A fluorous biphase drug delivery system triggered by low frequency ultrasound: controlled release from perfluorous discoidal porous silicon particles

“…The low frequency ultrasound (10–60 kHz) is known to enhance the permeability of biological membranes and improve the release efficacy of therapeutic agents. 44 The ultrasonic power density was determined calorimetrically as described by Hill et al 69 In this study, the application of fabricated fluorous particles with LFUS triggered controlled release was explored. The release experiments were performed with the fluorous particles on a silicon wafer aiming to establish a convenient observation by optical microscopy.…”
