Life-size, biomimetic blood-brain barrier model makes animal models redundant

Thu, 12/21/2017 - 14:55
Crossing the blood-brain barrier (BBB) is the object of intensive research in nanotechnology and biomedicine for developing new therapies against brain cancer and for the treatment of neurodegenerative diseases. For this reason, it is extremely important to develop realistic models of the BBB, which mimic as most accurately as possible the in vivo environment. The development of high-resolution 3D-printing technologies has now enabled researchers to develop a realistic 3D bio-hybrid microfluidic model of BBB inspired by the in vivo neurovasculature.

Voltage-activated carbon monoxide sensor

Wed, 12/20/2017 - 20:10
The detection of carbon monoxide (CO) in the air is a vital issue, as CO is a highly toxic gas and an environmental pollutant. Carbon monoxide is poisonous because it blocks the binding site for oxygen in hemoglobin. It is exactly this principle - a porphyrin ring with a central iron or cobalt atom that the poisonous gas attaches to - that can be used to implement sensors to warn against carbon monoxide. While carbon monoxide sensors have been extensively researched and commercialized, none make use of a molecule that can be voltage-activated using a newly reported method.
