allows for simultaneous multi‐color tracer detection and reactive oxygen species sensing via magnetic particle spectroscopy and imaging, creating new ...

NaBC1 Boron Transporter Enables Myoblast Response to Substrate Rigidity via Fibronectin‐Binding Integrins

Advanced Science, EarlyView.
Cells transduce the rigidity of the environment into biochemical cues through mechanotransductive cascades that modulate cell behavior. Here, a novel role for the boron transporter NaBC1 is identified as a mechanotransducer involved in regulating cell behavior via specific crosstalk with fibronectin‐binding integrins.

Ultralow‐Dimensionality Reduction for Identifying Critical Transitions by Spatial‐Temporal PCA

Advanced Science, EarlyView.
The proposed spatial‐temporal principal component analysis (stPCA) method analytically reduces high‐dimensional time‐series data to a single latent variable by transforming spatial information into temporal dynamics. By preserving the temporal properties of the original data, stPCA effectively identifies critical transitions and tipping points.

Quantitative Super‐Resolution Imaging of Molecular Tension

Advanced Science, EarlyView.
Quantitative tension PAINT (qtPAINT) is a new method to quantify molecular tension at super‐resolution by exploiting force‐dependent DNA oligonucleotide dissociation kinetics. Combining hairpin tension probes and molecular‐beacon imagers, qtPAINT achieves 9–30 pN continuous force quantification range with 30–120 nm spatial and minute‐scale temporal ...
