Spatial Cell Death and Oxidative Stress Dynamics in Gas Plasma‐Treated Tumor Tissues

open access: yesAdvanced NanoBiomed Research, EarlyView.
Schematic representation of the four experimental models to study tissue penetration and oxidation. Four tissue models were used. Human pancreatic cancer cells were grown on the chorioallantois membrane of chicken embryos and gas plasma‐treated in ovo, murine colorectal tumor tissue was gas plasma‐exposed ex vivo, murine squamous cell carcinoma cells ...

Enhancement of Dissymmetry Factors Through Axial Elongation of Hetero[n]helicenes

open access: yesAngewandte Chemie, EarlyView.
A benzofuran scaffolding strategy enables the synthesis of hetero[9]‐, [12]‐, and [15]helicenes. Structural and chiroptical analyses demonstrate that systematic axial elongation increases helical distortion and significantly amplifies luminescence dissymmetry.

Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods

open access: yesAdvanced NanoBiomed Research, EarlyView.
Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...

Solvent Hydrogen Bonding Determines Adsorption Geometry of Trimesic Acid on Cu

open access: yesAngewandte Chemie, EarlyView.
Water reorients adsorbate molecules. Combined tip‐enhanced Raman spectroscopy, density functional theory and molecular dynamics simulations reveal the adsorption geometry of trimesic acid on Cu. Subtle adsorbate–substrate–solvent energy differences due to hydrogen bonding dictate molecular orientation at solid/liquid and solid/gas interfaces, providing

Safety and Feasibility of Magnetic Separation‐Based Blood Purification

open access: yesAdvanced NanoBiomed Research, EarlyView.
We present the preclinical biological safety and translational feasibility of a magnetic nanoparticle‐based extracorporeal blood purification platform for removal of disease‐causing blood factors. ISO 10993‐compliant studies and exaggerated worst‐case exposure models demonstrate efficient nanoparticle extraction (≥99.9%), favorable biocompatibility ...

Au(I) Complex With an Abnormal Carbene Ligand Shows Anti‐Kasha Dual Photoluminescence Emission

open access: yesAngewandte Chemie, EarlyView.
Incorporation of an abnormal N‐heterocyclic carbene into a heteroleptic linear Au(I) complex induces anti‐Kasha dual emission responsive to biologically relevant phenyl sulfate. ABSTRACT We report the first photoactive linear Au(I) complex with an abnormal N‐heterocyclic carbene (aNHC) ligand, Au(aIm)(Cz).

Cycloazulenylen

open access: yesAngewandte Chemie, EarlyView.
Ein ausschließlich aus Azulen‐Untereinheiten aufgebauter gespannter Makrocyclus mit der Bezeichnung [6]Cycloparaazulenylen ([6]CPA) wird vorgestellt. Der Makrocyclus weist für ein Azulensystem eine bemerkenswert kleine HOMO–LUMO‐Energielücke, eine durch die Ringspannung hervorgerufene bathochrome Verschiebung der Absorption sowie ein ungewöhnliches ...
