Investigating the mechanism of acoustically activated uptake of drugs from Pluronic micelles

<p>Abstract</p> <p>Background</p> <p>This paper examines the mechanism of ultrasonic enhanced drug delivery from Pluronic micelles. In previous publications by our group, fluorescently labeled Pluronic was shown to penetrate HL-60 cells with and without the action of ul...
