Maintaining therapeutic concentrations of microbubbles and drugs at the clot site, however, poses a challenge. The objective of this study was to investigate the effect of magnetic microbubble targeting upon clot lysis rates in vitro. Retracted whole porcine blood clots were placed in a flow phantom of a partially occluded middle cerebral artery. The clots were treated with a combination of tissue plasminogen activator (0.75 µg/mL), magnetic microbubbles (∼107 microbubbles/mL) and ultrasound (0.5 MHz, 630-kPa peak rarefactional pressure, 0.2-Hz pulse repetition frequency, $2\%$ duty cycle). Magnetic targeting was achieved using a single permanent magnet (0.08–0.38 T and 12-140 T/m in the region of the clot). The change in clot diameter was measured optically over the course of the experiment. Magnetic targeting produced a threefold average increase in lysis rates, and linear correlation was observed between lysis rate and total energy of acoustic emissions.}, cin = {JCNS-FRM-II / JCNS-1 / MLZ}, ddc = {570}, cid = {I:(DE-Juel1)JCNS-FRM-II-20110218 / I:(DE-Juel1)JCNS-1-20110106 / I:(DE-588b)4597118-3}, pnm = {6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623) / 6G15 - FRM II / MLZ (POF3-6G15)}, pid = {G:(DE-HGF)POF3-6G4 / G:(DE-HGF)POF3-6G15}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:30773375}, UT = {WOS:000464126800011}, doi = {10.1016/j.ultrasmedbio.2018.12.014}, url = {https://juser.fz-juelich.de/record/862255}, }
