Carbon monoxide releasing molecules (CORMs) have been intensively studied in the past decade due to the therapeutic effects of CO. The potential to control the release of CO to a specific target is one of the major advantages of CORM. In this work an ultrasound responsive micelle with pluronic as the shell and CORM-2 as the core were developed. The micelle released CO in the presence of cysteine. After the CO release stopped, applying ultrasound to the micelle suspension produced additional CO. About 1/3 of total CO can be controllably released by ultrasound. The mechanism of the ultrasound induced CO release is interpreted by the reaction between cysteine and CORM-2 inside the micelle.
