Schematic of the laser-generated-focused ultrasound-mediated drug delivery. (A) Once the carbon black/PDMS LGFU transducer is excited by the pulsed-laser, the absorbed laser energy causes rapid heat-transfer and simultaneous thermal expansion of the LGFU lens. The laser-generated pulsed waves can promote the drug-release efficiency by cavitation effects and oscillation of the microgels’ shells. (B) Schematic of the experimental apparatus; a customized fixture is used to maintain the consistent position of the test tube at the focal spot.
