Synthesis, modification, and chlorhexidine loading of polymer modified‐HM‐HAP particles: In vivo antibacterial analysis and cell cytotoxicity assessment

Smart Molecules, EarlyView.
This study presents the synthesis of hollow mesoporous hydroxyapatite (HM‐HAP) particles modified with different weights PEG and PEI. Chlorhexidine was loaded onto the particles. SEM analysis confirmed no significant morphological changes. Antibacterial activity was tested in vitro and in vivo using mouse oral bacteria, demonstrating promising results.

Endocytosis‐independent cytosolic entry of messenger RNA via fluorous bilayer zippering attenuating Toll‐like receptor signaling and enables ischemic tissue salvage

Smart Molecules, EarlyView.
The present study establishes a paradigm shift in synthetic mRNA delivery through the convergence of three orthogonal chemistries—perfluoro‐acylation, bio‐orthogonal click cross‐linking, and disulfide reduction—within a single, modular polymer architecture. Abstract A fundamental constraint of conventional messenger RNA (mRNA) delivery systems is their

Revealing the Atomic‐Scale Structure of the Copper–Sulfuric Acid Interface

Small Methods, EarlyView.
How do acids interact with metallic surfaces? Using a multidisciplinary approach of electrodeposition and 3D‐printing, a novel approach of micro‐corrosion cells enables cryogenic atom probe tomography at the liquid‐solid interface of dilute sulfuric acid in contact with copper at different time and thermal conditions. ABSTRACT Corrosion originates from

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

VIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

Extracellular vesicles in pharmacology: Innovations in drug delivery and therapeutic applications in cancer

British Journal of Pharmacology, EarlyView.
Extracellular vesicles (EVs) are a diverse population of membrane nanoparticles secreted by nearly all cell types, playing a key role in intercellular communication by transferring bioactive macromolecular cargo. In cancer, EVs shape both the local tumour microenvironment and distant premetastatic niches.
