Abstract

New ways to administer drugs without a needle have been developed. Using an erbium doped yttrium aluminum garnet laser induced microjet, the same technique may be used to develop painless tattoos. A piece of pig skin is placed underneath the laser which is set at 2940nm, a wavelength well absorbed by water. The laser is then pulsed at 150μS while ink is ejected from the microjet onto the surface of the pig skin. Results indicate that Er:YAG laser induced microjets can imbed ink into epidermis. Using this technique, the word IMSA was successfully tattooed into the skin of a pig in one minute. These results indicate the potential use of these microjets in the future in a less painful and quicker manner.
