Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

Advanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

GaSex Nanoparticles Modulate Neutrophil Function and Mitigate NET‐Driven Osteogenic Impairment in Osteomyelitis Therapy

Advanced Materials, EarlyView.
Neutrophil extracellular traps (NETs) emerge as a critical repair‐limiting factor in osteomyelitis, driving osteoblast mitochondrial dysfunction and excessive PINK1/Parkin‐mediated mitophagy. Gallium–selenium nanoparticles (GaSex) scavenge reactive oxygen species, redirect neutrophils from NETosis toward bactericidal phagocytosis, eliminate methicillin‐

Comparison of Chromogenic Media with the Corn Meal Agar for Speciation of Candida

, 2018
In recent days, non albicans candida species are emerging, many of these species are inherently resistant to routinely used antifungals. Hence, the need for speciation of candida is important in the treatment point of view. Speciation of candida can be

Control of Bacterial Attachment on Macroporous PDMS/Paraffin SLIPS With Varying Lubricant Viscosity

Advanced Materials Interfaces, EarlyView.
Slippery liquid‐infused porous surfaces (SLIPS) prepared from macroporous PDMS, infused with medical‐grade paraffins, were systematically investigated regarding the correlation of viscosity, surface corrugation, bulk porosity, and bacterial resistance. Substrate porosity was found to dominate lubricant stabilization and the antifouling activity.
