Mechanism‐Driven Nanoformulations for Cognitive Impairment Induced by Intermittent Hypoxia and Periodontitis

open access: yesAdvanced Materials, EarlyView.
Clinically, intermittent hypoxia (IH) is often accompanied by periodontitis, which accelerates cognitive impairment induced by IH. Novel Janus mesoporous gold‐silica nanoformulations (RVG‐Au&mSiO2‐TPP‐VB) enable intranasal delivery, achieve hierarchical targeting to neuronal mitochondria, effectively scavenge reactive oxygen species, inhibit the HIF‐1α/

A Geometrically Transient Platform for Bioelectronic Implants

open access: yesAdvanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

A Wireless, Passive Multimodal Wearable Sensor With Decoupled Sensing Capabilities

open access: yesAdvanced Materials, EarlyView.
A wireless passive multimodal electronic skin is presented for the simultaneous perception of pressure, humidity, and odor through a frequency‐divided LC resonator array. The decoupled sensing architecture suppresses cross‐interference and enables independent signal readout under superimposed stimuli while maintaining high stability.

Universal Strategy for Phase‐Selective Synthesis of Monolayer TMDs via Colloidal Chemistry

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Colloidal synthesis of monolayer transition metal dichalcogenides (TMDs) remains challenging regarding uniform size, thickness, and crystalline phase. While significant progress has been made in phase engineering, a unified chemical strategy for on‐demand selection of both 2H and 1T′ phases across multiple TMD systems within a single chemical ...
