Sonoporation: The application of high frequency ultrasound to living cells in order to facilitate the injection into the cells of materials such as genes or drug molecules. The aim is to develop a relatively non-invasive method for gene therapy and drug therapy of various conditions (such as tumors). It is like firing a beneficial bullet right into diseased region while limiting toxicity for surrounding non-diseased tissues. Early days yet for this technology.

Fancy drug delivery
Would benefit you and me
Far better that a tumor die
Than either you or I.
