Five per cent glycerin is also present in Alevaire, to prevent evaporation of droplets, to stabilize droplet size and to assure the carrying of actual liquid droplets into the bronchial passages.

Engineers and scientists have developed proof of concept for a robot that can reach some of the smallest bronchial tubes in the lungs - to take tissue samples or deliver cancer therapy. Known as a ...

The robot tentacle, which measures around 2 mm in diameter, can reach the smallest bronchial tubes in the lungs - unlike current technology. Researchers in the UK have created a robot tentacle ...
