In Star Trek, Dr. McCoy administered drugs right through the skin without needles. Shizouka University researcher Kazuo Shimizu and grad student Jaroslav Kristof are attempting something similar using a blast of ionized gas known as cold plasma to temporarily render the skin more permeable to drugs. Kristof says the technique reduces the amount of drug a patient would have to take.

JAROSLAV KRISTOF (Shizouka University):

It means that there’s less side effects, so it should be safer, and painless, because you have some pain when you use needles, so this should be also advantage.

HIRSHON:

So far they’ve tested the concept only on samples of pig skin, so it has a long way to go before being used on human patients. They report the research at the annual AVS symposium in Nashville. I’m Bob Hirshon, for AAAS, the science society.
