How Extremely Tiny Diamonds Could Be Used To Deliver Drugs


diamondWhat good is a diamond so small that you need one of the most powerful microscopes in the world to see it? Scientists are working on ways to use these tiny treasures to deliver drugs more effectively.

Nanodiamonds are much like the diamonds you've seen on expensive jewelry — they are faceted, extremely hard and made up of carbon atoms — but shrunk down to a mind-bogglingly small scale. Whereas a typical sheet of paper is about 100,000 nanometers thick, a nanodiamond is just four to six nanometers across. At this minuscule scale, physical properties emerge that make the diamonds very desirable for drug delivery and could help pave the way to personalized medicine, according to a report published in the journal Science Advances.
