Permeation characteristics of gramicidin conformers
Biophysical Journal, 1988 To investigate the molecular origin of decreased conductance in variant gramicidin channels, we examined the current-voltage (IV) characteristics of single Val1-gramicidin A channels. Unlike standard channels, all variant channels showed pronounced rectification even though bathing solutions were symmetrical.

Advanced Functional Materials, EarlyView.The study develops elastin–fibrin scaffolds and evaluates angiogenesis using the chorioallantoic membrane (CAM) model. Advanced imaging with confocal microscopy and Indocyanine Green dye enables precise 3D quantification of vascular networks. Findings demonstrate superior microvessel visualization compared to micro‐CT using Microfil and Optiray 350 ...

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration
Advanced Functional Materials, EarlyView.A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

High‐Throughput Microfluidic‐Mediated Assembly of Layer‐By‐Layer Nanoparticles
Advanced Functional Materials, EarlyView.The layer‐by‐layer (LbL) assembly of polymer films on nanoparticle (NP) surfaces is a promising technique for targeted drug delivery. Despite its success in preclinical mouse models, a current good manufacturing practices (cGMP) compliant, clinical‐scale production method has been lacking.

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.
