Material‐Gradient Enabled Enhancement of Strength and Strain‐Hardening of Lattice Structures

open access: yesAdvanced Science, EarlyView.
This study employs material gradients in lattice structures via alloy‐controlled additive manufacturing, decoupling mechanical behavior from geometry. Gradients guide stable plastic fronts, enhancing plateau stress and energy absorption by up to 25.4%.

Unique Aerofoil‐Structured Microfluidics for High Throughput Lipid Nanoparticle Formulation Screening and Scale‐up

open access: yesAdvanced Science, EarlyView.
This study presents aerofoiled microfluidic structures optimized for efficient mixing and lipid nanoparticle (LNP) formation across broad flow rates. Based on this design, two dedicated systems are introduced: MiNANO‐form for high‐throughput formulation screening and MiNANO‐scale for continuous large‐scale production, enabling reproducible, high ...

Mechanical Stretch‐Induced Interlayer Coordination between MMP2 and COL17A1 Exacerbates Regenerative Exhaustion in Skin

open access: yesAdvanced Science, EarlyView.
Regeneration reaches a hidden limit under mechanical stretch. Prolonged tension alters dermal–epidermal communication, exhausting epidermal stem cells via MMP2–COL17A1 signaling. MMP2 inhibition by Marimastat preserves adhesion and regenerative capacity, offering a potential strategy to overcome the inherent boundaries of skin expansion.

Nanoparticle‐Functionalized Cellulose Through Biosynthesis‐Only Approach

open access: yesAdvanced Science, EarlyView.
This study reports the first covalent incorporation of glucose‐modified carbon dots (Glu‐CDs) into bacterial cellulose (BC) via microbial fermentation, resulting in BC nanofibers that exhibit uniform cyan fluorescence. A 3D‐printable hydrogel (Glu‐CDs‐BC‐SA) is developed, facilitating the fabrication of fluorescent structures. This work demonstrates an
