Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

open access: yesAdvanced Science, EarlyView.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Synergistic Dual Slip‐Link Toughening of a Water‐Rich Double Network Hydrogel Combining Slide‐Ring and Highly Entangled Networks

open access: yesAdvanced Science, EarlyView.
Two distinct slip‐link mechanisms – the slide‐ring pulley effect and highly entangled chains – are combined in a water‐rich double network hydrogel, achieving synergistic toughening, near‐complete reversibility, and exceptional friction tear resistance at >$>$91 wt.% water.

A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair

open access: yesAdvanced Science, EarlyView.
A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration.

Solution Confirmation of UVC-Irradiated Low-Molecular-Weight Heparin

open access: yesPhyschem
Heparin is a highly sulphated polyelectrolyte, and its properties depend strongly on its shape in solution. In this study, we closely examined the structural behaviour of low-molecular-weight heparin under aerobic ultraviolet-C (UVC, 100–280 nm ...

Oligopeptides/DNA Coacervate Droplets as Macromolecular Delivery Microcarriers

open access: yesAdvanced Science, EarlyView.
Oligopeptide–DNA coacervates formed via liquid–liquid phase separation serve as programmable carriers for macromolecular cargos, entering cells through lipid raft–associated pathways and subsequently undergoing enzyme triggered intracellular disassembly driven by DNA degradation processes, thereby enabling efficient, controlled, and spatially defined ...

Geometry‐Controlled Assembly of Self‐Standing Nanorods With Undisturbed Plasmonics

open access: yesAdvanced Science, EarlyView.
This study reports a geometry‐driven assembly strategy to vertically align Au@Ag core–shell nanorods on PS beads. This well‐defined architecture enables the preservation of the intrinsic optical response of individual nanorods. Thus, demonstrate a highly reproducible SERS enhancement with exceptional uniformity.

Differential hydration lubrication performance of polyelectrolyte-modified UHMWPE promoted by diverse charge characteristics

open access: yesFriction
Hydrated ions can achieve exceptional hydration lubrication through their adsorption onto oppositely charged surfaces. Similarly, the charge characteristics of polyelectrolytes are expected to significantly impact the hydration lubrication performance of
