Surprising Water Slipping Performance on Highly Hydrophilic PEG‐Derived Monolayer‐Covered Surfaces: Preparation, Mechanism, and Application

Advanced Functional Materials, EarlyView.
Highly hydrophilic surfaces (water contact angle, ≈17.7°) exhibiting surprising water slipping performance (sliding angle, ≈7.3°) are successfully prepared via simple chemisorption of polyethylene glycol (PEG) organosilane and subsequent alkali‐treatment.

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy

Advanced Healthcare Materials, EarlyView.
Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.

Long‐Term Hydrophilic, Anti‐Clotting, and Anti‐Fibrotic Dynamic Covalent Silicone‐Based Biomaterials

Advanced Healthcare Materials, EarlyView.
Dynamic covalent crosslinking of a Schiff‐base silicone elastomer with hydrazide‐functionalized polymers is demonstrated to improve the long‐term hydrophilicity as well as the anti‐fouling and anti‐clotting properties of PDMS implants. The hydrazone‐functionalized material prevents hydrophobic recovery, resists clotting, and significantly reduces ...
