Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

Advanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Fetal hemoglobin and hydroxycarbamide moduate both plasma concentration and cellular origin of circulating microparticles in sickle cell anemia children

Haematologica, 2013
Microparticles are cell membrane-derived microvesicles released during cell apoptosis and activation processes. They have been described as bio-markers in various vascular diseases, including sickle cell anemia, and associated with an increased risk of ...

Remote Activation of Wnt Signaling and Cell Proliferation by E‐Cadherin Magnetomechanical Stimulation

Advanced Functional Materials, EarlyView.
A pioneering magnetogenetic toolkit enables non‐invasive, precise spatiotemporal modulation of intracellular Wnt/β‐catenin signaling. Functionalized magnetic nanoparticles (MNPs@E/EC15) target cellular E‐cadherins to generate localized magnetomechanical forces under low‐intensity magnetic fields.

Detachment of microparticles from electrode erosion and the subsequent breakdown

AIP Advances, 2019
Resulted from electrode erosion, microparticles is common and inevitable in gas switches. Once these microparticles acquire field-induced charge and flee into the gap, there micro-discharge, impact damage and field distortion may occur, which eventually ...

Scalable Fabrication of Thermally Reconfigurable Ge Metasurfaces Using Stencil Lithography for Mid‐Infrared Molecular Fingerprinting

Advanced Functional Materials, EarlyView.
Scalable stencil lithography enables resist‐free fabrication of high‐index Ge metasurfaces for mid‐infrared molecular fingerprinting. Reversible thermo‐optic tuning provides post‐fabrication spectral control for precise resonance–vibration mode alignment, enabling enhanced molecular fingerprinting of microplastic particles.

Release of Prometastatic Platelet-Derived Microparticles Induced by Breast Cancer Cells: A Novel Positive Feedback Mechanism for Metastasis

TH Open, 2017
Circulating platelets and platelet-derived microparticles are regulators of cancer metastasis. In this study, we show that breast cancer cells induce platelet aggregation and lead to the release of platelet-derived microparticles.
