5 news bits – nitric oxide and nanoparticles

English: An experimental setup used to measure the fraction of exhaled nitric oxide (FeNO) in human breath samples. The subject blows into the tube (1) after a mouthpiece (2) has been connected to it. The wires on the side measure parameters like breath velocity, while the exhaled gas is taken to a FeNO analyzer (3). (Photo credit: Wikipedia)

The first item is about nitric oxide (NO) used in testing, and the rest are all about using nanoparticles for delivering things into the human body, including NO. It’s astounding that scientists have found nanotechnology so helpful in these kinds of applications. I just hope more research is done on how safe it is to inject nanomaterials into our bodies or make us breathe them in. Their size is so similar to the deadly asbestos fibers that are currently costing billions in lawsuits by workers whose companies didn’t protect them from breathing and ingesting them.

Gotta make sure the cure doesn’t damage the patient in different ways than the condition it’s meant to help.
