While cleaning up the space ship may appeal to those in love with Mr. Clean, it may be better for space agencies to coat their space craft walls with anti-germ paint instead.
(Fox News) Scientists at the University of South Dakota have invented a new germ-killing molecule that can be added to commercial brands of paint to give the paint long-lasting antimicrobial properties.
The molecule includes a bleach-like substance called an N-halamine. N-halamines are already used widely, but the South Dakota researchers were able to develop a new type known as Cl-TMPM. [...]
In tests, Staphylococcus aureus organisms were killed with 10 minutes of contact, and E coli organisms were killed with 5 minutes of contact. Paint treated with Cl-TMPM was even effective against the superbug MRSA and other drug-resistant bacteria.
Unfortunately the new paint is only effective against a small selection of organisms, although hopefully ...
