Burn‐Safe Biodegradable Magnetocaloric Composites for Temperature‐Controlled Biomedical Applications

open access: yesAdvanced Science, EarlyView.
This work investigates a magnetocaloric (Mn,Fe)2(P,Si) compound tailored for precise, self‐regulating heating in biomedical use. With a Curie temperature tuned at 43 °C, it enables therapeutic activation without overheating. Encapsulation in a composite ensures controlled temperature rise under an alternating magnetic field (AMF), with high ...

Additive‐Free Ti3C2Tx MXene Actuator with Large Deformation, Programmability, and High‐Humidity Stability via Precise Interlayer Spacing Control Engineering

open access: yesAdvanced Science, EarlyView.
By sequentially assembling MXene nanosheets with significant size differences, a multistimulus responsive additive‐free MXene actuator with gradient structure is obtained. An innovative cyclic low‐temperature annealing‐rehydration technology is proposed, which achieves precise control of interlayer d‐spacing, initial shape, and actuation behavior of ...

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

open access: yesAdvanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

A Hydrodynamic Bioreactor for High‐Yield Production of Extracellular Vesicles from Stem Cell Spheroids with Defined Cargo Profiling

open access: yesAdvanced Science, EarlyView.
This study harnesses hydrodynamic flows to generate, confine and stimulate stem cell spheroids, enabling the large‐scale production of extracellular vesicles (EVs). This innovative method not only streamlines spheroid formation and subsequent EV release in a single, integrated process, but also ensures the generation of EVs with enhanced biological ...

A Microfluidic Digital Shutter of Liquid–Liquid Interface for Fabrication of Multifaceted Hydrogel Microfiber Structure

open access: yesAdvanced Science, EarlyView.
A programmable passive digital shutter based on multiphase liquid–liquid interface dynamics is introduced for precise fabrication of hydrogel microfibers. By modulating the shutter operation, microfibers with tunable geometry—including linear, helical, tadpole‐like, and spherical forms—are produced.
