Over 95% Optical Reflectance From Structurally Modulated All‐Biopolymer Multilayers

Advanced Materials, EarlyView.
A new dense–porous design turns ordinary polysaccharides into highly reflective photonic multilayers. Alternating dense pectin and porous cellulose nanofiber layers create strong refractive‐index contrast without inorganic or synthetic polymers, enabling nearly perfect visible reflection, high near‐infrared reflection, broadband metallic‐like colors ...

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

Advanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

A Noninvasive Approach to Study Localized Forces in 3D Epithelia

Advanced Materials, EarlyView.
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Tailored Cationic Visible‐Light‐Active Interfaces for Sustainable, Biodegradable Nanofibers With Dual‐Mode Antimicrobial Activity and Robust Electrostatic Particle Capture

Advanced Materials, EarlyView.
Surface co‐functionalization of biodegradable nanofibers with sodium copper chlorophyllin and quaternary ammonium compounds achieves synergistic antimicrobial activity through combined photodynamic and contact‐killing mechanisms. The cationic surface provides humidity‐resistant electrostatic particle capture while maintaining rapid enzymatic ...

Ferroionic‐Assisted, Charge‐Driven Polymorphic Phase Engineering for Multilevel Memristive Devices

Advanced Materials, EarlyView.
A CuInP2S6/Mo0.92W0.08Te2 heterostructure enables a gradual semiconductor‐to‐semimetal phase transition through Cu+ ion migration and charge accumulation. The spatially engineered 2H/1T′ mixed phases produce continuously tunable conductance states in a two‐terminal geometry, while suppressing depolarizing fields and stabilizing the metastable 1T′ phase.

Optical fibre plethysmograph

Journal of Biomedical Engineering, 1985
We describe a method for obtaining blood volume information from the external jugular vein or carotid artery by means of an optical fibre transducer. The device may be used to obtain accurate predictions of the state of the cardiac cycle, thereby enabling a range of physiological measurements to be made.
