Abstract:
1. A method of manufacturing a multiple-phase particle comprising: preparing a channel including a first passage and a second passage, and the channel including an outlet port placed in a first fluid; feeding a second fluid into the first passage of the channel; feeding a third fluid into the second passage of the channel; guiding the second fluid and the third fluid to the outlet port alternately by guiding the second fluid from the first passage to the outlet port placed in the third fluid and guiding the third fluid from the second passage to the outlet port to be disrupted by the second fluid to form an alternating flow of the second fluid and the third fluid, at least the outlet port of the channel being made from a material to which the second fluid adheres to due to an affinity to the second fluid; retaining the second fluid at the outlet port by an effect of the affinity of the second fluid, the second fluid being higher in affinity to the outlet port compared with the first fluid, the second fluid retained at the outlet port acting as a boundary film between the first fluid and the second fluid; then, introducing a third fluid into the second fluid retained at the outlet port, the third fluid being lower in affinity to the outlet port compared with the second fluid, thereby entrapping the third fluid in the second fluid to form an intermediate body of the multiple-phase particle; introducing the third fluid into the second fluid retained at the outlet port, the intermediate body expanding to form the multiple-phase particle having a larger diameter than an inner diameter of the outlet port; and then, releasing the multiple-phase particle from the outlet port into the first fluid, resisting to an affinity of the multiple-phase particle to the outlet port.
