Engineering the Hierarchical Porosity of Granular Hydrogel Scaffolds Using Porous Microgels to Improve Cell Recruitment and Tissue Integration

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

Advanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Evaluation of Antimicrobial Efficacy Against E. Coli Isolates of Different Serogroups Obtained From Diarrhoeic Neonates of Calves, Kids, and Lambs [PDF]

, 2012
Fourteen antimicrobials were evaluated their efficacy against 115 Escherichia coli isolates recovered from faecal samples collected from neonatal diarrhoeic calves (66), kids (25) and lambs (24). Of these isolates 37 were nontypeable, four were of rough

Antibiotics and the Human Gut Microbiome: Dysbioses and Accumulation of Resistances

Frontiers in Microbiology, 2016
The human microbiome is overly exposed to antibiotics, due, not only to their medical use, but also to their utilization in farm animals and crops. Microbiome composition can be rapidly altered by exposure to antibiotics, with potential immediate effects

Optimizing Angiopep‐2 Density on Polymeric Nanoparticles for Enhanced Blood–Brain Barrier Penetration and Glioblastoma Targeting: Insights From In Vitro and In Vivo Experiments

Advanced Functional Materials, EarlyView.
The Angiopep‐2 peptide density on polymeric nanoparticles significantly impacts blood–brain barrier (BBB) penetration. This study explores this nuanced relationship using various in vitro models and in vivo assays, revealing that dynamic models better predict BBB penetration.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

Advanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.
