The rationale behind this approach is that drug encapsulation in micelles decreases systemic concentration of drug, diminishes intracellular drug uptake by normal cells, and provides passive drug targeting of tumors, thus reducing unwanted drug interactions with healthy tissues. Ultrasound irradiation is used to release drug from micelles at the tumor site and to enhance the intracellular drug uptake by tumor cells. An important advantage of ultrasound is that it is noninvasive, can penetrate deep into the interior of the body, can be focused and carefully controlled.
