However, by coating the tubes in metals or other materials, they become more stable.
The process has allowed BYU physics professor Robert Davis and colleagues to create structures such as the BYU logo, as well as practical, very precise micro-filters.
"One application is in the area of compressed gases like oxygen in the areas of health care, mining operations or scuba diving," Davis was quoted as saying in a release. "Compressed gas systems can generate particles that need to be filtered out."
The nano-Cupid follows a somewhat similar feat though on a smaller scale -- in 2009, Brigham researchers spelled "BYU" using strands of DNA.
So what do you have planned for Valentine's? Got any scientastic ways of saying "I grok you"?
