The first drugs designed to target the genes have begun clinical trials in the United States on patients with arterial disease and diabetes-induced nerve damage.

Resently years, researchers utilize biological effects generated by microbubble contrast agent combined ultrasound techniques to implement therapy of tumor by microbubble carrying drug and gene.
