Bacterial Biohybrids With Dual Magnet and Hypoxia Tropism for Ferroptosis Activation in Deep Tumor Regions

Exploration, EarlyView.
This study introduces a bacterial biohybrid (Ec@ZFOY) designed to target deep tumor regions using a combination of magnetic and hypoxia‐driven mechanisms for enhanced therapeutic delivery. By incorporating hypoxia‐targeted Escherichia coli and magnetic nanoparticles loaded with a HIF‐1α inhibitor, the biohybrid activates ferroptosis through reactive ...

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems

Laser &Photonics Reviews, EarlyView.
This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

Effect of Nanoparticles Type and Content on the Antimicrobial Activity of Magnetoelectric Polymer‐Based Composites

Macromolecular Bioscience, EarlyView.
Magnetoelectric P(VDF‐TrFE) nanocomposites containing CFO or Fe3O4 nanoparticles were developed to generate electroactive microenvironments under magnetic stimulation. At 1 Hz, particularly with 20% CFO, strong antimicrobial effects were observed against E. coli and S. aureus. This approach highlights the potential of magnetically activated surfaces to

Additive Manufacturing of Cobalt Iron Oxide‐Based Photopolymer Resin Magnetoactive Polymer Composites Through Stereolithography

Macromolecular Materials and Engineering, EarlyView.
In this study, novel resin/cobalt iron oxide magnetic actuation polymer composites (MAPCs) are synthesized and optimized for stereolithography (SLA)‐based 3D printing. Printing parameters are tuned for dimensional accuracy and print quality. Comprehensive physicochemical, mechanical, and magnetic characterization identifies the optimal formulation ...

Arsonic Acid Functional Polymers Enable Stabilization of Iron Oxide Nanoparticles in Aqueous Solution

Macromolecular Rapid Communications, EarlyView.
Arsonic acid containing diblock copolymers are developed to incorporate arsonic acid moieties for surface anchoring to IONPs, along with water soluble PEG blocks to impart colloidal stability in aqueous environments. The resulting polymer‐coated IONPs are evaluated for stability in physiological media and cytocompatibility.
