感声的微小乳液液滴(其成分多为全氟碳化物,Perfluorocarbon),因其较低的沸点,可以通过体外的超声激励而实现液态-气态的状态转化,即气化。这种感声的乳液液滴可以成为包裹药物的载体实现超声激发的靶向药物释放;可以实现靶向超声造影成像;也可以用于栓塞疗法治疗肿瘤等。因感声乳液液滴在医学诊断和治疗方面具有广泛的应用潜力,成为医学超声领域的研究热点。然而,感声微液滴气化的物理机制尚不清楚。目前在实
Smell the tiny emulsion droplets (the composition of mostly perfluorocarbons, Perfluorocarbon), because of its lower boiling point, can be achieved by ultrasound in vitro excitation of liquid - gaseous state transformation, that is, gasification. This sensorial emulsion droplet can be used as a carrier for drug delivery to achieve targeted drug release by ultrasound excitation; targeted ultrasound contrast imaging can be achieved; and embolization can also be used to treat tumors and the like. Due to the sensory emulsion droplets in the medical diagnosis and treatment has a wide range of potential applications, become a medical ultrasound field of research focus. However, the physical mechanism of gas sensing microdrop vaporization is not clear. Currently in fact
