Separation of target material from a liquid sample is achieved by coupling the target to targetable encapsulated gas microbubbles, allowing the microbubbles and coupled target to float to the surface of the sample to form a floating microbubble/target layer, and separating this layer from the sample. In a positive separation process the microbubbles are then removed from the target, e.g. by bursting. In a negative separation process target-free sample material is recovered following separation of the floating layer. The method may also be used diagnostically to detect the presence of a disease marker in a sample. Novel separation apparatus is also described.
通过将目标物与可靶向的封装气体微泡耦合,可以从液体样品中分离目标物,使微泡和耦合的目标物浮到样品表面形成一个浮动的微泡/目标物层,并将该层与样品分离。在正分离过程中,微泡然后从目标物中移除,例如通过爆破。在负分离过程中,在分离浮层后,可以恢复无目标物的样品材料。该方法还可用于诊断性地检测样品中疾病标记物的存在。还描述了新型分离装置。
