The brain is among the most “immune-privileged” of organs primarily through the highly selective permeability of the blood-brain-barrier (BBB), its minimal lymphatic drainage, the presence of ...

Borneol, a lipid‐soluble bicyclic monoterpene traditionally used in Chinese medicine, has emerged as a promising agent for enhancing drug delivery to the brain. Its unique ability to modulate the ...

(Nanowerk Spotlight) Biological potassium channels are marvels of selective permeability, allowing rapid transport of potassium ions (ionic radius of 1.3 Å) while blocking the smaller sodium ions (1.0 ...

Polymer membranes that "simultaneously and surprisingly" improve permeability while favoring bigger molecules over smaller ones have been developed by a team of researchers that includes Dr. Richard J ...

Chronic kidney diseases affect more than 10% of the world’s population, and most cases arise from disorders of the kidney’s filtration barrier, which is located within a million microvascular units ...

White blood cells act as the first line of defense in the immune system and are often referred to as an army that protects our body. Neutrophils account for the largest portion (55-70%) of white blood ...

Chemists from Würzburg have developed a novel model system for selective ion transport. The system, composed of a stable double layer with a nanographene-confined cavity, demonstrates high selectivity ...
