Ultrasoft Iontronics: Stretchable Diodes Enabled by Ionically Conductive Bottlebrush Elastomers

Advanced Functional Materials, EarlyView.
This work introduces a solvent‐free, ultrasoft, and stretchable ionic diode based on oppositely charged bottlebrush elastomers (BBEs). The BBE diode exhibits an ultralow Young's modulus (<23 kPa), a high rectification ratio of 46, and stretchability over 400%.

Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.

A Universal Biomimetic Approach for Making Artificial Antigen‐Presenting Cells for T Cell Activation

Advanced Functional Materials, EarlyView.
This study shows a biomimetic silica microcapsule (SMC) fabrication method under mild conditions for making artificial antigen‐presenting cells (aAPCs). Inspired by marine biomineralization, peptide‐mediated biosilicification enables silica shell formation on emulsion templates. The resulting SMCs possess a core–shell structure, controlled fluorescence

Dual‐Nanoparticle Engineered Hydrogel Reverses Bicellular Oxidative Stress to Accelerate Diabetic Fracture Healing

Advanced Functional Materials, EarlyView.
CD105‐LNPs and PS‐LNPs can deliver α‐lipoic acid to bone marrow mesenchymal stem cells and bone marrow‐derived macrophages, reversing high glucose‐induced oxidative stress while enhancing osteogenesis and M2 polarization. Integrating both nanoparticles into glucose‐responsive hyaluronic acid hydrogel forms DLNPs@HA hydrogel, which accelerates diabetic ...

The Approach to Sensing the True Fetal Heart Rate for CTG Monitoring: An Evaluation of Effectiveness of Deep Learning with Doppler Ultrasound Signals

Bioengineering
Cardiotocography (CTG) is widely used to assess fetal well-being. CTG is typically obtained using ultrasound and autocorrelation methods, which extract periodicity from the signal to calculate the heart rate.

Microbubble‐Controlled Delivery of Biofilm‐Targeting Nanoparticles to Treat MRSA Infection

Advanced Functional Materials, EarlyView.
Here, an effective strategy using microbubble (MB)‐controlled delivery of biofilm‐targeting nanoparticles (BTNs) for removal and therapy of methicillin‐resistant Staphylococcus aureus (MRSA) biofilm infections is introduced. In vivo delivery of MB with BTN is demonstrated to silence key bacterial genes involved in biofilm formation (icaA), bacterial ...

Pericyte‐Assisted Vascular Lumen Organization in a Novel Dynamic Human Blood‐Brain Barrier‐on‐Chip Model

Advanced Healthcare Materials, EarlyView.
Organ‐on‐Chip (OoC) technology enables the precise modeling of the blood‐brain barrier (BBB). This study presents a microfluidic device that mimics brain microvessels, integrating co‐culture with pericytes and astrocytes under pulsatile flow. Results show that perivascular cells modulate endothelial morphology, promoting lumen formation and barrier ...
